You may or may not be screwed over by the manufacturer. LED's, are inherently much more efficient than CFL and incandescent bulbs. However, as they are a new and emerging lighting technology, there will be problems. Just as was the case with early CFL bulbs, cheap, off brand Chinese manufacturers started to sell products that promised rewards, and never delivered. GE, on the other hand, has built a quality and reasonably priced low power LED bulb, using modern drivers, and high power LED's. Needless to say, the LED's that are found on Christmas tree lights use low power LED's (the 3,5,8, and 10mm varieties.) and don't seem to drive them properly. LED's will, in fact last 50K hours, but not if they are overdriven to produce more light. Overall, LED bulbs will eventually come down in price, and go up in reliability, just as CFL's did years ago.

As I said in the article, I planned to do a very positive article on the pluses of LEDs (I think they are great). But, in doing my research, I found that there may be some issues as well. I thought it was my duty to present these issues so that readers could make a fair judgement. As with any emerging technology, there are bugs to work out. I didn't mean for the article to scare people away from LEDs, just go in with their eyes open. To jrc: I understand how you feel.

They were amazingly inexpensive ($4 for a string of 100 colored lights made in China) but I searched in vain for any information on power consumption. Let's make SURE that next Christmas any products like this have that information for consumers!

It's just like regular lights, but more efficient, and safer. Everything wears out, everything has mistakes made on it. This article is fear mongering. I think YOU are over hyping the downsides.

I also use LED's for my interior lighting. Some I have had over 20 years and they still work fine. Unlike incandescent lights, I can hold mine while it is on against my skin and I dont get burned (Christmas trees?) I use the flat type now, like is used on the space station. I have 2 right now, one is like those and the other is the miniature 'bulb' like shown in the second image above (the red LED). The flat type puts out more lite, and uses under 1 watt (0.97) of power to light 25 of these (as one fixture). The other also has 25 tiny lights (like the red one in your picture but white) but uses 2.7 watts of power. The ones I have had 20 years that I still use are red. I was not able to easily find "white" LED's until around 6 years ago. I have no incandescent nor florescent lighting, it is all LED's that are DC (direct current) and you can "burn them out" by giving them more than their rated power input. I dont know about the currently available decoration type lights. I live in semi-remote Alaska and dont have access to stores very often (nor need to). (and off topic, but when I do go, its normally on horseback I have not driven my car in several months) But they also make LED headlights. The power to run electronics in your car comes from your alternator, so the greater your electric demand for headlights etc, the more your alternator needs to work, which requires more gasoline if that's your cars power source. I recommend LED's But also as you note, pay attention to the quality of any product you purchase. I have been using solar and wind for 35+ years.
