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.

Tech innovator eTiger has added another feature to LED lighting: ambient sound. The e-Tiger Cosmic LED lightbulb comes with a speaker and a bluetooth chip that both draw their power from the standard fixture connection.
