Yeah it’s truly astonishing how bright the sun is when you start trying to recreate it at home. But my room is brighter inside than an overcast winter day outside! That was my goal, and it’s substantially improved my mood. I’d do a write up but my strategy has been “keep buying lights until it feels bright enough and distribute them around the room”. I should probably get a real lux meter I’ve just been using my phone which seems a bit off.
