Description
The Maelstrom S18 is a veritable hand-held spotlight that features 4Sevens' unique thermal regulation and a blistering high output of 1200 OTF lumens. The S18 is unlike any flashlight out there, utilizing innovative design technology to provide the versatility and dependability you've come to trust in a 4Sevens flashlight.
Current Regulation: Current regulation means that the S18 intelligently controls the power being drawn from your batteries, giving you consistent output while fully using every last drop of energy available. Current regulation provides dependable outputs and runtimes while eliminating needless battery waste.
Thermal Regulation: The S18 features our unique thermal regulation. This means it can take serious abuse and be exposed to harsh conditions, but it will automatically control its output to protect its own guts. That means you don't worry about your light - you just use it.
SST-90 LED: We only use the absolute latest cutting-edge LED technology in our flashlights, and the Maelstrom S18 is no exception. It features the "SST-90" LED, a luminous giant of efficiency and output, providing 1200 OTF lumens on high mode.
Smart Circuit for Rechargeable Batteries: Many flashlights are able to use standard single-use 3-volt CR123A batteries, but few can use the more powerful, rechargeable 3.7-volt RCR123A batteries without causing permanent internal damage. The Maelstrom S18 is one of those few - it runs flawlessly even when using six rechargeable 3.7-volt RCR123A batteries.
Reverse-Polarity Protection: The S18's battery carrier provides reverse-polarity protection, so even if you accidentally put the batteries in reverse, nothing will be damaged. So even if you're swapping batteries in the dark, you've peace of mind that you simply can't hurt the S18.

Operation
Operating the Maelstrom S18 flashlight is intuitively simple. First ensure that all six batteries are installed correctly in the battery handle. To access the battery handle, unscrew the tailcap in front of the red o-ring, where the five mode icons are engraved. The battery handle is permanently attached to the tailcap, so please remove it carefully.
Once you have installed the batteries and tightened the tailcap, press the metal button on the back until it clicks and the light will turn on. You can also press the button lightly for momentary-on. To change modes, simply rotate the back of the tailcap to align the engraved arrow with the icon of the mode you want.
