THE EFFECTS OF LIGHT ON LUMINOUS BACTERIA.
A conservative statement would therefore be that luminous bacteria show no changes in luminescence as a result of illumination by 625 foot candles for 1.5 minutes when examined 1/200 of a second after exposure, and none as the result of illumination by 15,000 foot candles for 6 minutes when examined (1/6) of a second after exposure.
