The parade of the headlamps continues. Princeton Tec has taken their 3-Watt LED Apex and placed it on a diet. The Apex Pro weighs 106 grams (3.7 ounces) less than its AA powered cousin, the Apex. The weight reduction was achieved by changing the battery pack. The Apex Pro uses 2 CR123 Lithium batteries.

The reduction in weight does come at the cost of a shorter overall burn time though the regulated burn time period is actually slightly longer in 3 Watt High mode.
The Apex Pro is powered by 2 CR123 Lithium batteries. The lamp contains a single 3-Watt LED and 4 ultrabright 5mm LEDs and supports 2 modes in both Low and High operation. Overall burn time for the 3-Watt mode 36 hours; 48 hours in the 5mm LED mode. The lamp weighs 6.1 ounces with batteries.
