Confused on terrarium lighting hoods

[Paul Mc]

OK, so I'm really dumb when it comes to lights though somehow I managed to figure out a good lighting system for all my tropicals in the basement. But that took years to figure out and I did not have all of you wonderful people.

I just bought the Zoo Med 12x12x18 terrarium and am now looking for lighting. I've seen all sorts of lights for use with terrariums ranging from hoods, hanging light bars to dome lamp fixtures.

My concern is that most of these fixtures are for giving ultraviolet light to the animals inside the terrarium for proper health, and many bulbs are for heat purposes as well.

Zoo Med's 12" hood says that it includes a built-in reflector and socket for heat or UVB lamps. Are these the right kind of bulbs to use for growing orchids in it? Can I use a better substitute inside of this fixture?

I think I'd really like to keep with the hood idea as it will help to keep some humidity inside, plus it would be nice if the hood actually fit - thus looking at one Zoo Med makes.
