Experience enhanced visibility and endurance with Tektite's Strobe 3500, a robust polymer upgrade from the well-loved Strobe 3500 XL Expedition. Not only does it offer a significantly brighter output, but it also guarantees a superior battery life compared to the Strobe 300. The Strobe 3500 features a powerful 10-watt LED strobe that shines intensely enough to be spotted for miles at night (under the right conditions with a clear lens). Made from ABS and Lexan, this strobe is meticulously designed to withstand harsh conditions, surpassing the durability of the Strobe 300 by eliminating any fragile glass strobe tubes. Furthermore, the Strobe 3500 comes with double O-ring seals, ensuring it's waterproof and depth-rated to 500' (150 meters). Powering this stellar strobe are 3 C-cell alkaline batteries, providing an impressive burn time of 100 hours. The strobe boasts a rapid flash rate of 120 flashes per minute (2 Hz) when equipped with fresh batteries, and features a twist-on rotary switch for easy operation. What's more, the LED strobe offers a fantastic life expectancy of 10,000+ hours (equating to 36+ million flashes). Measuring 9.25" x 1.9" (23 x 5 cm) and weighing only 12 oz. (340.2 g), the Strobe 3500 provides substantial light without the bulk. Available in multiple colors, it comes with a hook and loop strap for easy attachment. This high-quality strobe light is proudly crafted in the USA.
