In Seahorse RORC Club page pyrotechnics were discussed….

The brightness of white flares varies significantly the best giving off 10K candela and the worst 2.5K. The only way to find out the candela is to check the manufactuere’s data sheet as it is not on the flare container.

During the Holligan V incident a wave dropped into the flare container which promptly sand along with the rest of the flares. A suggestion is to store them in a buoyant container. Also it was noted that flares have different ignition systems which are hard to read in the dark when in the water. The storage of flares needs to be accessible so that in the case of a capsize they are very easy to find.
