Originally posted by gaweidert Racer, a few years ago I went with really expensive LED lights for outside. Most of the strings did not last the season. One bulb out and 1/3 of the strings shut off. Seems that water can work it's way into various nooks and crannies and when you only have 5 or 12V in the lines it shuts them down. Played with them for a few years to keep them working. Threw out the last string this fall when most of it would not come on. I have also been using some of the small incandescent for years. Some of them cost me all of $1.98 for a hundred light string after Christmas was over. They just keep on trucking along. Too bad too as the LED lights were great when they worked.
The LED strings that lasted less than a season were about $30 for a string of 150. So for me it is LED inside and incandescent outside. The energy consumption for the strings of small incandescent lights is about the same the energy usage for the LED strings of similar length and bulb count. Both use very little electricity.
We have been using an artificial tree for several years now. New main tree this year with 750 built in LED lights. Came with a remote and you have the choice of warm white or colors. Plus several different pattern schemes. Works pretty good and at 52 pounds it is heavy enough that the cat cannot pull it down.
These were on sale at$16.90 ea, I got 16 strings and 2 power cords (connect up to 10 strings per power cord). Commercial grade, and outdoor rated, the heat shrink at each bulb has mastic in it, sealing every connection from moisture intrusion.

When the order arrived I connected 8 strings each onto a power cord, plugged them in and left them on for a day. Inside of the first few minutes half of one string flickered and then went out. I contacted the merchant, and a replacement arrived a couple days later, no questions asked.
If an electronic device is going to fail it will most likely do so when new. Statistically the infancy mortality rate of these types of things is much higher than that of old age.
The lights are rated for 50,000 hours of seasonal use, so once they get past their infancy, they should last a very long time.
And as long as I am careful not to damage the wires (they are quite robust, compared to the incandescent strings) they should provide many years of trouble free service.
