Used by scuba divers, military, and fire fighters worldwide. The civilian version of our covert ops military strobe, our STROBE 200™ LED strobe features improved flash rate, lamp life, and durability compared to the previous Xenon version as well as competing Xenon strobes. This double O-ring sealed, waterproof unit will run 30+ hours on a set of fresh batteries (included), is dive rated to 500 feet (150 m), and can be seen for miles at night (conditions permitting with a clear lens). Since it uses a high-intensity LED strobe module there are no fragile glass tubes to break. Includes, at no additional cost, a Velcro strap. Optional colored lenses are available. An Infrared (IR) version is available to approved government and military organizations. Safer and less expensive to use than standard strike flares.
