There were reports that some emit significant levels of UV light and if you use them as a desk or bedside lamp with an exposed globe there are cancer concerns. Many that I see now have a transparent material shielding the globe which is supposed to screen out UV. It seems as though it is now getting hard to find UV emiting halogen lamps - if this report I found online is to be believed:StudioTan wrote:MickGael wrote:StudioTan,
Gotta ask - does the name indicate you are a Zappa fan?Yes. But it seemed to fit because of my extended time in studio. I wonder if you can get a tan from Halogens if you stay under them long enough!

Halogen lamps and UV
I want to comment on previous discussion about halogen down-lights and their high UV content (see page 109, November 2004 issue). I needed some UV to harden some plastic. I went to the major hardware retailer and could only find covered dichroic lamps in stock.
Single 12V 50W halogen lamps were labelled as zero UV. I purchased a 240V 150W halogen lamp but when tested, zero UV was present. Amazed at this, I eventually found an old uncovered dichroic lamp mounted in the ceiling and it proved to have significant UV output. The manufacturers must have changed the glass type to eliminate the UV. The moral of this story is that things change.
Looks like the term Studio Tan is here to stay.
