What is the best table lamp for a student? How to choose a good table lamp for a student What is inside a light bulb for children

When choosing a lamp for desktop use, the most important thing is to evaluate how it will help to maintain the hygiene of children's vision. The safety and ergonomics of the device are also important. The overall design and decorative elements are a secondary matter, especially when it comes to a table lamp for a student.

What should be the ceiling

The shape and color of the ceiling of a table lamp for a student should be such that:

The child did not experience discomfort from blinding light.
Bright design did not distract the student from working on homework.
The emitted luminous flux was evenly distributed over the surface of the working area.

All three conditions are met by ceiling lamps in the form of a cone or trapezoid, muted color shades, completely hiding the light bulb.

Ophthalmologists call green the best color for visual perception. It helps to relax the ciliary muscle of the eye, which has a positive effect on the well-being of the child. But shades of all shades of red and orange are undesirable for a children's table lamp: these colors excite the nervous system and interfere with concentration.

How to choose the type of lamp for a table lamp

Incandescent lamps today are considered "archaic". Ophthalmologists and teachers do not recommend using them to illuminate children's work areas. They flicker and get very hot during operation. The first is harmful to the eyes and general health, the second creates a risk of burns when accidentally touching hot glass. But it is worth noting that incandescent lamps have a color rendering index (CRI) of at least 90%.

CFL (compact fluorescent lamps) also not the best choice for a children's table lamp. They contain mercury, so if broken, the child risks being poisoned by dangerous metal fumes. Besides, ripple factor CFL is also high, as a result of which the student quickly gets tired when doing homework. And the color rendering index (CRI) of CFLs is usually no more than 70-80%.

Experts recognized the safest and most effective light-emitting diode (LED) table lamps for schoolchildren. These lamps, subject to their quality workmanship:

do not pulsate;
do not burst;
have a good color rendering coefficient of more than 80%, which allows you to transfer all shades of illuminated objects;
emit light that is pleasing to the eye.

If a child accidentally touches a working LED lamp, he will not even pull his hand back, since the heating temperature of such a device is minimal.

What power should be a light bulb in a table lamp

Ophthalmologists recommend screwing only 60 W incandescent lamps into table lamps for schoolchildren. They evenly illuminate the surface and do not dazzle. The LED lamp, of course, should be less powerful: 8 watts is enough to create the same lighting conditions. But different lamps with the same power can emit different amounts of light, sometimes by 30-40%.

It is better to focus not on this approximate indicator, but on the actual illumination of the table with a lamp, which is easy to check using a light meter-brightness meter-pulse meter RADEX LUPIN. The illumination of the children's working area should be at least 300-500 lux. The same measuring device will show ripple factor light, the maximum allowable value of which is 10%, when working with a computer - 5%.

How to decide on the shade of the glow of the lamp

The color of the lighting also affects the comfort of using a table lamp, this is especially important for a student. The same ophthalmologists unequivocally recommend warm white light for children's rooms and warn of the dangers of "cold" lighting with a bluish tint for the child's retina.

Information about the color of the glow of the LED lamp is on the package. There you will also find the exact value of the color temperature, measured in Kelvin. The higher it is, the more unnatural the artificial light will seem. Ideal values are 2700-3000 K.

What else to look for when choosing a table lamp

When buying, it is also important to determine the design features of the lamp. To illuminate the student's work area, you can not use table lamps on a rigid short tripod. Popular fixtures with a flexible bending “leg” of medium height are much better. But the most ergonomic are devices on a long tripod, the angle of which can be adjusted. Such lamps are easily fixed in the optimal position for drawing, writing, creative work.

Another important property of a table lamp for a student is stability. The base must be heavy enough or screwed to the table, then the device will not fall and create a traumatic situation for the child. Also pay attention to what texture the surface of the base of the lamp has. The gloss will glare, so for schoolchildren, choose lamps with a matte base.

Recently, table lamps with maintenance-free light-emitting elements have begun to appear on sale. In low-quality samples of such lamps, a diffuser is installed which cannot create a uniform luminous flux. It looks like bright dots on the diffuser panel. In a high-quality table lamp, this should not be the case.

