The Princeton Tec Yukon Extreme headlamp incorporates a sophisticated circuit to control power and maximize the performance of the LED's and incandescent filaments. The circuit maintains constant brightness and automatically compensates for different battery chemistries. This feature allows the user to install alkaline, lithium, NiCad or NiMH batteries.

The Yukon Extreme headlamp also incorporates soft start technology to protect the bulb filament from excessive current surges upon turn-on.

The Princeton Tec Yukon Extreme incorporates a single switch to turn the light on and off and to select the light source. From the off position, a full press of the switch(until it clicks) turns on the LED's in high power mode. A momentary partial press of the button switches to the high incandescent filament. The next momentary partial press switches to the low incandescent filament. The fourth momentary partial press switches to the LED's in dim mode. A fifth partial press begin the sequence again. A full press of the switch at any time will turn the light off.

The Yukon Extreme's textured reflector provides for a broad beam of light but allowing sufficient throw to illuminate objects at a distance. The LED's are great for up close work and times when extended battery life if important. The 8AA batteries are housed in a nylon pouch with an integral belt clip and hang clip. The LEDs will light for over 24 hours at constant output and allow for days of light with diminishing brightness. The advanced design of the Princeton Tec Yukon Extreme headlamp allows for the Xenon lamp to operate with nearly constant light output for over 2 hours on a set of alkaline batteries.
