I haven’t really figured out a good way to diffuse the 250w corn bulb, its blinding to look at and it’s absolutely massive. Maybe I could use ABS and 3D print a translucent shroud and mounting bracket for it.
I had another 100W corn bulb that didn’t use a fan and it burned out after about a year.
I’ll be honest right now I’m in a transition period of moving rooms so I’ll often just spend 30 minutes in there in the morning, although last year I spent 8 hours a day in there. It really helped me during the big snowstorm the Midwest US had recently. I just bought cheap 200W equivalent LED bulbs until I got to the full 28, because that was super easy, then I’ve started experimenting.
In winter time when the sun is shining directly into the window that’s still brighter, but that happened maybe a dozen times over the last 80 days, even with a south facing window. This winter was super dreary.
Sorry I’m rambling, but Maybe at some point I’ll worry about CRIs but this was mostly an experiment. It has definitely helped but if you like indoor lighting you probably already know that.
I might comment wattage and lux if I can, couple days.
