Since I only need one, I don't mind paying a premium for it.

I want a low voltage light with a warm color.

I was looking at LED, but I could not find a light fixture made specifically for a shower. I only see that they are rated for moist areas, which I fear would wear prematurely in my wifes 'steam room' shower sessions. Of course, I would want this completely water tight.

Does anyone have a good product that they have had good luck with?

Another note -- this would come in contact with attic insulation.
