This Bigblue FF-1x5W AFO LED Focus Dive Light (Black) is a compact but powerful LED focus light featuring the Auto Flash-Off function. Today's modern digital cameras have very accurate auto focus features but they require a certain amount of light and contrast in order to function. Sometimes this is a problem underwater, so having a continuous light mounted above the port will help the camera to focus. The FF-1x5W AFO is perfect for this purpose since the Auto Flash-Off function will automatically turn off the light for 3 seconds when your strobes fire. This way the focus light will not affect your photo even if you are shooting at a slow shutter speed. The 1 5W LED provides 200 lumens of light that should be bright enough to assist your camera's auto focus even on night dives.
The FF-1x5W AFO is powered with 4 AA batteries; both Alkaline or NiMH will work. It has a burn time of up to 8 hours. The light is constructed from aluminum alloy, and is anodized, to be anti-corrosive. The FF-1x5W AFO can also be used as a back-up light for cave diving or as a primary for some diving situations. The light has a color temperature of 6500 °K, and a beam angle from 60°. The light has a unique "Flying-Fish" shape, and features a rotary magnetic switch with transportation lock.

Comments about Bigblue FF-1x5W AFO LED Focus Dive Light (Black):
I purchased this after looking at other reviews. I shoot underwater with an Ikelite housing and a DS5q Substrobe, and wanted a focus light that I could use on night dives without having to figure out how I was going to attach it or carry it. This solved the problem, as the ball fixture attaches to the opposite side of my housing with a simple Ikelite clamp. Nice light, and the auto-off works like a charm.Nice that it comes with an attachable handle in case I couldn't take my camera - at least I'd have a decent night light! Lightweight, although kind of an odd shape. The only negative I found was that the ball attachement chipped paint immediately (Not the light itsself, only the ball) Would definitely recommend this.
