These lights are great! At first I didn't want to spend that much on a lightbulb until I took my lightbulb from storage only to find the filament was broken! Never used and it was broken. Not only do these LED lights come with a 10 year guarantee. but they don't have brittle threads that break easily, and the outer shell is made of plastic that doesn't break either. Now what about the lighting? GREAT! They are so bright that I am still in shock when I go to the bathroom. I couldn't be happier. And they use less energy than my old lightbulbs. Very satisfied.
