The WL-S4 is equipped with the MT-G2 LED from CREE, which can output a scorching 2600 lumens, while in Turbo mode. There are a total of seven outputs modes, with two of them being Strobe and SOS. Accessing these modes is done via the side switch, while the tail switch is used for on and off. Cycle through the 2600 lumen Turbo mode, 1050 lumen High mode, 360 lumen Mid mode, 100 lumen Low mode, finally down to the 5 lumen Moonlight mode. While in Turbo mode, a maximum beam distance of 380 meters can be achieved, which is equivalent to just over four football fields. Also, the new circuit design provides double the intelligent protection for the LED and battery, maximizing their lifespan and ensures safety.
Powering the WL-S4 are four CR123A batteries or you can go rechargeable route and use either four RCR123A/16340 batteries or two 18650 cells. Depending on which batteries you choose, you can maintain outputs and run times, giving you some extra versatility. The WL-S4 is impact resistant to 1.5 meters and waterproof in accordance with IPX-8 standards, so you don't have to worry about the batteries or LED getting damaged when raining or if submerged in water.
