I've been using LED Christmas lights for three years now. They claim to be 80% more efficient than incandescent bulbs. They also now have "soft-white" lights that closely resemble the color of white incandescent lights. The fist year I used them it said you could string three sets of them together, now they say you can string 46 sets together. I think the first-year set is improperly marked.
