The Apex is the pinnacle of waterproof LED headlamp design, boasting up to 200 lumens of output. With its 4 light levels, safety flash mode, and impact-resistant design, the Apex is an ideal headlamp for any hardcore adventure. The Apex combines a regulated Maxbright LED with 4 regulated Ultrabright LEDs, for constant brightness on all modes. Switching modes has never been easier – the dual switch system allows you to independently control the intense, smooth, long-range lighting from the Maxbright LED, and the wide-angle, close-range lighting from the 4 Ultrabright LEDs. Proprietary heatsink technology allows the LEDs to burn brighter and longer. The Apex is compatible with alkaline,lithium, and rechargeable batteries.
