I have replaced almost all of my light bulbs with led light bulbs from this company. They have stood firm to their warranty policy of 3 years. I put one of their bulbs on a dimmer and it burned up in 1 hour. I emailed them about it and was told that the bulb I put on the dimmer was not dimmable. They let me keep the bad one without returning it and shipped me a new one that was dimmable for FREE. I only paid $10 for the bulb.
