Antwoord op "Half of the string of LED Christmas lights doesn't light up."After reading most of the Q & A's here. I don't know why anyone in their right mind would bother to buy these lights! It seems to me that the manufacturers are getting away with daylight robbery. I recently bought three sets of NOMA Leds and after succesfully testing them ok, spent nearly four hours installing arounf the roof of my house. They worked fine the first time I switched them on but the second night half of one set was out and the next night half of another set failed to light. What a rip-off!
