Float-On Light The ACR Float-On is a buoyant water activated strobe and LED flashlight.  The strobe automatically activates in the water when its integrated water sensors detect 6 seconds of water connection.  The separated and sunken water connection terminals ensure the device only automatically activates when fully submerged in water.  The high-power LED strobe, visible up to 3 nautical miles away, flashes once every second for up to 20 hours and acts as an exceptional safety aid for both novice and experienced boaters. The ACR Float-On is a must-have addition to your safety toolkit.  It provides a simple and cost-effective safety solution for family, friends, and even pets.Features:LED Flashlight Water activated strobe lightBuoyantLED Battery Life IndicatorUSB RechargeableTechnical Specifications:Dimensions (H x D) - 3.26" x 1.3" (8.3 x 3.3 cm)Weight - 1.5 oz (.04 kg)Light Output - High - 120 lumens, Medium - 60 lumens and Low - 10 lumens Runtime (hours) - High - 1.5, Medium - 4, Low - 12, Strobe 20 and Standby 1,440Charge Time - 1.5 hoursBattery - RechargeableBuoyant - YesWaterproof - IP67 In the Box:Float-On lightLanyard with clipUSB Charging cableInstruction Manual*Sold as an Individual WARNING: This product can expose you to chemicals including di(2-ethylhexyl)phthalate (dehp) which is known to the State of California to cause cancer, birth defects or other reproductive harm.
