I gotta' ask: C'mon, has anyone really had that much trouble with the fragility of incandescent bulbs? To put it another way: is this a real problem or a made-up problem to justify going out and buying some new stuff to try (not that there's anything wrong with that )?
I have had problems with the mini mag lite's bulbs' frailty. Don't get me wrong, I have owned many (about a dozen) mag lites including quite a few mini's. The problem that I noticed was with the mini's as I haven't dropped a bigger one. Whenever I accidentally drop a mini from even as low as 2-3 feet, I find that most of the time the bulb shatters and most of the time, the spare bulb in the tail cap shatters too, leaving me up the creak.
