If you are thinking about using low voltage halogen lights consider the following two problems, heat and noise. The ballast get dam hot and you will need gloves to move them plus many of the ballasts in the transformers start buzzzzzzzzing and buzzzzing. I have seen staff at 4 museums and galleries being driven nuts by the problem of buzzing ballasts. Why cant someone develop a compact fluorescent with a good uv filter. I realize that it could not be dimmed but it would still answer many of my needs. -- Lee Boyko Sooke Region Museum [log in to unmask]
