Update: Seller states 3 year warranty for similar BR40 27000K lamps. I contacted them about this and they also have a 3 year guarantee and they replaced 2 bulbs with no problems. Upgraded 1 star for excellent service. Maybe lightbulbs last longer in less cold regions than in Alaska. 4 were used outdoors. With very limited use, 2 stopped working. They were used in outdoor motion detectors and turned on an average of no more than 1/2 hour a day for about 12-18 months. Biolus claims 23 years of life at 3 hours a day. Not even close. It is worth noting that they generally do not give any guarantees on their lamps. The lamps are also relatively heavy. Make a good bright light while they last.
