looking at the specs from 1000bulbs.com, the merc-vapors had a color temp of between 3200K-5700K, depending on particular bulb (suitable more for vegging) ... the lumens were decent, too, BUT ... there may be a heat issue with them ... not sure, but I think I've heard that somewhere before ... that's all I can tell ya ...
