I was about to write that companies are exagerrating with all these new super-saving-super-green lightbulbs, but… hmm, this one might not be so bad.

Dubbed the Motionbulb, it has a built-in motion detector. My first reaction was “Come on, can’t you stretch your hand a little bit and find the light switch? You should know where they are, after all it’s your house!”, but now that I think about it… there are a few places where I’d like one of these; for example I have a long hallway with the switch on one side, but my bedroom is on the other end, so I end up bumping my feet into a chair or the cat if it’s dark.

So how does it actually work? It uses infrared technology to detect movement up to 25 feet away, so it turns itself on whenever you walk into the room and turns itself off after you leave. Its light sensitivity dial enables it to only go on when the room is dark.

My main problem with it was the price – almost $20. But, if the manufacturer is right, one motionbulb can last as long as 10 incandescence lightbulbs and it saves energy. $20 for at least 5 years of usage doesn’t sound bad at all.

How much under $29.99?
Some: $19.95 on motionbulb.com.
