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.
