The Maelstrom X10 is a tactical duty light that features CREE's latest XM-L emitter for blinding output, two-stage output modes for simple versatility, and thermal regulation for guaranteed dependability.

The X10 is both current-regulated and thermally regulated - 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 X10 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 X10 at 640 lumens for an entire 1.8 hours.

The Maelstrom X10 features a simple, two-mode interface that takes only a few seconds to master. To start, please make sure the X10 battery is inserted with the positive side (+) toward the head. Then, tighten the tailcap fully down and the X10 will turn on. Loosen the tailcap a half-turn, and the X10 will turn off.

The X10 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 X10 will turn off. To 'lock' the X10 on, simply tighten the tailcap fully down again.

To switch between the high and low output modes, turn the X10 off, and then turn it on again within 1 second. Anytime the X10 is turned on within 1 seconds of being turned off, it will automatically switch to the next mode. However, if you leave the X10 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)
