I found this neat product call Solux Daylight Bulb. They come in 4,700K which is high for halogen.

These would be perfect for my track lights in the apt. I have a spotlight pointing at my tank which is a regular halogen bulb. I think a daylight replacement would be perfect not only above the tank but in the computer room and kitchen as well. Daylight would look much better than the existing yellowish halogen that I have.

Anyone seen them or know where I can buy them or have any experiences or comments?
