Very bright as I expected.
I have bought 3 of these lights. One of the lights leaked during my second dive at 12 meters depth. Apparently it leaked either through the power switch buttons or the front lens. The battery compartment was fine and I was able to save my batteries. I tried to explain it to the store and requested a refund. They asked for a video showing the light was not working. To my surprise, the light turned on after it dried, but I showed that there were rust and salt deposits inside the front compartment. They only offered me a $4 dollar discount... I conclusion, I think quality control of these lights seems very poor and you might get a light that won't even last 5-10 dives.
