The company, in its earliest form as Federal Electric, a lighted sign company, was founded in 1901. It later made home and kitchen appliances, neon signs, police sirens, and circuit-breakers. Everything but circuit-breakers had been spun off or sold off to other companies by the 1940s, and the name was changed to Federal Pacific Electric.
Neon sign. The neon sign is an evolution of the earlier Geissler tube, [11] which is a sealed glass tube containing a "rarefied" gas (the gas pressure in the tube is well below atmospheric pressure). When a voltage is applied to electrodes inserted through the glass, an electrical glow discharge results.
Neon tubes may partially burn out, and a conservator may identify the burned out portion of a neon artwork through use of a neon light tester, also known as a test light or voltage tester. This electronic test device is used to determine whether an electric current is running through the equipment being tested.
At all phases of the neon evolution, neon signs have been hand-blown and bent over fire by skilled tradespeople. The result is a one-of-a-kind, handmade piece with a shelf life of up to 100 years.
