The link you quoted does not make it possible to determine the true output of the light. It would appear to have substantial output however as it is claiming only one hour of output on it's highest intensity. With 4 18650 cells; probably they are supplying 2600 mAH cells which would give you around one amp of power to each LED. Depending on which bin they are pulling from the light should either be really bright or god awful bright. You should not need the filter if you are close to the subject. The wide-angle lens will not allow even this much light to penetrate very far in the water and you would then need the wins the subject is further away. Let us know how you like the lights as this seems like a good deal on a powerful light if they work well and have an even beam spread.The light is 120dollar each , i buy 2 and shipping cost 16dollar , total 256dollar .. its brand Nemo , these company base in USA and Hong Kong , they make tools for underwater like drills and grinder , i do google for information about their product and believe they still new in the market for dive light , u can see here
