We've had Santa's Sleigh and 4 Reindeer on our roof during Christmas Season for over 25 Years. And after 2-3 seasons of use the lights are just done in. The restringing is horribly time consuming, but they have been a staple in our neighborhood so we do it. We decided to restring last year with LED's as they were touted to last many thousands of hours and save electricity. Bull----. One reindeer failed one string in 3 weeks. We said, ok we must have gotten a bad set, mounted the roof, pulled the deer down and partially restrung it. By the end of the season all but part of one reindeer were out. The sockets/bulbs rusted, the LED 'caps' laying on the roof or just missing with a rusted cavity left behind. Did anyone at UL Labs that tested these products and labled them ok really test them for the use they were intended? Did anyone consider using copper wire(or some other non rusting metal) in the construction of the LED? Not only the lost time, more than double the cost, and utter disapointment,( the kid's faces used to glow as much as the reindeer did. We feel we were ripped off. The only way we saved electricity was because they weren't lit at all. We strongly advise anyone that is considering these lights for outdoor purposes to do your homework. No, we didn't contact Phillips. We're not the confrontational type, but I did tell the owner of the local hardware store, and everyone who asks.
