I bought them 2 years ago. 2 bulbs went into garage door opener and still work. The third bulb got caught in a closed lamp in the stairwell and stopped working after less than 2 years. Maybe defective? In any case, I'm now wondering if it's worth the extra money for "enclosed fixtures" rated incandescent bulbs. They also give off a super white light which is fine for utility purposes but I would have preferred a warmer light. UPDATE August 2021: This company stands behind their product and warranty. I informed them that the bulb had failed earlier and within a week I had a spare on hand. I'm still not sure if that bulb from the kit was faulty but they got it right and fast.
