This is a beautiful vintage Edison bulb with a spectacular spiral filament. It is perfect for a Steampunk lamp. The bulb is HUGE, yet it fits a standard E26 socket. To really appreciate the beauty of the spiral filament, the bulb should be used with a dimmer. I am sure it will last much longer when operated at less than full brightness.

Still kicking! It's a nice bulb. Given its cost, I put a diode on the base to extend its life. Makes a nice piece all on its own.
