This wooden light bulb by Ryosuke Fukusada - modern LED device to create what appears to be a solid piece of wood shaped like a light bulb but which actually radiates light. The inside of the wood is chipped out until light can shine through.
For years, no new light bulbs? Now, we get a new light bulb once a month it seems. Panasonic LED mimics the filaments in a traditional bulb, and yet it uses a fraction of the power, can be switched on and off times and has instant 'on'. via wired
