Just got my lightdims in the mail the other day and they work great. I got the silver ones, should have gotten the original ones too though as the sliver ones stick out on a couple of things like my cable box and st50. And you can go through them really fast if you have a lot of electronics, some leds are very bright and will take multiple to block them out so they are just faint, even though the sliver ones are supposed to be 80-90%. A couple on a surge protector that really bugged me at night took over 5 layers, i did not keep count. the st50 light took 3 to block it out but some still leaks out through the crystal trim. That happens with a lot of things too, but any light leakage is no where near as bad as a naked led. black electric tape would be a lot quicker to block it out completely but for things that you still want an indication that they are still working properly, like a surge protector, lightdims are great. Plus i tested to make sure they leave no residue and they don't, so that's good. And thanks to Randy for mentioning it, i had never heard of them, helping me get some better sleep .
