I was researching how to make my photocopies with my copy stand a lot better. I started researching color temperature, and many people helped me find a decent set of bulbs. However, I notice light bulbs also come with another feature called "lumens." I tried researching this subject, but it seems to go into "wavelengths," physics, and so much other scientific jargon. I think I understand the basics of lumens, but do I? If I understand correctly, lumens have something to do with brightness. Is that right? If a bulb has too many lumens, it can cause hotspots, washouts, and whatnot on photographs. Is that right? I was using 75W bulbs on a document, and I noticed the text fading out. However, when I went to 60W bulbs, the text was more sharp. I had experimented with the timer to make sure it wasn't camera shake. Does anyone know if too many lumens cause too much brightness in photographs?
