Good product. Works wellI need a rough use light bulb for my garage door opener and I couldn't find any in the local stores so I was very glad to find these. I ordered enough to hopefully last me for a good long time.I tried a few different types of bulbs in my opener. They just can't handle the shaking that opening puts on them. This bulb will last a good year if it's anything like my last set.Bulb lasted about 6 weeks when should easily be more than 2 years. Contacted seller would not do anything about it. DO NOT buy these online. In my opinion I feel these are inferior/rejects that are being sold by third parties.They say they have a 1,000 hour life, but I am skeptical. These bulbs just don't seem to last very long.Bought two of these ruff service for my garage. Both have failed within a month of installing. Different locations in the garage both have failed after less than month . I remember when GE meant quality, no longer. Would not recommend these bulbs.I wanted GE Light Bulbs because GE is the best. This ad says that these lights are GE and they are SATCO which is a brand I've never even heard of! This really is outrageous! FALSE ADVERTISING!Should not have started this review..not being a pain. Very happy with the product I received but when I tried to buy more It denied me. Don't remember why.
