| RE: Mercury Vapor Lamps
i use one for my mertens water monitor, it gives him a nice basking heat when he comes out of the water (not very often mind you)
I find it good, but then again its the only lizard i have so i dont really have much to compare it to
oh an by the way you cant use them on a thermostat, so this makes them NOT suitable for small enclosures or enclosures without alot of air circulation, mine is just on a 24 hour timer!!
