However, there are different types of designs available, including USB-powered desk lights, clamp stand desk lights, dimming desk lights, and so on. The variety of deck lights can often make the users wonder about the best-suited one for themselves.

A table lamp product specification involves many technical terms and numerical values, which is difficult to comprehend without the proper knowledge about lighting. So many users often tend to ignore it and just focus on design or operability. We want to start by explaining the basic points that you should consider when choosing a table lamp for yourself.
Recently, LED table lamps are becoming increasingly popular as they produce less heat and help in energy conservation while lasting for a long period of time. Although the price of table lamps has decreased greatly since LED desk lights have come into play, fluorescent desk lights are still the cheapest lights in the market and are often a popular choice.
You will see many technical terms in the product specification of table lamps, but only four of those are of major importance to you: lm, lx, Ra, and K. We have simplified them all in the sections below, so keep reading!
As a result, lumen (lm), the measuring unit for LED lights, represents the amount of light (total luminous flux) radiated from the light source in all directions. As the value of lm increases, so does the brightness of the light source. For your reference, a 100 W light bulb equals 1500 - 1700 lumens. For example, you'll need 5000 lumens for 250 square feet.
The brightness of the area when a desk light is used is known as illuminance and is displayed in lux (lx) units. You will find that even with the same amount of illuminance, space's brightness decreases as the distance between the desk light and the brightened space increases.
For example, if you are looking for a table lamp to read, then 500 lx brightness is required for comfortable reading, which is also the ideal ranging from 500-800 lx.
The color temperature is expressed in Kelvin (K); simply, it measures the temperature of the light. The lower the value of K, the warmer the tone of light color can be, much like that of candlelight. On the other hand, a higher K value results in whitish and clear light.
It all depends on your condition/preference; if you have a sunny bright room, you'll most probably prefer a dimmer light comparatively. So, look for 2700-3000k lights that have a warm brown-yellowish tone. For those who prefer very bright tones, look for 5700-6500k. The average used by the household is between 2700-4000k.
The maximum value tends to be 100. So, if your table light comes with a Ra of 80 or more, then it will be considered as a highly natural light source with high color rendering properties to cause less eye fatigue.
You also have the option to choose the installation method and the power supply type of the desk light, depending on the environment. So, make sure that you check the space and usage purpose before selecting a desk light for yourself.
If you want a table lamp but still don’t want it to occupy a lot of desk space, then a clamp-type table lamp is the best choice for you. This type gets hooked at the corner of the table, as shown in the image above.
However, make sure that you have enough space to attach your lamp, or else you won’t be able to install your light on to the desk. So, people who want to keep their table tidy or have other things to keep, say, a laptop and monitor together, or even video editors, would like to prefer such table lamps.
Another type of table lamp is USB-powered that can be attached to a laptop or plugged into an electrical outlet with an adapter's help. However, the brightness and illuminance of the table lamp will differ depending on the power output source.
If you use a laptop to power the desk light, it will produce less. If you use an AC adaptor and electrical outlet to power it, it will produce more powerful light. It can also be easily transported and used anywhere, which makes it highly portable and useful.
Also, a desk light whose angle can be adjusted will make it easier to brighten a particular area that requires more light so that you can work comfortably when you are surrounded by people too.
