Hi, Some days ago I asked if someone could tell me how to know the real temperature of a lightbox. I didn´t realize I could use my X-RITE DTP-94 colorimeter to measure temperature and luminance. JESSOPS LP45 has two lamps in the corners. Temperature over the lamp is 5050 ºK and drops to the center of the lightbox to 4300 ºK. Luminance is 1080 cd/m2 but evenness is disgusting all over the surface.
