The Fusion 1000 provides an amazing amount of light for any dive whether you are diving on a wreck, in a cave or just drifting along a reef. Put the light in video mode by simply attaching your light to one of Tovatec's camera tray arms, then sliding your lens to 100° degree beam angle. Accepts either 3 x AA alkaline batteries (not included) or lithium-ion rechargeable battery. Includes lanyard, rechargeable CR26650 lithium-ion battery, charger, & USB cable. The Fusion 1000 provides a maximum lumens output of 1000. The light uses a lifetime CREE XM-L2U2 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 1000 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.

The light is still waterproof without the focus lens attached.
