This has happened twice in the last week in two separate fixtures on two separate circuits. In one case 2 bulbs in a 2 bulb fixture "flashed" and burned out when the switch was turned on. In the other case 2 out of 4 bulbs "flashed" and burned out when the switch was turned on. In both cases, replacing the bulbs relieved the issue. It seems extremely unlikely that it is just the bulbs, but it is also hard to imagine that it is the switch. My best guess is some kind of voltage spike, but why would that happen when you turn the switch on?
Any ideas?
