A bar I visited the other day had old-school Edison bulbs hanging from the ceiling, and I noticed that in several of them, the filament was vibrating. And by vibrating I mean vibrating big time — swinging back and forth a full inch or so inside the bulb multiple times a second. The bartender didn't seem to know what caused it, but seemed to think it wasn't uncommon. Any idea? [more inside]
Why do these light bulbs keep dying? [more inside]
Why is this lightbulb flickering? [more inside]
Why do my lightbulbs burn out so fast?! [more inside]
My family's been wanting to upgrade to compact florescent for years, but we've always found they burn out quickly thanks to our flaky power surges. Would dimmable bulbs be helpful, or is there some sort of inexpensive power conditioning that can be added to light sockets? [more inside]
I just replaced a burned out bulb in my overhead kitchen fixture. The bulb that burned out was a 60 watter. I only had a 100 watter on hand. I know I'm hastening fossil fuel depletion, but am I also causing a fire risk? What about ignoring the wattage recomendations in favor of higher watts in table lamps?
