What Princeton Tec Says About the EOS Headlamp
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. 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.
ULTRABRIGHT LED. The Ultrabright LED is bright and efficient. The smooth, white, wide-beam light emitted by Ultrabright LEDs is ideal for close to mid-range tasks. Ultrabright LEDs are usually grouped together to offer a more powerful light source. Advances currently underway will continue to improve the efficiency and brightness of Ultrabright LEDs. "Ultrabright" can also be yelled when using the term in conversation, but not nearly as loud as "Maxbright".
