LED Lenser M7R Rechargeable SLT Flashlight 880010 combines environmental friendless, value-based efficiency, and high powered lighting into one durable, versatile flashlight from LED Lenser. Like many of their professional grade flashlights, LED Lenser has equipped the M7R with Advanced Smart Light Technology (SLT), which enables the user to cycle between three distinct programs, each with their own set of lighting functions, for a total of 8 different beam types to choose from. With Advanced SLT, you're always only a few clicks away from the Power, Boost, Low Power, Dim, Blink, S.O.S., and Defense Strobe modes, each with their own benefits. Even more control over the flashlight is granted via the Rapid Focus system, which allows you to switch from a focused spot beam to a wider, more diffuse area light simply by pushing the bezel forward with one finger. The LED Lenser M7R Rechargeable Flash Light has a modular construction which allows for fewer points of contact, reducing the chances for your flashlight to malfunction. You'll get years of cheap, efficient use out of this LED Lenser flashlight, if only because you won't have to buy batteries very often; the flashlight is powered by a single ICR18650 rechargeable battery, which is juiced up using the Floating Charge System. All you have to do to power up your LED Lenser flashlight is plug the magnetic charger into the wall, touch your flashlight's end cap to the magnet, and let it be; your flashlight will stay in place, charging, without bulky cords, plugs, or adapters, until you're ready to remove and use it once again. When you first unleash the 210 lumens of the LED Lenser M7R Rapid Focus Lamp, you'll be amazed at the power LED Lenser has managed to eke out of a single rechargeable battery, and you'll probably never go back to a standard flashlight.
