Generally they should not do this. However, make sure you don't touch
the glass when installing the new bulbs (wear gloves or install them
using the box etc). Leaving finger print oil on the glass may increase
the risk of explosion.

Surely in this type of bulb the outer envelope that you touch is quite
separate from the quartz glass envelope of the bulb itself. So it
*isn't* necessary to avoid touching the bulb as it is with the linear
quartz glass bulbs in spotlights where you can touch the actual quartz
glass.

If you read the instructions supplied with most of them, it still

Well I tried very hard with the first few I used and I could see no
trace of any information on them indicating that one shouldn't touch
the outside.

applies. The ones with the outer glass envelope (like GU10s) are
supposed to contain the explosion (should it occur), but you can still
get some softening of the outer glass from contamination.

(The linear halogen jobbies are much worse in this respect though)
