its in a residential home. and incase there's any confusion as to how the closet looks, its similar to this diagram |_`_`_`_`_`_`|

Thats a horrible diagram but you get the idea. imagine that the "_" are the front of the closet (2 sliding mirror doors) and the " `" being the wall.

I guess its a standard closet that insn't more of a square shape, more like the ones that aren't too deep in, but run along the wall more. Am I making sense?

Second.. forget about the budget I mentioned. I just want specs on which lights are preferable. Venting will be the biggest issue I run into I'm guessing. I have a hepa-air filter in my room for my snake that accually keeps the room reletively fresh. Secrecy isn't too much of an issue, only would become an issue if someone snuck into my back yard and started peeking through my bedroom window. Not likely. I can also run a squirell fan leading outside the closet if neccesarry.
