The SDL-600 is an incredible new kind of underwater dive light which has no batteries, and therefore never needs charging. Developed by SWES Technology, the SDL-600 dive light is natively designed to operate in seawater, as it will not turn on when it is dry.
Instead of storing energy in the form of battery that constantly needs to be recharged, the SDL-600 instead uses a series of SWES EnergyCells which are catalyzed with exposure to seawater. You read that right, SWES has developed and released the first ever underwater dive light that is powered by a fuel cell.
The SDL-600 is currently only designed to work in seawater, not freshwater, and operates best when it is submerged in clean, warm salty ocean water. This light uses a single Cree XM-L2 LED capable of producing 600 lumens of light in a 50 degree beam angle, with a bright spot up to 1100 lumens in its focus point.
The SDL-600 dive light costs $500, is capable of going down to 100 meters deep, and can run for 2190 hours, or about two years with three hours of daily use. Of course if you use it less and keep it clean you can extend the lifetime of the light.
We don’t have to tell you that a light that can ‘never’ run out of power during a dive is the best insurance policy you could have while diving in a dark environment. SWES has an unassuming corner booth here at DEMA but if you want to see a bit of magic, definitely swing by and check out the SDL-600, a dive light which will never go out when you need it the most.
