LED light bulb

When I was at Fry's Electronics the other day, I found these neat LED lightbulbs. They are a bit expensive but they're energy efficient. They are made by Normande Lighting and plug into standard 120VAC light bulb socket. For $7.99 you could get a 30 lumen light bulb that expends 700 milli-watts and should run 30,000 hours, or 3.5 years. So at 10 cents a kilo-watt hour this thing should cost $60/year if you ran the thing continuously. If you ran a 70 watt light bulb like that, you'd be looking at $6,000/year. And I don't think standard light bulbs last 30,000 hours. So I put this as a porch light. It keeps the Money Pit illuminated with a soft eerie glow. Celle calls it moonlight. The street is a bit dark, so this also keeps the Money Pit from looking completely scary at night.

There are more powerful ones that get up to the 7 watt and beyond, but that'll run you upwards of $25 a bulb. So they're not cheap.
