The best in breed L4 dominates all other flashlights in its class. This small but powerful illumination tool unleashes 100 lumens of perfectly focused light - more than enough to temporarily overwhelm an attackers night-adapted vision. And the tough L4 can take a hit. With no filament or glass to break, its LED virtually indestructible, and its insides protected by a weatherproof, hard anodized aluminium body.
While the L4's beam is undeniably bright, it's also incredibly smooth and effective. A bright central beam surrounded by a gradually diminishing corona makes it perfect for illuminating what lies ahead, while enhancing peripheral vision.
Compact, powerful, tough and it can run for hours. Count on the L4 LumaMax to do its duty no matter what its up against.
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.
