i'm looking for an older thread i cant find in the forum search.
It was about some people's skin injured by a HQI lamp with missing UV filter. Anyone knows where to find it?
I have had trouble finding some of older topics that I have wanted to re-look at too.
Anyway, I'm not sure if you can get a sunburn, but I have seen furnature get "sun-bleached" from metal halide lamps. Designer spec'ed them for a furnature showroom - destroyed all the furnature!
I remember see the news clip.
it was in a school gym. the people a sat under the lamp for like six hours or something.
diffrent store but my wife got burned once.
she found a uv/metel halide lamp at goodwill took it home and put her face infront of it for just two or three min. she look like a lobster in the middle of winter. it was really funny looken but scary at the same time. shes got more frekls now.
there was a thread here about the people in the school gym.
I wanted to take the text and post it to a diy- video beamer forum, those guys take the outer glass of their metal halide lamps off to optimize whatever.

Look at
this document . And
this one and
this one . Note that a code change in the 2005 code requires the use of enclosed fixtures or open fixtures with type "O" lamps to address this problem.
