These are the brightest LEDs are I've ever seen. Most of the specified number of lumens is indeed greatly exaggerated, but here you can believe it. Now I can tell if I get dark blue or black socks out of the closet in the morning last. Even warm white can believe. 4 of them are now three months use, light up every day about 1 hour and so far neither flickering nor any complaint. Bright and light, but some people have to get used to the brightness maybe, I wanted that.
Well, now have three abandoned by 4 LEDs to mind first began flickering, then it was all over with the beautiful brightness. From this product (Green Line), I can only strongly advise against.
