The Firefly PRO Solas emergency strobe light boasts an all new light output power management system that produces over 41 candelas of light per strobe for up to 56 hr of use (with AA lithium batteries). Using wide light emission LED’s, it cuts through even the toughest conditions, creating a super bright flash visible for over 3 miles. When it comes to saving lives, anything less than the best is not an option. The all new Firefly PRO rescue strobe lights are the brightest and most feature packed strobe lights on the market today. With three activation functions, toggle between the ultra bright strobe or the SOS strobe to visually alert search and rescue of your location, then toggle to the steady on feature for close up recovery operations. Our innovative new wide light emission LED’s produce a 360 deg beam of light (41 cd) allowing for visibility of over 3 mile. Our cool white light has no yellow tinting which allows for a more visible light beam that can be seen at greater distances. With an energy efficient microprocessor and redesigned electronics, the Firefly PRO boasts maximum operation life in the harshest of conditions. With a single set of AA Lithium batteries, the Firefly PRO will continuously strobe for over 56 hr or use the steady on feature for 28 hrs. That is twice as long as our competitors and exceeds USCG and SOLAS requirements by over 48 hrs. The new compact size will easily fit inside an inflatable life jacket or pocket for comfortable wear ability. The military spec casing is rugged enough to withstand years of abuse and the harshest environments. The two lashing loops and included Velcro strap make mounting the Firefly PRO to your life jacket, belt or pack extremely easy so that the strobe light can be readily accessible the moment you need it.
