Sealion L24 video light

A wide, flat 120 degree flood at 6500 K and CRI 90, which is what a video light needs: an even wash across the frame rather than a hot spot in the middle. 12,000 lumens is more than a reef at 15 m (50 ft) ever asks for, and the headroom is the point, because full power lasts about 70 minutes and half power lights a coral head just as well for far longer. The two extra colors earn their place. Blue at 455 nm makes corals fluoresce, and with a yellow filter over the lens a reef you dived in the afternoon glows green and orange at night. Red is for watching rather than filming: many night animals barely react to it, so a hunting octopus keeps hunting. The battery pack comes out, so a spare means no waiting between dives.
