EOS Tactical Headlamp - Olive DrabThe EOS Tactical headlamp is compact, military tough and is housed in an ultra light, 3 AAA platform.Princeton Tec’s premiere overmolding process results in a waterproof, drop-proof, reliable housing. This headlamp boasts four output modes, the strongest of which can shine up to 48m.The EOS Tactical headlamp comes with three interchangeable color filters: red, green and blue.Core Technology: FOCUSED NARROW BEAM - This pattern creates a long, powerful beam of light excellent for illuminating distant areas, or for use during fast paced activities.IPX7 - Lights provide waterproof integrity down to 1 meter for up to 30 minutes.LED OPTIC COLLIMATOR - A collimator gathers all available light from an LED in the form of scattered rays and re-emits the light as parallel rays, making it more optically efficient than a standard reflector. Princeton Tec calibrates each collimator to the type of LED and application of each light. With proprietary optimized collimator/lens systems, Princeton Tec continues to advance LED technology.MAXBRIGHT LED - The highest quality LED available. Princeton Tec’s Maxbright LED is extremely bright and efficient. This single LED emits a smooth, powerful, white light useful for a wide range of tasks. Princeton Tec uses collimators or reflectors with the Maxbright LED depending upon the application. Must yell "MAXBRIGHT" when saying term out loud.MULTIPLE MODE - Multiple settings on many of our products give you the flexibility to adjust your light’s brightness to illuminate greater distances or to conserve battery power, depending on your needs.REGULATED LED - Lights that feature regulated LEDs have a sophisticated regulating circuit that maintains initial brightness as long as the batteries have sufficient voltage. They are so sophisticated that if they had eyes, they would definitely wear a monocle. Traditional lights are very bright initially, but immediately begin to dim and continue to dim until the batteries are drained. Constant Brightness is a term used to describe products that have regulated LEDs.Specifications:Power: 60 LumensLamp: 1 Maxbright LED (regulated)Burn Time: 108 hoursBatteries: 3 AAA Alkaline or LithiumWeight: 3.6oz/103gWater Resistant: IPX7Warranty: Lifetime
