We all know about halogen light bulbs and how much more efficient they are than regular light bulbs, but they aren't the end-all be-all of lighting solutions. In fact, there's a new bulb out there that make halogens look downright irresponsible.
This LED light bulb, designed by Frog Design, will last you for a whopping 30 years before burning out, using a fraction of the energy of normal bulbs. It's shaped like a regular old lightbulb, and it plugs into any regular light socket. Whether or not the light is a warm glow or a harsh white light is yet to be seen, but if it's the former, get ready to never change a light bulb again.