Questions for children:

1. Why do people feel bad without electric light?

2. Do you think there have always been light bulbs?

(children's answers)
Educator: A long time ago, people lived in caves, lit a fire on which
cooking and warming up. From the fire in the cave it was light and warm.
(See illustration.)

Many, many years have passed, people began to live in houses.
The fire had to be hidden in a stone and brick oven.
Why? (Answers of children).

In the evenings, to make it light, they lit a torch.
What is a ray? (Answers of children).
A splint is a dry, thin and long sliver. (See illustration).
(Experiment): light a sliver and invite the children to answer the questions:

1. How long did the torch last?

2. Was it convenient for people?

Yes, it was not very convenient, and people came up with a candle. (Perform the same experiment with a candle), put a glass or saucer under the flame, see dig and draw a conclusion with the children.
Now candles are lit on New Year trees, on holidays. And a hundred, two hundred years ago, candles burned in palaces, on the streets, in houses, theaters. When many candles were burning in the room, it became hot and stuffy. Over time, people invented the kerosene lamp.
(See illustration), you can show a real kerosene lamp and talk about its work. With such a lamp it was possible to go out in the rain, and in the snow, and in the wind.
The houses are light, but the street is dark-dark. This is how people invented street lights.
Pipes brought gas to the lanterns, in the evening a man lit each lantern, climbing a ladder. It was inconvenient. (See illustration).
Guess the riddle - “the light in the glass is sealed, as its owner lit it”
(Answers of children).
Of course, it's an electric light bulb. It was invented by Russian engineer Alexander Lodygin. The light bulb is very convenient, why do you think?
(Answers of children).

1. Yes, it shines brightly, click - lit up, click - went out. No smell, no smoke.

2. Guys, where do people use an electric light bulb now. (Review of illustrations, conclusions of children.)

The course of the game complex

teacher (B). Guys, listen... Is someone crying?

Fits in a closed box. The teacher looks into the box.

Guess what I saw in this box:

The sun shone brightly

But when it left

We immediately felt sad

Very gloomy and dark.

Only I do not lose heart -

And I turn on the light.

The sun lives in a vase

The vase pours wonderful light!

Here it is, magical

The sun is electric!

Who can help us answer

What kind of vase shines for us?

Children. This is a lamp! (Children find a light bulb model in the box).

AT. Light bulb, why are you here? Why are you crying? Guys, what do you think could happen to this light bulb? (She was lost, she was forgotten, she was left alone, etc.)

Let's ask her ourselves.

Bulb. Oh, I'm unhappy ... Everyone forgot me, abandoned me, left me .... I lived in a house with a large and friendly family: the girl Anya, the boy Vanya, their mother and father, grandparents. But they really offended me...

The girl Anya went to kindergarten and was a terrible coward.

AT. Children, what do you think, why could the light bulb be offended by the girl Anya? (The girl Anya was afraid of the dark, did not turn off the light in the room even during the day).

Guys, are any of you afraid of the dark? What can be scary in the dark? (You can fall, hit, get hurt; you can be afraid of an unfamiliar object, etc.)

Let's try to imagine ourselves in the place of this girl, let's play the dark room game.

Target: develop the ability to recognize familiar objects in a darkened room; stimulate the development of visual and tactile perception, develop the ability to correlate a schematic image with an object.

Game actions: recognize an object by touch and name it.

AT. Sometimes there is an accident at a power plant, a power line break. People in houses have to do something in the dark. For example, find a candle, matches. Have you ever tried to turn off the lights in the whole house in the evening? What did you feel? what does a person do in such a case?

Children. It immediately becomes dark, uncomfortable and even a little scary. You have to walk with your hand outstretched in front of you so as not to stumble on the furniture, as if you were blind! Even when your eyes get used to the darkness, you cannot find your favorite toy, read, draw, stumble where you would never stumble during the day... I want to turn on the light as soon as possible.

