How much light is too much light?
Check this answer.
For computer work you don't want too much light, as that could cause glare on the screen. Say 200-300 lux ; less for gaming or dicking around on social media, more for actual work.
For paperwork you need proper lighting, 300-500 lux.
For electronics, if you want to read the value on a SMD resistor with 50 years old eyes, count 500-1000 lux.

Lux are lumen per square meter, so if you had a fixture that throws all the 1000 lumen of a lightbulb onto one square meter of desk space then you'd get 1000 lux. In practice a significant proportion of the light goes elsewhere, light beams aren't perfect, and the inverse square law says when the light is twice as far, its intensity is spread over 4x the surface, which means 4x less lux.
Inverse square law means you can easily get much higher levels of illumination on a small area with a desk lamp and a spot bulb (because it's close to the desk) than with a powerful ceiling panel. However, a desk lamp will make hard shadows which are annoying when doing electronic work.
Now, since you have several different needs, which require different levels of illumination, it means of you use only one light it has to be dimmable.
If it is dimmable, due to Kruithof curve (see link at beginning of post) it has to be variable CCT or else it will suck.
Also you need high CRI even if you don't know it yet ;)
Simple solution:
This is what I did at home since I couldn't find any LED panels that suited my requirements. They're all either CRI 80 which is garbage, or horrendously expensive.
Aluminium profile like this one which can take 2 LED strips, with clear diffuser that you can frost lightly with steel wool. This is a wide profile, which allows two LED strips mounted on the inside.

24V 4000K CRI95 28.8W/m LED strip ; you can also use 5000K if you want, but their 4000K is really nice.
24V variable CCT 2400K-5500K 28.8W/m LED strip
Dimmer and FUT092 remote (note: this one doesn't flicker, PWM is at 5kHz)
24V supply
A 2m long profile fits nicely above a desk, and these look quite slick. You can suspend this from your ceiling at a height of your choosing. Inside this profile you put 2x 2m LED strips at 28.8W/m each, or 115W. It's important to put the different color strips close together inside the same profile so the variable color temperature light behaves as a single light source; if you use two profiles with different CCTs you'll get colored shadows. If you make two lights, a 24V 10A power supply like Meanwell XLG/ELG-240-24 will work fine.
Use the RGB controller. On the 2400K/5500K strip, connect 2400K to output &quot;RED&quot;, 5500K to output &quot;BLUE&quot;, and connect the 4000K strip to output &quot;GREEN&quot;.
Then you can use the remote to set intensity and color temperature.
Now you might say, &quot;what? you're using the RGB outputs to control color temperature?&quot;
All LED dimmers which control color temperature have the same problem: constant output power. If you set the color temperature to &quot;warm&quot; or &quot;cold&quot; you get 100% power on the &quot;warm&quot; LEDs or the &quot;cold&quot; LEDs. But if you set in the middle of the range, you only get 50% power on &quot;warm&quot; and 50% power on &quot;cold&quot;. The sum is always 100%. So you can't turn on both LEDs at full power at the same time, which is annoying. If you use the RGB dimmer instead, you can set both LED channels to full power at the same time. This is purely a software issue, and it is much simpler to do it that way than to reprogram the proprietary dimmer firmware...
Additionally, the dual color temperature LED strips all have the same problem: to respect the Kruithof curve and get a light that feels good at all color temperatures, you need about 3x more &quot;cold white&quot; LEDs than &quot;warm white&quot; LEDs. But these strips have the same number of both. Underpowered &quot;cold&quot; (4000K-5000K) light feels icky, so that's why I'm recommending one color changing strip, and one single color 4000K-5000K strip to boost it.
With this setup, using the RGB wheel:
&quot;Red&quot; gives a 14W, very warm 2400K light which is really cozy. At this CCT it doesn't need much power. 2 meters of the strip I mentioned will be just right.
&quot;Green&quot; gives almost 60W of 4000K LEDs which is great for office and electronics work.
And if you slide your finger a bit more towards &quot;Blue&quot; then the 5000K LEDs in the dual color strip will also turn on, which gives a bit more power.
I really like the result, and the color rendition on these Auxma strips is beautiful. Unlike cheap LEDs there is no ugly greenish tint.
