I think they're cool, but that's as far as it goes.
We just installed 8, double bulb, 4' fluorescent lights for a customer. She got these bulbs that I had never seen. Instead of fluorescent, they each had like 280 tiny LED bulbs in a straight line pointing down. She said they're supposed to last for 80 years, and they cost $85.00 apiece. 85x16= $1360.00. That's a lot of money for bulbs. Pretty bright though.
I don't believe for a second that they will last 80 years, either. Maybe in theory, but not in real life.
