Thomas Research Products is a lighting manufacturer that is wholly owned by Hubbell Lighting Inc. [1] Based in Elgin, Illinois, the company designs, manufacturers and supplies energy-saving electronic lighting components and integrated light engine modules for luminaires. [2]
Thomas Research Products was founded in 1997 as a manufacturer of quartz restrike controls which sense when a high intensity discharge light is extinguished, and automatically light a standby secondary light source [3] in commercial and industrial lighting. [4]
Over time, the company expanded its product line to include additional electronic controls for both HID [5] and fluorescent lighting. [6] The company also added LED power supplies, known as drivers, and accessories. [7]
In 2012, the company began to develop LED light engines, beginning with the introduction of a complete module that provided an energy efficiency rating exceeding 100 lumens per watt. [8] The following year, the company entered the AC LED market with light engine modules that do not require LED drivers. In 2014, the company moved to a larger facility in Elgin, IL with larger manufacturing, warehouse, engineering and office space.
Koninklijke Philips N.V., commonly shortened to Philips, is a Dutch multinational conglomerate corporation that was founded in Eindhoven in 1891. Since 1997, its world headquarters have been situated in Amsterdam, though the Benelux headquarters is still in Eindhoven. Philips was once one of the largest consumer electronics companies in the world, but later focused on health technology, having divested its other divisions.

High-intensity discharge lamps are a type of electrical gas-discharge lamp which produces light by means of an electric arc between tungsten electrodes housed inside a translucent or transparent fused quartz or fused alumina arc tube. This tube is filled with noble gas and often also contains suitable metal or metal salts. The noble gas enables the arc's initial strike. Once the arc is started, it heats and evaporates the metallic admixture. Its presence in the arc plasma greatly increases the intensity of visible light produced by the arc for a given power input, as the metals have many emission spectral lines in the visible part of the spectrum. High-intensity discharge lamps are a type of arc lamp.
A mercury-vapor lamp is a gas-discharge lamp that uses an electric arc through vaporized mercury to produce light. The arc discharge is generally confined to a small fused quartz arc tube mounted within a larger soda lime or borosilicate glass bulb. The outer bulb may be clear or coated with a phosphor; in either case, the outer bulb provides thermal insulation, protection from the ultraviolet radiation the light produces, and a convenient mounting for the fused quartz arc tube.
A compact fluorescent lamp (CFL), also called compact fluorescent light, energy-saving light and compact fluorescent tube, is a fluorescent lamp designed to replace an incandescent light bulb; some types fit into light fixtures designed for incandescent bulbs. The lamps use a tube that is curved or folded to fit into the space of an incandescent bulb, and a compact electronic ballast in the base of the lamp.
A metal-halide lamp is an electrical lamp that produces light by an electric arc through a gaseous mixture of vaporized mercury and metal halides. It is a type of high-intensity discharge (HID) gas discharge lamp. Developed in the 1960s, they are similar to mercury vapor lamps, but contain additional metal halide compounds in the quartz arc tube, which improve the efficiency and color rendition of the light. The most common metal halide compound used is sodium iodide. Once the arc tube reaches its running temperature, the sodium dissociates from the iodine, adding orange and reds to the lamp's spectrum from the sodium D line as the metal ionizes. As a result, metal-halide lamps have high luminous efficacy of around 75–100 lumens per watt, which is about twice that of mercury vapor lights and 3 to 5 times that of incandescent lights and produce an intense white light. Lamp life is 6,000 to 15,000 hours. As one of the most efficient sources of high CRI white light, metal halides as of 2005 were the fastest growing segment of the lighting industry. They are used for wide area overhead lighting of commercial, industrial, and public places, such as parking lots, sports arenas, factories, and retail stores, as well as residential security lighting, automotive headlamps and indoor cannabis grow operations.
The induction lamp, electrodeless lamp, or electrodeless induction lamp is a gas-discharge lamp in which an electric or magnetic field transfers the power required to generate light from outside the lamp envelope to the gas inside. This is in contrast to a typical gas discharge lamp that uses internal electrodes connected to the power supply by conductors that pass through the lamp envelope. Eliminating the internal electrodes provides two advantages:
A light fixture, light fitting, or luminaire is an electrical lighting device containing one or more light sources, such as lamps, and all the accessory components required for its operation to provide illumination to the environment. All light fixtures have a fixture body and one or more lamps. The lamps may be in sockets for easy replacement—or, in the case of some LED fixtures, hard-wired in place.
Acuity Brands, Inc. is a lighting and building management firm headquartered in Atlanta, Georgia, with operations throughout North America and in Europe and Asia. As of 2018 the company has approximately 13,000 employees and recorded net sales of $3.7 billion for the fiscal year. In terms of market share, Acuity Brands is the largest lighting manufacturer in North America.
An LED lamp or LED light is an electric light that produces light using light-emitting diodes (LEDs). LED lamps are significantly more energy-efficient than equivalent incandescent lamps and fluorescent lamps. The most efficient commercially available LED lamps have efficiencies exceeding 200 lumens per watt (lm/W) and convert more than half the input power into light. Commercial LED lamps have a lifespan several times longer than both incandescent and fluorescent lamps.
Plasma lamps are a type of electrodeless gas-discharge lamp energized by radio frequency (RF) power. They are distinct from the novelty plasma lamps that were popular in the 1980s.
The L-Prize competition was designed to spur development of LED light replacements for 60W incandescent lamps and PAR38 halogen lamps as well as an ultra-efficient "21st Century Lamp". It was established by the United States Department of Energy (DOE) as directed by the Energy Independence and Security Act of 2007. The original competition, launched in 2008, focused on an LED replacement for the common 60-watt light bulb and this L-Prize was awarded in 2011. The PAR38 competition was launched but received no entries and was suspended in 2014. The 21st Century Lamp competition was never opened.
Sylvania Lighting, Havells-Sylvania, and SLI, is an international designer and manufacturer of lighting products, trading as Sylvania. It has plants throughout Europe, Asia, North Africa and Central and South America, and is one of the few lighting companies that produces both lamps and lighting fixtures. It is owned by Shanghai Feilo Acoustics Ltd., having previously been owned by the Indian electrical company Havells.
United States Lighting Energy Policy is moving towards increased efficiency in order to lower greenhouse gas emissions and energy use. Lighting efficiency improvements in the United States can be seen through different standards and acts. The Energy Independence and Security Act of 2007 laid out changes in lighting legislation for the United States. This set up performance standards and the phase-out of incandescent light bulbs in order to require the use of more efficient fluorescent lighting. EISA 2007 is an effort to increase lighting efficiency by 25-30%. Opposition to EISA 2007 is demonstrated by the Better Use of Light Bulbs Act and the Light Bulb Freedom of Choice Act. The efforts to increase lighting efficiency are also demonstrated by the Energy Star program and the increase efficiency goals by 2011 and 2013. A ban on the manufacture and sale of most general purpose incandescent bulbs in the U.S. took effect on August 1, 2023.
