A friend of mine took this video and posted it on vimeo (link below). His video lights are close to 10,000 lumens. The wreck is an old ferry named Bellubra about 2km off Sydney beaches and in about 160ft. The RAM worked great although I have it positioned up a bit too high. I have a Y block fitted to the hookah port for an inflator and octy. Rgds. Phil
