yesterday I went to the petstore to look at supplementary heat source for my crabs, as it is winter here and starting to get cold overnight. My tat gets down to 22*C (72*F) overnight.
I was looking at lights and I asked the guy if I can get a hood-type thing with multiple fittings so I can have a night glo or infra-red for night and a sun-glo for daytime. He said that hoods aren't usually used for providing heat as the long fluorescent lights don't generate it well, so you have to use a clamp-lamp type of thing. He said there aren't any lamps available used for heat that have multiple fittings in them... Is this true guys? It just sounds silly to me b/c it's reasonable to not want to have to manually unscrew your night bulb every morning and constantly have to change them.

He said if I wanted the lights on a timer I would need to buy multiple clamp-lamps, which is pricey. I swear I've heard people on here say they have heat lights in multiple-fitting hoods set to automatically go on and off at the right times...

I would like to have three fittings if possible, so I can use a choice of moon-glo or infra-red at night, and something with UVB in the daytime.
Also, do clamp-lamps lose much of their effectiveness if you sit the lamp atop a glass lid (does the glass block much of the heat coming in)?
-Thanks