AT. Imagine that you are in a dark room. This box for your hands is a big dark room. There are various items there.

Each of you gets a card that shows one of the items. You need to find the same object in this “dark room” by touch.

AT. Guys, I see you are not afraid of the dark at all! Well done. What can we advise the girl so that the Light Bulb does not take offense? (Turn on the light only when necessary).

Bulb. Well, guys, is it convenient to play, read, work without light? You understand what an electric lamp is for! (It is needed in order to give light wherever a person is - at home, on the street, in transport and other places).

Ancient people lived in caves and did without electric light. How did they light up their home? (Bonfire). Do you know my ancestors - how did people illuminate their homes at different times?

AT. Guys, let's tell the light bulb its story!

Word game "The story of the light bulb"

Target: to consolidate children's ideas about the history of the appearance of an electric light bulb; stimulate the development of coherent speech.

Game actions: pick up cards in accordance with the appearance of an object in people's lives, make a chain and talk about the object.

Material: pictures for the game "The story of the light bulb."

Educator. How was human housing illuminated before the advent of electric light? Recall your stories about the history of the light bulb that you composed with your parents.

Sample children's stories:

The child puts the first picture “sun”: “Before a person learned to use fire, the only thing for him was the sun. But when night fell, people were threatened by wild animals that saw well in the dark and could attack a person. If the night caught people in the forest, they could get lost and not find their way home.

The second picture is “bonfire”: “When a person learned to make fire and keep it, the fire became for a person both light and warmth in a cave. It burned in the cave, giving both light and heat, and served as protection against predators.”

The third picture is a “torch”: “Then people illuminated their dwellings with torches. This is the most common sliver, only pointed at the end. Usually a torch was made of birch: this tree burns better than others. One end of the torch was fixed, and the other was lit. There is little light from the torch, it quickly burns out and smokes a lot, it had to be changed often, to make sure that there was no fire.

Picture “candle”: “From beeswax, people learned to make candles that burned longer than a torch. Inside the candle there is a wick made of thread. This very convenient invention is used and today they are often used as New Year's gifts.

What do you think is the disadvantage of a candle?

Children. You can burn yourself with it, there can be a fire from it, it smokes, it gives little light.

Picture "kerosene lamp": "Gradually, people learned how to extract various minerals: coal and oil. Then kerosene lamps appeared, in which you can make the flame stronger or smaller at the request of the owner. It was economical and convenient. Behind the glass flask, the flame became safe.

Was the kerosene lamp convenient? Why?

Children. The kerosene lamp did not light the room well; kerosene had to be constantly poured into it. If someone accidentally knocked over the lamp, the kerosene spilled and a fire broke out.

Picture "electric light bulb": "When a person learned about electricity, he invented an electric light bulb. She still illuminates our apartments and streets. Now in our homes there are many different beautiful lamps - which ones do you know? (Chandeliers, sconces, table lamps, floor lamps).

Bulb. Thanks guys, I'm so glad to hear from you! You seem to know a lot about me...

AT. What made you sad again?

Bulb. Many people know about electricity, about my history, but ... they do not feel sorry for me, they do not know how to use it correctly. For example, the boy Vanya had a lot of battery-powered toys. But he broke them all...

AT. Why could the light bulb be offended by the boy Vanya? (When his parents did not see him, Vanya twisted all the light bulbs out of toys). Guys, why can't you do this? (A toy deteriorates, a light bulb can deteriorate, break, this action is dangerous for children, etc.).

Where else can we find a light bulb?

The game "Where does the light bulb live?"

Target: to consolidate children's ideas about electrical appliances, to stimulate the development of coherent speech.

Game actions: choose pictures depicting objects that have a light bulb, indicate its place on the object using a small symbol, explain its purpose.

Material: pictures depicting various objects; red cardboard circle.

Game progress

AT. Find in the pictures only those objects that can contain an electric light bulb. Mark this picture with a red circle. Explain why this item needs an electric light bulb.

