Tensor High Intensity Lamp (ca 1959, Brass, steel, copper, plastic, glass). Kept at Brooklyn Museum. Gift of Jay Monroe

Tensor lamp is a small high-intensity and low-voltage desk lamp invented by Jay Monroe.[1][2] The lamp was mainly popular during the 1960s and 1970s.[3][4] The lamp was originally used by doctors and dentists, and later became more widely used.[5]

History

The first Tensor lamp consisted of assembling together a 12-volt automobile parking light bulb and reflector made from an ordinary kitchen measuring cup. Monroe fixed the cup to a metal tube that was attached to a transformer, which reduced 115-volt house current to 12 volts. Because of the small bulb, the entire lamp could be made smaller with a light-directing shade.[6]
