Rated 5 out of 5 by 1 reviewer.
Rated 5 out of 5 by Good value when purchased in bulk. These are fine standard bulbs. I was surprised to find that I could buy a pack of 12 for the same price as about four individual bulbs, so of course I got 12. I suggest getting together with friends, or maybe you can sell them on Craig's List. Whatever. December 17, 2014
