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 LED Torch
There is a lot of buzz about light emitting diodes (LEDs) and for a good reason. LEDs allow runtimes that were previously unattainable on a single set of batteries. When it comes to longevity, they are in a class by themselves, the thousands-of-hours class. That is because they are a solid state device, no filament to burn out or break, no gas or liquid components, no glass to break. Just a semiconductor chip that converts electrical energy into light, which it disperses through a tough, clear polymer covering.
LED output levels are approaching, even surpassing in some cases, those of incandescents. But for raw lighting power, Surefire’s three, four and six battery incandescents are still the way to go. However, and incandescent lamp becomes particularly useless if the power level drops below the amount of energy required to make its filament glow white hot. An LED, on the other hand, continues to function at power levels below its maximum output level. Which means an LED will continue to run – albeit at lower and lower output levels. So you get more useful light for a longer period of time with an LED flashlight than with an incandescent.
Not all LEDs are created equal. They can vary greatly in quality, even supposedly identical LEDs made at the same facility. Surefire uses only the finest, highest quality LEDs in its illumination tools. They are electronically controlled for maximum efficiency, focused by a reflector or Total Internal Reflection lens for a perfect beam, and housed in a rugged, weatherproof, knurled aerospace grade aluminium body that keeps the elements out and your flashlight in hand.
