It has 4 ft. bulbs in it. Maybe it depends on the bulb. In there now are Ultralumes 5000K. I was not happy to first hear the advise. I found it to be a kind of a hex. I'm always wondering what could be the culprit other than my own folly when I look through last nights take in the darkroom. Every time i then see some prints which are inexplicably too dark with I believe is a fact of darkroom experience in my 35 years in the darkroom I try to figure out what could have possessed be to be so dumb: variable drydown, compressed curves, glowing flourescent bulbs. I'll take anything. Staring at the bulbs on the ceiling of my darkroom as i flicked them off and on sure got the attention of the people hanging around my studio. You can drive yourself crazy with that stuff wondering if it is your eyes or the bulbs themselves. Mark
