Well, the blue incandescent I had didn't stimulate plant growth, and at the time, I didn't know you could get them in full sprectum light...

I'm wondering if the low watt, blue incandescents that do provide a full colour sprectrum will give off much heat? Either way, looks like I should replace my 6500K's with these...? I'll just keep the 6500K's for my red backed salamanders because they do not tolerate heat of any kind, they like it cool (60-70F).

I really appreciate all the info! (You should post your name, so people arn;t calling you by frog frogs name! )

EDIT: Every incandescent blue or black (I've been always interested in a black for occasional night viewing) I look up is 15watt or more, and is listed as a "heat lamp". Mind you, I guess a 15 watt incandescent wouldn't burn THAT much more energy than an 11 watt CFL.
