However, you claim to have made a box with 16,000 lumens. There is a difference in units between lumens and lux. Lux is actually lumens/square meter. If you indeed have a 16,000 lumens light box, and the box is .5 square meters, you will actually have a 32,000 lux light exposure. This might actually be too high a light dose and may cause problems. Did I interpret your statements correctly? - Donavin Jason,
