It would seem that even if I have a two bulb setup that I would want to have 2 x 6500K and not use the 10,000K at all. Does the 10,000 look better to our eyes or something? _______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/gsas-member
