What candlepower is specified for the MK-79 red star display?

Explanation:
The important idea here is the brightness of a distress signal, measured in candlepower. The MK-79 red star display is specified to have a luminous intensity of 12,000 candlepower. That level of brightness is chosen so the flare can be seen from several miles away at night, helping rescuers locate you. The other numbers would imply lights that are far too dim to be reliably seen at sea (or, in some cases, far brighter than what’s typical or safe for signaling). So 12,000 candlepower best matches the standard specification for this flare.
