I purchased 3 pro's last year. One of the strips had 5 lights go out in about 11 months, ecoxotic replaced it no questions asked, so the customer service was great! They used to be 19 watts and now they are 16 watts, that may help prolong the life of them? My other two original strips are working fine though. If you are putting them in a canopy I'd recommend having a small fan blow across them to help keep them cool
