Which table lamp should you choose?

Question

Workplace

Good afternoon.
The question arose about choosing a table lamp for the workplace.
From bad lighting, the eyes are already starting to ache.
What are the most eye-pleasing lamps on the market today?
What is the difference for eyes in led and fluorescent?
If somewhere there has already been a detailed answer, I will be very happy with the link.
Thanks in advance.

I'll try to write a short summary.
The main characteristics, in my opinion: color temperature, color rendering index and flicker depth.
For relaxation, the color is better warm (2700-3000K), for work it is colder (4000-5000K). But here everything is individual.
Color rendering index - the higher the better (but the Chinese cheat a lot with it).
Flicker depth - ideally - 0.
Incandescent lamps (better than halogens): "color" is warm, color rendering index is close to 100%, flickering by 20-25 percent.
With the rest, everything is much worse, since it strongly depends on the manufacturer and even specific lamps.
Compact fluorescent lamps come in any temperature, but I have not seen a color rendering index above 80%. Flicker depends on the ballast. Electronic ballast, even for Chinese lamps, usually flickers less than an incandescent lamp, but electromagnetic, like many U-shaped table lamps, is 50%.
LEDs also formally come in different temperatures, but in reality it is a blue LED with a yellow phosphor. The result is a low color rendering index. Flickering depends on the specific instance. Even one manufacturer can have completely different models from those that do not flicker at all to those that rectify alternating current on the lighting LEDs themselves and shine for half a period, but not for half a period.
Personally, I prefer 4000K linear fluorescent lamps with >90% color rendering index and good quality ECG with <3% flicker depth.
