I've bought several 12v bulbs over the years and they're always good, but I always end up collecting a few because we need more brightness (lumens) that I don't can measure these but I have ones that are 900 lumens and if these aren't 500 lumens they should be pretty close, super bright and changing the environment they are in, everything comes alive when you turn them on. No noise during operation (another important thing for us, there are some designs that make a buzzing noise that we can't deal with). If you're on the fence give them a try, really helpful!
