I am not sure if a high intensity LED works well under water, especially with 6500K tint. Water molecules cause a big backscatter effect with a large proportion of blue light. 538m range - under water or on land? Personally, I doubt that the light will reach that far, even i.a.w. ANSI/FL1. Have you really tested and measured the maximum range in (sea) water?

Moreover, I do not know if divers would benefit from a thrower flashlight with a 5° narrow beam. Most activities (beyond signaling someone) happen in close proximity, so a flood light with high color rendition (CRI) might be the better option? 2hrs runtime at Turbo seems unrealistic unless you are referring to ANSI, i.e. start the flashlight on turbo and let it run until the output has dropped to a certain (very low) degree.

I like the design. The side switch actually looks like a knob that can be turned to cycle modes. Will 21700 batteries fit, too?

I agree with having a high CRI, yet I found throwers far more useful than any flood.
The narrowest of beams quickly widen underwater.
If the water is slightly turbid, with flood you end up with a wall of blindness in front of you, and your fellow divers.
Throwers with blinking modes let you signal to fellow divers as you noted, often used to point out life of interest (sometimes sound signals fail) flood for photography, not much else.
Narrow beams let you see if there is anywhere to explore.
Most importantly, throwers give a hint of anything to be cautious and avoid.
The best 26650 might give an hour at 1600 (need review of this), it would be nice if the “smart temperature control” doesn’t throttle down the lumens and make it like every other dive light.

it would be interesting to hear what actual divers have to say, what tint is actually better under water, and if hi cri leds actually have any benefits under water,

a diver on fonarevka .ru tried several different lights under water and said the best results were using green light, it gives sharper picture compared to any white tint.

Thanks for your liking the design! Smile It’s a dive light, used for various diving occasions. And the max beam throw is 538m underwater. It can be powered 1×18650/26650 batteries, not fit 21700. And this light is designed for narrow spot beam, to get more throw distance and features a focused light. When making technical diving for exploring caves, wrecks, you will need a spot dive light. If you are interested in flood lights with high color rendition (CRI) , can also check xtar D30 1600, D30 4000
