The Fusion 530 Video LED Dive Light from Tovatec is an all-purpose dive light that can be used on any recreational dive or on an all day expedition. The light produces a maximum of a 530 lumens, and a runtime of 3 hours is possible on one 18650 Li-ion battery (included) or 2 hours and 30 minutes on three AAA alkaline batteries (availble separately). The magnetic slide switch on the body of the flashlight selects three power settings of 30%, 50%, and 100% and an emergency strobe mode. The Fusion 530 is made of an aircraft-grade aluminum alloy and has a rubberized grip. The Fusion 530 Light Adapter (available separately) allows the light to attach to any tray arm. When not in use, the midsized LED flashlight is small enough to fit in your pocket. The head slides to adjust beam angle from 12 to 100°, which gives a narrow beam for technical diving and a wide angle beam, good for photography or video. When the head is removed, it will expand to a 140° angle beam, which can also be used as an emergency candle strobe or deck light. The pressure safety valve located on the bottom, is there to protect the housing and the operator in case of a battery malfunction.
