- This is totally true, and totally misleading. Your bit about "Without
- a UV filter" is the heart of the problem. There are no such things
- as desk lamps without UV filters in the United States of America. Safety
- regulations have required shields on halogen desk lamps for years, perhaps
- forever. You are talking about a safety problem which does not exist.
-
- Fearmongering at its very worst; a half truth turned into a whole lie.
-
- Unless you remove the UV shield from your desk lamp, there is no danger
- from them. Take a look at a theater stage some time. They aften use
- 100s of Halogen lamps which are typically between 500-2000 watts (10 to
- 40 times a powerful as your punny desk lamp). If what you said was
- true, then actors would be sun burnt after every show. They are
- not because their Halogens, like your desk lamp, is UV shielded. Any
- glass or plastic cover will do it.
