Can't say much as I haven't installed them yet, but since these are Cree Leds I'd expect them to be quite BRITE indeed. I had to research these all over the net to find the LU(min) output which is 1150. Wish this was stated in YOUR description??
update! These are some really nice lamps, and by far brighter then the 1150 lumen suggest. Now will just have to see how long they last, but they are well made so expect them to be around for years.
