Do I need diffuser for SAD light box? Answered
Most of light boxes I've seen does not seem to have diffuser on them. I guess using UVless leds won't cause problem without diffuser, but doesn't looking at LEDs without diffuser still cause eye problems?
IF I do need one, what kind of diffusing method should I use? ALso, does diffusing decrease light intensity? I would like to create 10,000 lux.
