Use LED holiday lights
LED lighting is improving all the time, but it’s not yet advanced enough to be able to replace CFLs as a standard for low-energy lighting around the home. One place you can definitely use LED lights is for decorating your house and/or Christmas tree this holiday. This year we’re selling LED holiday lights in our green store.
**How this helps**
The bulbs can last up to 50,000 hours (that’s over five years of continuous lighting — no more tweaking every bulb trying to find the dud!) and use up to 90% less energy than standard incandescent bulbs. One estimate puts the potential savings at over $8 for just one tree’s worth of lights!
