Previously, we have been offering 1 year warranties, which are industry standard, but at Reef Breeders, we pride ourselves in providing excellent customer service, and like to go above and beyond the industry standard. This warranty will also encompass all previously purchased fixtures that were sold in the last 2 years, and covers any and all flaws in manufacturing, or shut-downs due to blown fuses, etc. (not including user damage, like water spillage). We will pay for shipping both ways, and repair or replace the fixture free of charge, or help you do so. Enjoy your new LED fixtures!
