Bought a 4 pack 3 months ago. 1 has failed completely and another is starting to flicker. As a retired semiconductor process engineer, I thought this was going to be a great investment. Obviously that is not the case.
Installed in an outdoor post light (bulb enclosed) on Monday. Bulb was flashing on and off on Thursday evening. Bulb had moisture inside envelop. Better sealing is needed. Please hire a better engineer.
One lasted only two days. A second one lasted about three weeks. I really like the light they give off and the expected savings on the electric bill but I am thinking I made a mistake buying so many. I won't buy any more.
Bought 6 of those about two years ago.
Of those, two have failed outright. On the other 4, the glass cover has become completely loose.
They buzz when they are dimmed, and I tried several different dimmers.
Bought 4 one failed after a month. Remaining 3 still working and on a dimmer with no issues c. 2mos.
Note Cree reads its reviews. They're shipping me a new one so I don't have a problem with customer service.
