Underwriters Laboratory requires some sort of sheilding, although in
some cases it is wire mesh rather than glass. (In case of "Non-passive
Failure" - my favorite techno term, thanks to GE.) This covers 99% of
North American instalations and equipment.

This UV scare has been going on for well over ten years. There was an
experiment in Italy where they baked some hairless mice with unsheilded
lamps. Gee, they developed skin problems. The press went wild....
***You get more UV walking to your car than from sitting under halogen
lamps.***

Note to JS: As you noticed lighting is not cut and dried, there are
many options and the best solution depends on the details of your
situation. Energy, quality, dimming, start-up, first costs, space,
style, your age!, type of work....

Good Luck

The problem is usually not the amount of UV coming out of the lamp; it's not
knowing that you are being exposed to it and taking proper precautions.
When people switch on a desk lamp, they don't expect to get "sunburned" from
the light.
