My rope lights only last a year...The product description says....."The lights themselves are extremely long-lasting--they're rated at 35,000 hours". My lights are on a timer for 8 hours a day for 365 days or + - 3,000 hours of use, these didn't even come close. I am going to try to get a free replacement but my guess is I'll get turned down or it will cost more to ship the lights back then what they originally cost....
