Compact and versatile, the blue CF450 Adjustable-Beam Dive Light from Bigblue gives you the choice of a narrow spot beam or a wide flood. This 5.2" anodized aluminum light comes with a diving glove so you can keep it on your wrist while holding your tray or adjusting your camera's controls, and is controlled by a magnetic tailcap push-button switch. Twist the bezel to adjust the beam from a tightly focused 7° spot to a wide 37° flood beam. Runtime is two hours on a fresh set of three AAA batteries, included.
