This Bigblue FF-3x5W AFO LED Focus Dive Light (Sapphire) 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 light level and contrast range 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-3x5W AFO is perfect for this purpose since the Auto Flash-Off function will automatically turn off the light for 2 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 3 5W LEDs provide 500 lumens of light that should be bright enough to assist your camera's auto focus even on night dives, inside caves, or wrecks.
The FF-3x5W AFO is powered with 8 AA batteries, both Alkaline or NiMH will work. It has a burn time of up to 12 hours. The light has a Hi-Lo power output switch that lets you choose between, Hi at 100%, or Lo at 70%, extending the burn time and reducing reflections on objects at close range. The light is constructed from aluminum alloy, and is anodized, to be anti-corrosive. The FF-3x5W AFO can also be used as a primary light for some diving situations. The light has a color temperature of 6500K, and a beam angle from 60°. The light has a unique "Flying-Fish" shape, and features a rotary magnetic switch with transportation lock.
The Auto Flash-Off function automatically turns the light off for 1 second when your underwater strobes are triggered, avoiding that accidental spot light from ruining your photos, even when shooting at a slow shutter speed