Pictures: refrigerator, table, TV, bookshelf, vacuum cleaner, fur coat, telephone, vase, stove, book, iron, carpet, battery toys, flashlight, computer, audio tape recorder, radio, record player, alarm device, mixer, etc.

AT. A light bulb is a necessary element of any electrical appliance.

Bulb. Mom in this family works all day at work, but what else does she have to do at home? (Washes, cooks, cleans, sews, etc.)

AT. Why could Light Bulb be offended by Anya and Vanya's mother? (Included at the same time electrical appliances)

Bulb. Guys, what do you think, is it always necessary to use an electrical appliance in everyday life? Can mechanical devices be used? Why?

AT. Dear Light Bulb, we will now play with the guys in the game "Find the right objects", in which you can also participate!

Game "Find the matching items"

Target: to consolidate children's ideas about how to act with various electrical devices, to stimulate the development of mental logical operations, coherent speech.

Game actions: the “Good” command names the positive aspects of using a particular household appliance. The "Bad" team finds negative points in using the same device.

Material: pictures depicting a variety of household appliances and similar household items.

AT. Choose from a set of pictures a pair of objects that match each other in action. For example, an electric mixer, a mechanical mixer, a whisk.

Refrigerator - pantry, cellar;

Electric kettle - an ordinary kettle;

Washing machine - washboard and basin with water;

Dishwasher - kitchen sink;

Toaster - frying pan - brazier for a fire, etc.

AT. Now you understand how important a light bulb is in our life? Without it, the whole world would become dark and gloomy. In order for our world to be illuminated by electricity, we must treat it carefully, economically, be attentive, turn off the lights and electrical appliances in time so as not to waste electricity.

Bulb. The father in this family does not like to fix household electrical appliances. There were a lot of them in the pantry.

AT. Guys, can we help him “fix” all the appliances?

The game "Lay out of the sticks»

Target: Exercise children in independent searches for ways to draw up figures based on preliminary reflection on the course of the solution.

Game actions: make the contour of an object from counting sticks in accordance with the proposed silhouette, make assumptions about the transformation of the figure.

Material: sets of counting sticks.

Game progress

AT. Look at the picture - what does it look like? (This is a lamp). The father of these children cannot repair this lamp in any way. Help him arrange the elements of the counting sticks correctly. (Perform together).

Now each of you can choose your favorite lamp.

Shows silhouettes of different types of lamps:

Name them.

Children. Floor lamp, wall lamp, chandelier, table lamp, lantern, etc.

AT. Each of you has chosen one of these silhouettes. Decide first what geometric shapes it consists of? then independently lay out the same lamp from counting sticks.

Bulb. Well done boys! What different and beautiful lamps you got! Among them there are also new - economical light bulbs. But grandparents Anya and Vanya do not change old incandescent bulbs for new energy-saving ones.

AT. Guys, why do you think? Remember how we explored the differences between an ordinary incandescent lamp and an energy-saving lamp in the project. Let's try to convince the guys' grandparents of the need to replace old light bulbs.

Game "Finish the sentence"

Target: to consolidate children's ideas about ways to save electricity; stimulate the development of logical thinking, coherent speech.

Game actions: come up with a variety of answers to the question asked, complete the sentence started by the teacher.

Material: envelope, cards with questions, unfinished sentences.

Game progress

AT. I have an envelope from my grandparents with questions.

The new energy-saving light bulb is better because... (Lights longer than a conventional incandescent bulb, saves electricity, less negative impact on the environment, etc.)

Mom and Dad replaced old light bulbs with energy-saving ones because……...

Turn off the lights when you leave the room because...

Save energy because...

You can not turn on many electrical appliances at the same time, because ...

If you do not turn off the light day and night, then ...

If all the lights in the house suddenly went out, then ...

The lights on the street stopped shining, so ... etc.

Bulb. You guys are great!

Educator. Guys, we can give this family our memos on how to handle electrical appliances, how to save electricity that you made together with your parents: “When leaving, turn off the light!”, “Save electricity!”, “Make the right choice!”, “Do not light empty rooms!”, “Do not turn on many electrical appliances at the same time!” and etc.

