I am trying to decide whether to purchase halogen light fixtures for the bathroom or stick with conventional incandescent fixtures. I understand that most halogen fixtures require a 110-12V transformer to be installed, either hardwired or attached to the electrical box. As these are apt to break down and get hot, I have 2 conerns: 1) replcaing the transformer will require breaking away the drywall around the electrical box and 2) transformers tend to get warm and I am concerned if this can be a hazard.

I'd appreciate any advice or experience with halogen fixtures. They do shed more light and offer a variety of more contemporary lighting styles, hence my interest.
