Not only that, but if the outer glass bulb breaks, but the inner
gas discharge element doesn't it will generate some VERY SERIOUS
UV radiation. Probably enough to kill everything in your tank
and cause you some serious burns. There are lots of warnings
about this inthe lighting catalogs; they even make special bulbs
that turn themselves off if the outer glass jacket is broken.