Convenient and safe lighting is the most important condition for the effective organization of the workplace for a school-age child. It is at the desk that he will do most of his homework, and the success of the educational process largely depends on how well the table lamp is chosen for the student.

What you should pay attention to

Table-type lamps are usually classified according to a number of criteria, including appearance, operation features, light bulb characteristics and other parameters. When choosing a table lamp, it is recommended to pay attention to such parameters as:

location;
lamp power;
luminaire dimensions, etc.

Placing and fixing fixtures

One of the main indicators is the installation method. Fixtures are fixed either to the body of the table (at the edge), or they stand on a leg - static or dynamic. The latter option is preferable because it allows you to change the direction of the light in the right direction.

The base of the luminaire must be heavy enough to prevent it from deflecting or sliding on the table. Light fixtures on a clamp are preferred, as they are more rigidly attached to the desktop.

Important! If the child is right-handed, the light source should be placed to the left of him. If left-handed, vice versa - on the right.

A very practical solution is to place the lamp next to the work area, rather than directly on the desk. As a result, additional free space appears on the table. Such lamps are installed on the floor or fixed on the wall. If such a lamp is placed in the immediate vicinity of the table, in terms of functionality, it is no different from the desktop version.

Light control method

The best option is a lamp in which the switch is located at the base or on the ceiling. The switch must have sufficient travel and not stick when pressed.

Luminaire dimensions

Lamps with fixation on the edge of the table are equipped with convenient transforming legs, which makes it possible to adjust the height of the light source, as well as the angle of the light flux. Installation height usually ranges between 20 and 100 centimeters, but longer legs are also found. The most comfortable lighting can be achieved if the leg length is at least 50 centimeters, otherwise the light will be reflected from the surface of the book (notebook) or blind the child.

The size of the lamp should be in accordance with the dimensions of the table. Such a requirement is made not only for aesthetic, but also for practical reasons. If some parts of the lighting device protrude beyond the boundaries of the table, then there is a high probability of the lamp tipping over by negligence. It should also be borne in mind that a device that is too large will not allow other useful items to be placed on the table.

The heaviest part of the lighting fixture is its base. This is done on purpose to give the table lamp stability, which improves the safety of the device. However, if the lamp needs to be moved frequently, it is better to choose a lamp with a light base.

Tripod

The most comfortable lighting is provided when the ceiling is at eye level. The tripod allows you to adjust the desired height due to the presence of folding and retractable mechanisms. There are also bendable (flexible) tripods. Flexible brackets for children are especially convenient to use, as they allow you to easily adjust the desired position of the lighting device.

Light characteristics

The main parameter that you need to focus on when choosing a lamp for a first grader (and any other user) is the quality of light. To make the right choice when buying a lamp, it is recommended to understand some of the technical nuances of lighting fixtures.

Types of lamps

Incandescent light bulbs are still the most common type of light source. Their main advantage is cheapness. However, they also have significant drawbacks, including a not too long service life, high power consumption. In addition, the use of incandescent lamps leads to overheating of the ceiling.

Fluorescent lamps have many advantages, including no overheating, long life and economy. It should be borne in mind that such a light source is characterized by color distortion, which will adversely affect the child's vision. To make the right choice, it is recommended to look at the abbreviation indicated on the product packaging. The best color reproduction when working with graphics is achieved by lamps marked with the letter C. But for reading from paper, you should choose a product that has the abbreviation LTB, since they give a warm white color.

Halogen light sources are characterized by radiation as close as possible to the natural spectrum. Halogen lamps give a soft and diffused light. Other benefits of halogen devices include long life and energy savings.

LED bulbs provide high quality light. Such light sources are equipped with power regulation, they are economical and last for many months or even years.

Note! LED lamps are offered with clocks, thermometers, calendars and other useful features.

