The Firefly PRO Waterbug offers four activation functions: an armed mode for automatic water activation, an ultra-bright strobe mode, an SOS strobe mode to visually signal Search and Rescue of your location, and a Steady-On mode for close-up recovery operations. Its cool white LED light has no yellow tinting, giving a more visible beam that can be seen at greater distances than a warm-toned light.\u003c\/p\u003e\u003cp\u003eWide light emission LEDs produce a 360 degree beam of light at 41 candela, giving a visibility range of over 3.5 miles. An energy efficient microprocessor and redesigned electronics maximize operation life in harsh conditions. Running on a single set of AA alkaline batteries, the Firefly PRO Waterbug strobes continuously for over 56 hours, or runs the Steady-On feature for 28 hours, exceeding USCG and SOLAS minimum requirements. The compact 4.4 x 2.2 x 1.2 inch housing fits easily inside an inflatable life jacket or a pocket for comfortable wearability, and the military spec casing is built to withstand years of abuse in harsh marine environments. Two lashing loops plus an included Velcro strap make it easy to mount the strobe to a life jacket, belt, or pack so it is readily accessible when needed. The unit is factory tested waterproof to 33 feet (10 m) and is backed by a 1 year manufacturer warranty.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e ACR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 3971-3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActivation Modes:\u003c\/strong\u003e Armed (water activation), Strobe, SOS Strobe, Steady-On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWaterproof Rating:\u003c\/strong\u003e Factory tested to 33 feet (10 m)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLamp Type:\u003c\/strong\u003e Cool White LED\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStrobe Intensity:\u003c\/strong\u003e 41 candela\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStrobe Visibility:\u003c\/strong\u003e Over 3.5 miles\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStrobe Flash Rate:\u003c\/strong\u003e 60 flashes per minute +\/-\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStrobe Operation Time:\u003c\/strong\u003e 56 hours minimum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSteady-On Operation Time:\u003c\/strong\u003e 28 hours\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertification:\u003c\/strong\u003e SOLAS, USCG, MED, TSO-C85b, IMO LSA, CE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Source:\u003c\/strong\u003e AA alkaline batteries (not included)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 4.4 inches x 2.2 inches x 1.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Yellow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Two lashing loops with included Velcro strap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1 year manufacturer warranty\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the ACR Firefly PRO Waterbug Emergency Strobe Light?\u003c\/strong\u003e It is a SOLAS-approved emergency strobe light, ACR part number 3971-3, that features a built-in water activation function so it automatically turns on once submerged.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Firefly PRO Waterbug turn on by itself in water?\u003c\/strong\u003e Yes, when set to Armed mode the ACR 3971-3 automatically activates its strobe once it is submerged in water.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow long will the strobe run on a set of batteries?\u003c\/strong\u003e The Firefly PRO Waterbug strobes continuously for 56 hours minimum on a single set of AA alkaline batteries, or 28 hours when running the Steady-On feature.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat batteries does the ACR 3971-3 use?\u003c\/strong\u003e A single set of AA alkaline batteries powers the Firefly PRO Waterbug;
