Bought 10 of these bulbs in August 2016 from Revain. 8 out of 10 failed, also the pins were loose and stuck in their holder. Also, some of them actually split in half. While they lasted, they had good light output. But my old lightbulbs will last for years. Maybe I got a bad batch and maybe CB Concepts will contact me to fix the problem. I'll report back when they do.
