This was a great replacement for my C7 bulb. The biggest difference between these and other LED replacement bulbs is the filament used and that they are made of plastic rather than glass. They are very similar to regular incandescent bulbs, the only real difference is that they are brighter and a bit whiter, and of course because their LEDs use about 10% of the energy. I dropped one while installing and because it's plastic it didn't break and still worked great. They were installed at PNW within a few weeks and some of them now have water in their pistons. Also, during installation, part of the plastic housing came off the lamp base (3 out of 100) and 2 didn't work right away. I think these are great lamps and probably work best indoors. Since I've used them, 2 more have failed, so out of the 100 I've bought, 7 haven't worked one way or another. For my application (Christmas lights) I would not buy them again or recommend them. For internal use they will probably be fine.
