The Tovatec Fusion 530 is a great all-around dive light with its adjustable 12° to 100° degree beam angle and 530 lumen output on full power. This midsized light is small enough to fit in your BCD pocket as a backup or powerful enough to be used as a primary light and versatile enough to be used as a video light. With the adjustable beam angle you can add an adapter to your camera tray arm and turn your light into a 100° degree video light. Accepts either 3 x AAA alkaline batteries (not included) or lithium-ion rechargeable battery. Includes lanyard, CR18650 lithium-ion battery, charger, & USB cable. The Fusion 530 provides a maximum lumens output of 530. The light uses a lifetime CREE XM-LT6 LED lamp, and the light head slides to adjust beam angle from 12° to 100° degrees making it perfect for narrow beam tech diving to wide angle lighting for photography. The Tovatec Fusion 530 has a color temperature of 5600°K - 6800°K. All Fusion lights have a removable head for cleaning or expanding your beam angle to 140° degrees. With the head removed, it can also be used as an emergency candle strobe or deck light. Simply grip the vent holes on the lens then unscrew the top portion of the lens above your hand. The light is still waterproof without the focus lens attached. Built to last from rugged aircraft grade aluminum housing that reduces weight and provides years of service and a rubberized grip for extra durability and long life.
