UPDATE: May 11 - just received the replacement light, it appears to be new in box. Less than 2 weeks from when I first contacted them. So now I am very impressed with the lights and with their customer service. UPDATE: Got an email from customer service, sounds promising so I added a couple of stars, will update again if things go well. When I installed 2 of these lights in September I was very impressed. Now at the beginning of May on one of the lights more than half of the LEDs have stopped working. If you look there is not reference to a warranty. I went to the sellers website and still not warranty information. I have sent a message to the seller, but have not heard back. If I get a response I will update this review.
