Our first batch of S12s accidentally included one of our 4Sevens lanyards, though the S12 has no lanyard attachment. Future batches won't have the lanyard, but feel free to keep it if you get one :)

The S12 is the new benchmark for ultra compact, insanely bright tactical and duty flashlights. It is the smallest flashlight in the world to use the SST-90 emitter.

It features both current and 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.

The S12 also runs off one of our own special lithium-ion rechargeable batteries. It's called a 26650, and it packs enough energy to power the S12 at 800 lumens for an entire 90 minutes.

The Maelstrom S12 features a simple, two-mode interface that takes only a few seconds to master. To start, please make sure the S12 battery is inserted with the positive side (+) toward the head. Then, tighten the tailcap fully down and the S12 will turn on. Loosen the tailcap a half-turn, and the S12 will turn off.

The S12 tailcap has a pressure-style switch. When the tailcap is loosened a half-turn, simply press the button on the back to activate the light. The switching mechanism is momentary, which means when you stop pressing on the button, the S12 will turn off. To 'lock' the S12 on, simply tighten the tailcap fully down again.

To switch between the high and low output modes, turn the S12 off, and then turn it on again within 1 second. Anytime the S12 is turned on within 1 seconds of being turned off, it will automatically switch to the next mode. However, if you leave the S12 off for 2 seconds or longer, it will "memorize" the last mode used. See the examples below:

Example 1: ON (High mode) --- OFF (1 Second) --- ON (Low Mode)
Example 2: ON (High mode) --- OFF (2 Seconds) --- ON (High mode)
