Not as bright as stated, but much better light than others.
I ordered two flashlights; one a UV Blacklight and the other a 3800LM flashlight. I thought that the 3800LM was supposed to be the brightness of the flashlight. I have a friend who has a 1000 Lumen flashlight and the one I received was not as bright; however' the quality of the spread of light was excellent and much cleaner than that of my friend's. I really hate flashlights that are bright in the center and has inconsistent lighting from the center out to the edges. It makes it hard to actually see what you are trying to illuminate. The one I received might be 800 lumens, but it is consistent and clean from center to outer edges. I'll take this flashlight before I would even consider my friend's. I just wish they would put the correct brightness in the description. It does provide a wide full light that makes it easy to see everything in view. It does zoom in and out. When fully zoomed in, you do see the shape of the LED. This is typical of the Cree XM LED. The UV light is good. Don't go to your friend's house and use it in the dark on their toilet. You'll never use it again... You might check yours...
