What is the luminosity of the MK-79?

Explanation:
Brightness is rated in candlepower for signaling flares, indicating how strong the light output will appear from a standard viewpoint. The MK-79 is a compact hand-held illumination flare used on ships to light decks or mark a position. It is specified to produce about 12,000 candlepower, giving a bright, short-lived light that is bright enough to reveal objects on a dark deck or at signaling range without excessive glare. Values lower than this would be too dim for practical use, while much higher values belong to larger or longer-duration signaling devices. So, 12,000 candlepower is the standard luminous intensity for the MK-79.
