My left hand beam is 7 x xpg-r5 and other diver white beam is solarstorm dx4. More yellow spot beam is old hid of diver 3.
6000 lumen 4 xml-u2 is weaker than 3000 lumen 7 xpg-r5.
Solarstorm is still OK and enough for diving. 18650 batteries can’t drive full power so 26650 is needed.

Actual power from battery is 2,4A x 7,13V = 17w x 0,90 -> 15w led power -> 1500 lumen.
Hello ! I am considering one of these solarstorm diving lamps. Have you had any problem with it ? What do you think of it in comparison to other diving lamps ?
