LED Christmas lights! Hooray! I can decorate the house with lights for less energy and for much cheaper than before.
They're made by Phillips. They're on sale right now at Target for about $10 for a 20ft strand of 60 lights. Yes, they're more expensive than the regular energy guzzling kind, but I'll feel better about lighting up the house every night.
Now if they'd just come out with an affordable fiber optic-lit Christmas tree that was larger, had sturdy branches for ornaments and was not so gaudy looking, I could replace my 20 year old 4ft artificial tree.
