The questions are, essentially, are they suitable for garage

I like them.

UV content is less than that in a similar amount of daylight. Just
don't use them if the outer bulb gets broken - the bulb blocks nasty
shortwave UV and UVB that the arc makes a little bit of.

Use in suitable fully enclosed fixtures rated for use with these bulbs,
unless the bulb package says that the bulb is suitable for use in open
fixtures. Every few blue moons somewhere a metal halide bulb that is not
of the "protected" type (suitable for use in open fixtures) explodes.
