Had Nanight Tech 2 for about 150 dives and it was really good light. Would say it's pretty hard to flood because it has external charging port and you never have to open it unless you want to change the lens. You can have 120deg, 35deg and 10deg spot with different lenses. Sold it because I wanted a bigger battery for heating, not because there were anything wrong with the light.
Nanight is not 4000lm all the time, you can find the graph from manual and see how lumens drop with time.
