The Apex Extreme is taking cold weather explorers, cyclists, climbers, and backpackers to new heights. The Apex Extreme provides the same ability and power as the original Apex, but stores its batteries in a remote compartment that can be clipped close to your body for optimal battery warmth and usage in cold temperatures. In addition, the external battery pack reduces the weight on your head. Having the longest burn time of the Professional Series, the Apex Extreme is perfect for winter months when the nights are longer and the temperatures are dropping.
No returns will be accepted on this item unless it is a warranty issue.
4 ULTRABRIGHT LEDS
The highest quality LED available, 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 effi ciency and brightness of Ultrabright LEDs.
8 AA Alkaline
BATTERY POWER METER
The battery power meter provides you with continuous feedback on the condition of the batteries, indicating high, medium or low battery life. This information allows you to make educated decisions about changing batteries or packing spare batteries.
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.
This beam pattern combines focused narrow and focused wide beams to allow for the most versatility. At close range, the focused wide beams simulate normal daylight conditions so you can take advantage of your peripheral vision. The focused narrow beams create a long-throw spotlight ideal for night hiking and search and rescue.
Multiple settings on many of our products give you the flexibility to adjust your light’s brightness and/or beam width to illuminate greater distances or to conserve battery power, depending on your needs.
REGULATED LED / CONSTANT BRIGHTNESS
Princeton Tec lights that feature regulated LEDs have a sophisticated regulating circuit that maintains initial brightness as long as the batteries have sufficient voltage. 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.
WATERPROOF - LEVEL 1
Level 1 is assigned to lights that offer a degree of water protection equivalent to IPX4 in the International Electrotechnical Commission (IEC) standards. Lights rated at Level 1 are designed for water resistance to splashing and quick dunkings. If a light with a Level 1 rating is accidentally submerged for a longer period of time, the batteries should be removed and the cabinets should be carefully inspected for signs of battery leakage. If water has entered the housing, the light should be dried and batteries replaced.
WEIGHT - 416
Princeton Tec’s advertised product weights always include batteries. For many products, battery weight is a large percentage of overall weight. Weight can be significantly reduced by using lithium batteries in lithium-compatible products.
The light output of Princeton Tec lights is measured in lumens. A lumen is unit derived by the International System of Units (SI) for measuring light output.
