If you thought mousetraps were tough, try building a better lightbulb.
Just in time for Earth Day, a team of American inventors have created a bizarre-looking new bulb that turns illumination on its ear, using light-emitting diodes (LEDs) clustered within a conventionally shaped bulb for illumination rather than filaments or fluorescent tubes.
It will never end up in a landfill. It will not poison anybody. It may be the light of the future, hopes Switch Lighting CFO Brett Sharenow.
