Lightless bulb?

[omnibus2]

I am keeping my corn snake in my bedroom, and I use a light bulb for it. I would really appreciate a good light bulb that doesn't make any light so it doesn't disturb me at night. I use infrared bulbs, and they do not disturb the snake, but emit a red light which is quite visible. I know of ceramic heaters, but I wouldn't prefer one. Does anybody know any specific good bulbs? Thanks a lot.

I could be wrong but I think any light or thing that heats up humans can see.....sucks to be the superior being doesn't it. haha
