Broken bulbs happen, and I’ve even heard of bulbs falling out of the screw threads after a while. I like the EaseOut bulb extractor, but I figure most Toolmongers will just use a pair of pliers if they can reach the light socket. If the broken bulb is out of reach, though, you might want to pick up this long-reach broken-bulb extractor from Unger.
The metal fork punches into the remaining part of the bulb, which will probably result in falling glass — your guess is as good as mine as to whether the little plastic cup will catch it. But for $10 this could complete your vaulted-ceiling maintenance kit and save you the cost and space of a really big ladder.
