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.

MH bulbs give off a lot more UV when the are warming up, I've seen
warnings not to look directly at the bulb when it is warming up.

Given that until it lights up, there isn't anything but an arc inside,
this seems quite wise advice.
