I've been searching the web and eBay etc and can't seem to find a clap lamp. I admit I've only ever really seen it on The Simpsons, but surely they exist? Yes i'm to lazy to reach over and use a switch, and the clapping seems like a much easier option.
The closest i can find is this - http://www.ebay.com.au/itm/Novelty-Voice-Activated-LED-Night… But i would much rather buy something approved by Australian standards with an Australia plug.
The thing that was parodied in the Simpsons was called the clapper

It was a real device that was sold in the 80's.
Yes they've gone out of fashion but with an Arduino you can make your own..
Nowadays though you can get smart color-changing LED lightbulbs that can receive bluetooth and wifi commands from a smartphone and smartwatch. e.g Belkin WeMo, Phillips Hue and so on. I think this is the safest option if you don't want to dabble with soldering and possibly zapping yourself.
