Antwoord op "Half of the string of LED Christmas lights doesn't light up."my particular LED's operate on AC (noticeable strobe/flicker in peripheral vision much like an old CRT tv) I looked at the strand and actually pulled an LED out, and there is in fact, no diode. There is also no in-line box or anything indicative of additional in-line electronics. They also pass 120V AC to the next strand (and in my case, through 10 strands) because they power small incandescent mini light globes at the end. A friend of mine just put up all his led strands and low and behold there are at least 3 or 4 sets out of 15 that are completely dead. They worked last year and were stored indoors, not abused or damaged.
Antwoord op "Half of the string of LED Christmas lights doesn't light up."hmm..same problem. These LED's contain NO fuses and the bulbs are not removable. Half a strand out, flip the plug 180 degrees and the other half is out. This set is in the middle of about 10 sets, and the lights before, and after work fine. screwy..
