As HID and high-power LED lights are becoming cheaper and more common, I was wondering if there were any concerns about their effect on the behaviour patterns of the fishes and other creatures encountered during night dives.
For example, I suspect a group of divers wielding Light Cannons etc. (not to mention photo/video strobes) probably turns night into day for the 30 min - 1 h they explore a section of a reef. Are there "safe" lights out there that do not unduly stress the animals while ensuring the divers know where they are and where they are going?
