This is the big brother to the LED 10 W sidemount primary light. This light is an optimal combination of quality, size and performance. The 10.4 Ah canister is light and compact, but still, with the LED 10 W light head it manages to power the head for more than 10 hours straight. It recharges completely in roughly 3 hours. Spot beam in cool white with soft corona provide the light you need when diving that wreck, that cave or that reef at night time.
