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