A new type of filament bulb

This is an LED filament bulb. That's an oddity. A filament is normally a wire that gets hot and glows. The wire is said to be incandescent. Here, LEDs are produced in series along a stem to look like a filament. This is how it gets to be only 8Watts. see https://en.wikipedia.org/wiki/LED_filament
