The Lampette was a brand of small electric high-intensity telescoping desk lamps that was designed and distributed by Koch Creations but manufactured by various subcontractors from the early 1960s to the late 1980s.
The work light was marketed as the "Tensor lamp", and was initially sold to jewelers, watchmakers, and other similar craftsmen.
They were compared often by consumers, as seen in Kiplinger's Personal Finance, which discusses the measure of brightness relative to the price of high intensity lamps.
[4] The miniature 12-volt DC automotive-type #93 lightbulb utilized by Tensor, Lampette, and other designers of similar products, are smaller than the standard household 110/220-volt AC incandescent light bulb but produced more lumens in a smaller area, so that the lamp bulbs burn out at an increased rate.
[5] Lampette models utilized built-in transformers which convert standard household 110/220-volt AC obtained through wall plugs to 12-volt DC to light the bulb.