Lamp power

If the choice fell on incandescent lamps, you should pay attention to their power. Ophthalmologists recommend choosing light sources with a power of 40 to 60 watts. It is especially important to follow this advice when it comes to a child. Using too weak or too powerful lamps will lead to poor vision (in the first case, there will be poor visibility, in the second, bright light will blind). The maximum allowable power rating is 100 watts.

Feature of LED lamps - high quality of light at low power. To provide the same level of illumination of the student's workplace as an incandescent lamp, diodes of much lower power will be required. For example, a 60-watt incandescent bulb is replaced by a 10-watt LED device.

The best option is a lamp with power control. Such a device is more expensive, but it allows you to provide more comfortable lighting. For example, when reading paper, it is better to reduce the lighting power, and when working with a computer, increase it.

Colorful temperature

An important indicator of the operation of a lighting device is color temperature. Light sources of the same power characteristics can produce different types of colors: white, daylight, cold or warm. Cold white or daylight leads to rapid fatigue of the child's eyes. It is recommended to use warm colors to illuminate the workplace. The color temperature for comfortable reading should be within 2700–3200 K, the luminous flux should be within 400–700 lm.

Note! For incandescent lamps, the concept of color temperature is not applicable, since they always give only warm light.

Shade shape and material

It is not recommended to choose table lamps with too complex shapes of shades - this is impractical. The optimal execution of the ceiling is in the form of a trapezoid. A trapezoidal plafond allows you to most effectively distribute the flow of light and create comfortable lighting for children's eyes.

The color of the ceiling should not be too bright, so as not to irritate the eyes. It is best if the lamp is in soft pastel colors.

Important! The surface of the lamp should not be glossy. Such material gives glare, so you need to choose a lighting fixture with a matte surface.

An important issue is the material from which the lamp is made. Preference should be given only to high-quality plastic. Cheap plastic will not withstand high temperatures and sooner or later will melt. You should not buy metal ceiling lamps, because it is easy to get burned on them.

Conclusion

Even the most expensive and high-quality table lamp will not replace natural light for a child. For long-term work at the desk, you need not only local, but also general light. The brightness of the general light may be small. The best option is combined lighting. In this case, the child's eyes will be less tired during classes.

Choosing a table lamp for a student is a very serious matter. And irreparable mistakes here can adversely affect the health of your child.

The emphasis should first of all be placed not on design and functionality, but on the safety of such a light source.

A good lamp can be selected according to three main components:

type of light bulb and its characteristics

tripod and ceiling

fasteners and location on the table

If the model you like passes through these parameters, then you already pay attention to other useful features and attributes - USB ports for charging gadgets, alarm clocks, etc.

At the same time, do not confuse an interior table lamp and a lamp for a student.

These are completely different products that perform different tasks.

Type of paw inside the lamp

To date, the stores offer a very rich selection of table lamps, both with simple incandescent bulbs and with LEDs.

Classical luminescent energy-saving lamps, one might say, have outlived their time.

Yes, and engage in demercurization of the premises, in case such a light bulb breaks, hunting is far from everyone.

Poisonous mercury fumes in the children's room, this is not exactly what parents want for their children.

Therefore, discard such bulbs immediately.

Ripple factor

Among other types, you need to choose those models that do not flicker. Even an ordinary Ilyich's light bulb provokes a very heavy load on the eyes.

It's one thing when such light sources hang from the ceiling. And it is quite different when they are located a few centimeters from your child.

Visually, you will not notice such a flicker of light. To check this effect right in the store, just look at the switched on lamp through the smartphone camera.

Such a simple and uncomplicated experiment will allow you to avoid mistakes when buying.

From a high-quality lamp, there will be no stripes on the screen, only one bright spot. What can not be said about cheap copies.

For example, for 60-100 watt incandescent lamps, the ripple factor reaches 14%. And sanitary standards in a residential area recommend no more than 10%.

And here the dependence is inverse. The greater the power of the lamp, the less its pulsation. But unfortunately, 150W or 200W heaters are almost impossible to buy.

And they just did fit best into the standard - 5-7%.

Therefore, from a medical point of view, look not at the savings in watts or the design of the lamp, but at what effect it has on the eyes during prolonged use.

