[QUOTE="WayneF, post: 194384, member: 12496"] Those lamps are interesting, in that they are marked 65 watts, but specs say 45 watts. No temperature, just says "white". What you actually want to see is the CRI rating. Fluorescents have a ragged spectrum, a few lines, not continuous. CRI is a rating number that compares their response of several test colors, as compared to incandescent. Incandescent may be orange, but it is easily corrected, because it is continuous, all the colors are there. Fluorescents have empty bands, simply cannot illuminate some colors correctly. So, you want a CRI rating of about 90 (incandescent is CRI 100). One beauty of a light tent is the subjects are fixed, static, and you can easily use 100 watts and exposures of a second or two, no big deal. Long exposure simply does not matter. Dimmers probably won't work on CFL. Even if it does, it will shift colors seriously. [/QUOTE]
