Multitasking LED Lightbulb Provides Ambient Light, Music
The eTiger Cosmic lightbulb adds music to its environmental offerings
You already knew that LED lightbulbs had advantages over incandescents and fluorescents. They last longer — up to 30 times longer — than their competition, and draw significantly less power while doing so. Scientists even invented an LED that was power-negative, meaning that in a hot enough environment it drew more power from the air than it used to create light.