Also, don't forget about safety. What happens if you have a power surge in your house and it hits a heated incandescent light bulb?

The explosion and destruction of glass in this case is not such a rare occurrence. But it's one thing when this happens inside a chandelier or sconce.

And it is quite another when this happens in the face of a child doing homework.

From this point of view, simple light bulbs in table lamps are no good.

Also, keep in mind that they can burn you. Yes, and they heat the body of the ceiling lamps, be healthy, at least fry the sausage.

So it turns out that the only acceptable option for today for table lamps is LED Led models.

Power

What power to choose them? Initially, ophthalmologists developed recommendations for conventional incandescent paws.

Their power should not exceed 60W.

Why exactly so many? With a higher power than 60W, the incident light is very well reflected from the white paper of notebooks, books, albums.

The child has discomfort. I want to move the notebook away or lift the lamp higher. As a result, vision is strained.

The optimal height of the light source to the table surface is 35cm.

And if there is a computer on the table, then the lamp should rise above it, and not be located on the side. Otherwise, glare cannot be avoided.

1 of 3

Do not even take into account cute and funny carapules.

But we agreed that it is not advisable to use sources in the form of incandescent bulbs. How to transfer these estimated 60W to LED models?

There are tables of correspondence of different types of lamps in relation to conventional ones. Take advantage of them.

According to these tables, LED models with a power of 6-8W will be enough for a student's desktop.

However, not all LED lights are “equally useful”. The difference in lighting efficiency at the same power can reach almost 40%.

Therefore, here they are guided primarily by such a parameter as the illumination of the working area. What it is, how it is calculated, how not to confuse lux with lumens, and what it all “eats” with, read in detail in the article below.

If the budget allows, then the ideal option would be brands with adjustable brightness and a built-in dimmer.

With the same lamp, it will be comfortable to work both with books and notebooks, and at the computer. When working with paper products, turn down the power, and when you go to the monitor, add it.

If the model is not dimmable, then when buying in a store, take a blank sheet of A4 white paper with you. And put it under the turned on lamp.

If you will not be blinded, you can safely buy such a lamp and a light bulb for it.

Glow color

Another not unimportant parameter is the color of the glow. In the working areas of offices or offices, a cold shade is preferable.

It is said to improve concentration and productivity tremendously.

However, a warm shade is safer for a child's retina.

This glow corresponds to temperatures from 2700K to 3200K.

Temperature data can always be found either on the light bulb box or on its body.

Always pay attention to color. Sometimes he can present unpleasant surprises.

The device and design of the tripod and ceiling

It is very important that the tripod is movable. Could be folded, change the angle, the direction of the glow.

And all this without moving the very base of the table lamp. That is, they put it in one place on the table, and with a movable leg you control where and how to direct the flow of light.

Models with a long tripod should be preferred. Most importantly, to maintain vision, choose the right angle of inclination so that the light does not hit your eyes.

And the more positions you have in which you can fix the table lamp, the better. Because believe me, writing requires one tripod position, while drawing requires another.

The head itself or the ceiling should also bend and spin.

Wherein don't choose models:

whose plafonds have a bright coloring

They will distract attention and play the role of an irritant to the eyes. The best color is neutral (black, white) or dark green.

with not deep ceilings

If we are not talking about flat LED options, but about cone shades where pear-shaped bulbs are hidden, then the bulb itself should not be allowed to peek over the edges.

It must always be completely recessed inside the housing.

with a diffuser in the form of separate large dots on the panel

There are more and more desktop options with non-removable and non-replaceable LED panels. But if some of them are able to give an even luminous flux, then here are the others, they shine, as it were, with separate bright points.

Also count the number of LEDs in these sockets. The recommended number is at least 12 pieces.

Although everything may depend on their power. However, with a larger amount, the light will be more uniform.

made of heat-resistant material

Although the LEDs do not heat up, do not forget that this is still an electric device. And no matter how expensive the model is, closures are still theoretically possible.
