Nope... they are not even really halides, Mercury Vapor lamps (Iwasaki), rated at 6500K, but by being pushed with magnetic ballasts their actual output is somewhere around 7600K. I was expecting to see a lot more yellow tint from the lower color temp, but I'm very pleased so far, nice and crisp, just the slightest hint of yellow.

Angel is right that is a lousy pic, taken and posted while half asleep, I swear it looked a lot better to me last night. But they've been running since 10am this morning, and all I can say is WOW! Everything is responding fantastically, haven't seen things so puffed up and polyps are extended further than we've ever seen, even the shrooms that were always just sort of laying around are standing tall and pimpled up.
