Recently I found an article by a fellow s.a.d sufferer who built his own light system trying to mimic sunlight. First he rigged his system to have 30,000 lumens, then upgraded it to be 90,000 lumens!!
His goal was to get as close to outside daylight as possible, which is around 100,000 lux on a bright day.
By comparison to his set up, one of the brightest full spectrum bulbs available on amazon, an Alzo Digital 45 watt CFL, produces 2800 lumens. And that’s the brightest one I could find in all my years of searching!
This guy’s system is equivalent to using 32 of these bulbs!
I had been using a tree lamp that has 5 of these Alzo bulbs for a total of 14,000 lumens. On top of that, I also sit in front of three 10,000 lux s.a.d. lightboxes at once in the winter & even in summer for extra light. Family, friends, and even doctors were thinking I was nuts, but I felt better as I kept increasing the light.
After reading this guy’s article, I may need to step up my lumen game to feel even better!
