Here at Northern Led we use EPISTAR LED Chips which are of high reliability and quality With an extremely low failure rate. When we say our products last, it's true, we use top quality components. Be careful choosing cheap LED strip, their is a lot out there with poor quality LED Chips in circuit with lower valued resistors. The problem with low valued resistors is that when the strip is powered up, they allow that strip to drive a high current which results in the strip burning out over time. LED Strip lasts, if you have the right components. Thanks.
