MUCH SNIPPED

There have been a couple of incidents around here (Portland / Lake
Oswego, OR) recently where Halide lights in school gymnasiums (ok
gymnasia to the Latin /reek scholars) had cracked outer coatings.
The lights emitted a_LOT_ of bad UV stuff; several students and
teachers apparently suffered serious and permanent eye damage. The
exposure was over a several month period, AIUI, and there was no
obvious indicator that the bulb outer coatings were cracked.

Me, I'd stay away from them in the home / garage / workshop setting.

And I say that living in an area where from about now to mid April
where our "daylight" is usually a cold wet grey cloudy dim mess. I
like "bright", but won't take unnecessary risks.




Those metal halides emit a LOT of UV,and are not filtered.
They will fade any colored items,and are bad for your eyesight if not
filtered.They also can explode and shower you with broken glass shards.
