This is junk. Ordered August 2016, I have used four of these to replace a bulb in a fixture of 12. All but one of the original bulbs are still on, 1.5 years old. Once installed, these bulbs are significantly brighter and the longest lifespan is around four weeks. The last one I replaced last week died tonight. I never touched the glass and used styrofoam to remove the bulb and insert it into the socket, so I think they were made for lower voltage use than 120v. They are burned black. I ask Revain to return the money.
