Apex Pro 275 Lumen Princeton Tec Headlamp. When you need the power, versatility, and ruggedness of our Apex headlamp, but your adventures require a lighter weight, you need the Apex Pro. Over 100 grams lighter than our original Apex, the lighter and faster Apex Pro was designed with the unique and ever evolving needs of professional athletes and extreme adventurers in mind. The Apex Pro is powered by 2 CR123 lithium batteries protected in a highly durable and waterproof casing.
With it's waterproof LED headlamp design, the Apex combines a single regulated Maxbright LED partnered with four regulated Ultrabright LEDs. The Apex provides either a powerful spot beam capable of pumping out 275 lumens of pure light on high power. or a bright flood of light. Switching between the two is incredibly easy with its large waterproof push button switch even with gloves on. Proprietary heat sink technology allows the LEDs to burn brighter and longer.
