Bought 14 (7 pack) of these bulbs to replace the crappy old fluorescent bulbs that were buzzing. The light distribution was excellent. Turns on instantly and silently, and looks a lot more modern than the old devices they replaced. My only issue is that 2 out of 14 lightbulbs didn't work. I'm returning a box and buying a replacement. I hope this works as I want to love these bulbs but so far the 15% failure rate of these devices is worrying.
