I added a diy 50W LED that shines on the white ceiling of my office room. The diffuse bounced light feels closer to sunlight. It’s wonderful for those darker days.
Make sure to get a high-CRI led, that’s what really makes the difference in my opinion. Cheap leds will have a narrow frequency band, high CRI is what makes the reflected light feel more real.
I use a cpu heatsink with silent fan to keep the led cool.

- wincy 4y agoFascinating, I’d be interested in seeing what ten or even twenty of these could do to a room. I’m curious how many lux I could get in a room without tripping a breaker. The added benefit is I don’t have to run a space heater!
- andruby 4y agoHonestly, a single 50W led is more than enough for an office sized room. That’s not a lot of heat. We’ve got 16A circuits at 220V here, so you could do about 70 of those before tripping a breaker :D
- wheels 4y ago> Honestly, a single 50W led is more than enough for an office sized room. You're talking about something very different than the original poster then. They mentioned something more in the 400 watt range. I have around 70 watts of LEDs (split between 7 bulbs) in my small office (7 square meters), and am considering boosting that significantly. 50 watts I would put in the range of "normal bright lighting" (it's approximately the equivalent of one halogen floor lamp). 400 watts gets into "trying to simulate sunlight for therapeutic reasons"-territory.
