The Firefly Pro SOLAS emergency distress light is capable of producing 41 candela of light per strobe for up to 56 hours on AA lithium batteries. With its wide light emission LEDs, the Firefly Pro cuts through foul conditions by creating a super-bright flash which be seen for over 3.5 miles. Three activation functions allow users to toggle between ultra-bright strobe or S.O.S. strobe to alert search and rescue, then toggle the steady-on feature for close-up recover operations.
