LED Christmas lights tend to be a bit more pricey than the incandescent ones, but they may pay for themselves over time. They use less energy to operate, so that's always a good thing. They also create less heat, so less danger of fire. Always good too. I really need to buy some new Christmas lights anyway, so I figured I'd go for the LED ones this time around. Have you made the switch? I even read that you may be able to get a discount on new LED lights at some stores if you bring your old incandescent ones in and trade them in. Cool.
