GENERAL ELECTRIC NATIONAL MAZDA Economical Electric Lamp HYLO 40W 115V
Lampe économique à double filament de tungstène
Wolfram-Glühlampe mit zwei verschiedene Lichtstärken

Ca. 1917.

The HYLO (turn down) lamp has two filaments, one short and one long, that can be switched on and off with a string that is integrated into the base, which moves a switch inside. You could use the large filament for regular lighting, and you could use the smaller filament as a night light for example, all at the flick of a switch. These lamps were also advertised for their power-saving benefits.

The HYLO (carbon) lamps were initially manufactured by THE PHELPS COMPANY in Detroit, Mich. U.S.A. The first brevet was filed by William J. Phelps in 1905.
