History

The ''Hygrade Sylvania Corporation'' was formed when '' NILCO'', ''Sylvania'' and '' Hygrade Lamp Company'' merged into one company in 1931. In 1939, Hygrade Sylvania started preliminary research on fluorescent technology, and later that year, demonstrated the first linear, or tubular,

, and later a 10-flash unit called FlipFlash, as well as a line of household electric light bulbs, which continued during GTE's ownership and today is sold by Osram Sylvania. In June 1964, Sylvania unveiled a color TV picture tube in which europium-bearing phosphor was used for a much brighter, truer red than was possible before. Through merger and acquisitions, the company became a significant, but never dominating supplier of electrical distribution equipment, including transformers and switchgear, residential and commercial load centers and breakers, pushbuttons, indicator lights, and other hard-wired devices. All were manufactured and distributed under the brand name GTE Sylvania, with the name Challenger used for its light commercial and residential product lines. GTE Sylvania contributed to the technological advancement of electrical distribution products in the late 1970s with several interesting product features. At the time, they were the leading supplier of vacuum cast coil transformers, manufactured in their Hampton, Virginia plant. Their transformers featured aluminum primary winding and were cast using relatively inexpensive molds, allowing them to produce cast coil transformers in a variety of KVA capacities, primary and secondary voltages and physical coil sizes, including low profile coils for mining and other specialty applications. They also developed the first medium voltage 3 phase panel that could survive a dead short across two phases. Their patented design used bus bar encapsulated in a thin coating of epoxy and then bolted together across all three phases, using special non-conductive fittings. By 1981 GTE had made the decision to exit the electrical distribution equipment market and began selling off its product lines and manufacturing facilities. The Challenger line, mostly manufactured at the time in

, was sold to a former officer of GTE, who used the Challenger name as the name of his new company. Challenger flourished, and was eventually sold to Westinghouse, and later Eaton Corporation. By the mid-1980s, the GTE Sylvania electrical equipment product line and name was no more. In 1993 GTE exited the lighting business to concentrate on its core telecomms operations.

Osram Sylvania

Osram Sylvania manufactures and markets a wide range of lighting products for homes, business, and vehicles and holds a leading share of the North American lighting market In fiscal year 2008, the company achieved sales of about 1.75 billion euros, which comprised about 38% of Osram's total sales at the time. Osram's worldwide lighting businesses employed about 9,000 people at the time. In 2016, Osram spun off the general lighting business which included the North American Osram Sylvania unit into an independent company called LEDVANCE headquartered in Garching, Germany. In 2017, LEDVANCE was merged into a consortium of Chinese investment companies and the Chinese lighting manufacturer MLS under the LEDVANCE name.

''. The grand prizes on the show would be Sylvania television sets, and some consolation prizes would be Sylvania radios. Sylvania "Blue Dot (tm) for sure shot" flashbulbs would be used to take a photograph of the contestants in awkward outfits or messy stunts. * One of Sylvania's heavily advertised TV features was a lighted perimeter mask of adjustable brightness called "HALOLIGHT", which was purported to ease the optical transition if a viewer glanced from a dark background to the bright TV screen. Today Philips markets an Ambilight feature, lighting the wall behind a flat display to soften the viewing experience. HALOLIGHT could not be adapted for color TV, because color TV white balance (aka tracking from low to high brightness) was unpredictable. Since the white color temperature of the HALOLIGHT and the illuminated color screen could not be made equivalent, HALOLIGHT was withdrawn. * Osram Sylvania sponsored the
