Discussion on “standard marine electrical installations” (Hornor), San Francisco, Cal., Sept. 16, 1915. (see proceedings for August, 1915)

S. H. Blake: Historically this paper does not go back to the time when the standard navy voltages were based on the use of searchlights at 80 volts. This was somewhere in the period up to 1904, at which time the navy voltage standard was increased to 110–125 volts in order that standard commercial lamps could be used. Since then 240 volts and higher are also employed.
