Could it be that the Malkoff drop-in causes this? It is heavier than a SF lamp or the P60L and it doesn't have a spring to soften the impact as it is trapped between the window and the metal of the light.

That's an interesting thought. When I get my new bezel I'll try to replicate the same situation with a P60 in the light - just kidding!
I was thinking about the circumstances of the "accident" last night. I'm no physicist, but say I'm going 15mph. Of course the flashlight is also traveling at the the same speed. Even though it's not impacting on a surface perpendicular to the direction of travel, the force with which it impacts is significant. I had at first thought that the major damage happened when the light tumbled after impact, but it now seems obvious that it probably happened on the original impact. It would be interesting to do some drops with a P60 and an M60 (onto a cushioned surface) and see how the extra weight in the head affects how it lands. Gravity being a constant, it would drop at the same rate of speed, but maybe a slightly head-heavy light dropped parallel to the ground would be more apt to land bezel down than a less head-heavy light dropped from the same distance. Just some random thoughts...In any event, I don't think I'll be using a dropin other than the M60.
