Use it, drain it, recharge it. Rechargeable flashlights are convenient, effective, economical and a great option for anyone who uses their flashlight a lot. But if you are planning on using your flashlight only sporadically or sticking it in the glove compartment, car boot or disaster preparedness kit, a rechargeable flashlight is NOT the right choice. Unlike disposable lithium batteries, rechargeable batteries self-discharge over time. If you stow a rechargeable flashlight, the battery may not have any juice left by the time you actually need it.
If 'Action' will be your flashlights second name (Surefire being its first), an Advanced Rechargeable torch is for you. Every Surefire rechargeable kit (excluding the 10x Dominator) include two Ni-Cad batteries. So while you are using one battery, the other can be charging in its rapid smartcharger cradle, which automatically monitors the charging process, ensuring a perfectly charged battery in less than 2 hours, kits also include a 240-volt AC power supply transformer and a DC accessory plug to charge your lights battery via the cigarette lighter socket of a car or boat. So you can keep the whole use-drain-recharge cycle going when you are on the move.
What goes into a Surefire Xenon Torch
Although they may be old school technology, incandescant lamps are capable of generating high output beams that, when teamed with the right reflector and bezel, can reach far into the night. And of all the incandescant torches on the market, Surefire xenon incandescants are by far the best.
An incandescant lamp works by running electric current through a tungsten filament until it heats up enough to emit light. Off-the-shelf, run-of-the-mill filaments wont do for Surefire, they use custom designed, custom wound filaments in their lamps, In addition, to maximize the lamps output and operating life, while minimizing tungsten boil off (a process that can form a layer of light blocking tungsten on the inside wall of the bulb, Surefire bulbs are filled with expensive high pressure xenon gas and, in some models, a halogen addative.
Surefire's high performance xenon lamps are precision placed within perfectly shaped aluminium reflectors coated with light smoothing micro-texture. The result is a beam with no obvious hot spots, dark rings or imperfections. A protective window made from tempered Pyrex glass coated with a layer of anti-reflective materieal to minimize light loss covers the reflector and bulb assembly. Wrap it all up in a tough, aerospace grade aluminium or polymer body. Seal the body with O-rings. Power it with compact lithium batteries that carry a 10 year shelf life. Now you've got a world class illumination tool that performs at the highest level in virtually any conditions.
