The Firefly PRO rescue strobe lights are among the brightest and most feature-rich strobe lights on the market today. With three activation functions, you can switch between the ultra-bright strobe or the SOS strobe to visually alert search and rescue services to your location, and then switch to the steady-on function for close-range rescue operations. Choose between the Firefly PRO SOLAS (non-water activated) or Firefly PRO Waterbug (water activated) versions. Attachment to a life vest is possible.
The brand-new Firefly PRO Waterbug is a SOLAS-approved strobe light with a built-in water activation feature that automatically activates as soon as it is submerged. The LED produces a 360° light beam that is over 41 candela bright and offers visibility of over 3 miles. With the completely new microprocessor and energy-efficient electronics, the Firefly PRO operates continuously for over 56 hours.
