Greetings, my name is Michael, and I have been documenting and photographing Detroit's streetlights for years, however it is only recently that I have acquired 2 old GE arc lamps from the city, which were later

This armature g is a piece of iron in the shape of a hollow cylinder, having on each side a segment cut away, the width of which is equal to 6 5 the width of the pole-pieces m n. The armature is soldered or otherwise fastened to the clamp 0', which is formed of a brass … This is a General Electric “Intensified” arc lamp dating from about 1912 or so. It is designed for interior use, and lamps like this could be found in large spaces like department stores and large building lobbies. Arc lamps were widely used for street lighting from the late 1870's well into the 1900's, but they were also used for interior illumination in larger spaces.

The lamp is a spark or electric arc through the air between two carbon rods. The rods must have a gap in between of the right size. If the gap is too big than the arc will flicker more or may go out, if the gap is to narrow than it will produce less light. The first carbon was made of charcoal (made from wood).

Over the next   What type of arc lamp? Most have a ballast and will not “see” the line voltage across its terminals. Assuming it does, then V = I R R = V / I R = 220 / 20 I = 11 Ohm. Image: Selected Tesla Patents: Electric Arc Lamp Displaying image 4 of 200 images in Physics.

‘Arc lamp’ or ‘arc light’ is the general term for a class of lamps that produce light by an electric arc. The concept of carbon-arc lighting was first demonstrated by Sir Humphry Davy in the early nineteenth century using charcoal sticks and a 2000 cell battery to create an arc across a 4-in. (100 mm) gap.
