The maximum brightness of one of the prothoracic light organs of the West Indian elaterid beetles, Pyrophorus (measured at Princeton, New Jersey) was found to be .045 lambert, or .045 lumen per sq. cm. at 20°C. This corresponds to .0002 candle for one organ, or .0004 candle for the pair of prothoracic organs.
