Here is some information, in case you haven't noticed yet, the new style light bulbs are extremely durable. The old style incadessant bulbs were somewhat fragle and would burn out with rough handeling, even the 'Rough Service' bulbs were only a little better. The new style bulbs (that look like a spiral) are extremely durable and will endure rough handeling. When I was getting resdy to have my attic insulated I needed to add some rafters in the celling and some of the fixtures were on trusses where I was adding the extra rafters. With conventional bulbs one hammer blow on the truss and the conventional bulb would burn out, but with the new style I could drive in nails right next to the fixture and the bulb was OK. Some of them would vibrate loose and I just screwed them back in, of course if one vibrated all the way out it would fall to the floor and shatter. I use them in 'clamp lights' when I'm working on a car and I can knock them around with no trouble, but a convertional bulb would never survive for more than just a little bumping.
