A range of radios from the 1950s

Founded in the early 1900s as a business that renewed burned-out light bulbs, Sylvania and its predecessor companies ultimately began producing new lamps and then vacuum tubes for the fledgling radio industry. By the time Sylvania Electric Products merged with General Telephone in 1959, Sylvania had become a manufacturer of electronics, lighting, television, radio and chemistry and metallurgy. The merged corporation was renamed GT&E Corporation. Sylvania operated as a separate entity and produced cameras, photo flash bulbs, general lighting and TVs and anti missile defense systems. GTE sold its consumer electronics business to North American Philips in 1981.

1993

During the early 1990s it was clear that GTE must make substantial investments into the emerging mobile telecommunications field, which was beginning to compete against its core business in traditional telephone systems. The decision was made to sell off Sylvania to finance these new investments. At this time the global lamps market was dominated by only four players – Sylvania, GE, Philips and Osram, each of whom had roughly a quarter of the market. International monopoly regulations prohibited an outright takeover of the entire of Sylvania by one of these three competitors. Eventually, a deal was struck in which the company was split into two parts. Osram GmbH, obtained the North America, Mexico and Puerto Rican operations and rights to the Sylvania brand in those territories. The remainder of the company in Europe, Asia and Latin America, together with the Sylvania brand in those countries, was the subject of a management buyout which led to the formation of SLI Holdings International LLC. Eventually, The Australia and New Zealand subsidiaries became independent entities. SLI meant Sylvania Lighting International. [2]

2007 to 2016

In April 2007, SLI was acquired by Havells India Ltd. at a transaction price of €227.5 million, forming Havells Sylvania. [3] This newly formed entity has 91 branches and representative offices and 8,000 staff in more than 50 countries.

2016 to present

In January 2016 Havells Sylvania was acquired by Shanghai Feilo Acoustics Co. Ltd. and formed Feilo Sylvania, of which the latter owns 80%. [4] Havells still owns a 20% stake. [5]

Breakthrough Products

Invented together with Bausch & Lomb, this was the world's first light source to feature a cool-beam reflector coating which directs light forwards while allowing heat to escape out of the rear of the lamp. [6]

Following Sylvania's invention of the red-emitting phosphor for colour television screens, a spinoff application created the modern deluxe colour mercury lamp. [7]

Invention of the sodium-scandium lamp chemistry which continues to set the standard for metal halide lighting all over the world. [8]

Invention of The Flashcube allowed still cameras to take four images in succession. It had four electrically fired flash bulbs with an integral reflector in a compact cube-shaped arrangement.

Tru-Aim Professional — The world's first MR16 lamp to feature a sealed front lens and UV protection. [9]

An extremely robust, reliable high intensity discharge lamp (HID) which features dual arc tubes for immediate re-ignition after current interruptions, and more than doubles lamp life to 55,000 hours. [10]

Invention of the first Integrated Circuit ballast for a compact fluorescent lamp – the development responsible for dramatically reducing the size of modern CFL lamps.

The first high voltage halogen lamps which permitted a higher performance upgrade over traditional incandescent reflector lamps.

Invention of the world's first mercury-free HID lamp. [11]

Invention of the world's first compact metal halide lamp in the popular MR16 format, as an energy efficient alternative to the halogen MR16 lamp for commercial lighting. [14]

Introduction of the first compact fluorescent lamps to feature almost instant light at switch-on without reducing lamp lifetime.

The first high efficacy mains voltage halogen reflector lamp, whose 30% energy savings allow the 50W GU10 lamp to be replaced by an efficient 35W alternative with no loss of light.

The world's first LED based retrofit designed to match the performance and size constraints of the popular GU10 50W tungsten halogen lamp, matching the 350-lumen output of the 50W halogen lamp. The lamps are produced at the first LED lamp manufacturing facility in Europe; earlier facilities have been in Asia. The Sylvania RefLED GU10 lamps are manufactured at the plant in Tienen, Belgium, where the world's first GU10 halogen lamp was invented in 1996.

<span class="mw-page-title-main">Electric light</span> Device for producing light from electricity

An electric light, lamp, or light bulb is an electrical component that produces light. It is the most common form of artificial lighting. Lamps usually have a base made of ceramic, metal, glass, or plastic which secures the lamp in the socket of a light fixture, which is often called a "lamp" as well. The electrical connection to the socket may be made with a screw-thread base, two metal pins, two metal caps or a bayonet mount.

<span class="mw-page-title-main">Incandescent light bulb</span> Electric light bulb with a resistively heated wire filament

An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a filament that is heated until it glows. The filament is enclosed in a glass bulb that is either evacuated or filled with inert gas to protect the filament from oxidation. Electric current is supplied to the filament by terminals or wires embedded in the glass. A bulb socket provides mechanical support and electrical connections.

<span class="mw-page-title-main">Halogen lamp</span> Incandescent lamp variety

A halogen lamp is an incandescent lamp consisting of a tungsten filament sealed in a compact transparent envelope that is filled with a mixture of an inert gas and a small amount of a halogen, such as iodine or bromine. The combination of the halogen gas and the tungsten filament produces a halogen-cycle chemical reaction, which redeposits evaporated tungsten on the filament, increasing its life and maintaining the clarity of the envelope. This allows the filament to operate at a higher temperature than a standard incandescent lamp of similar power and operating life; this also produces light with higher luminous efficacy and color temperature. The small size of halogen lamps permits their use in compact optical systems for projectors and illumination. The small glass envelope may be enclosed in a much larger outer glass bulb, which has a lower temperature, protects the inner bulb from contamination, and makes the bulb mechanically more similar to a conventional lamp.

Artificial lighting technology began to be developed tens of thousands of years ago and continues to be refined in the present day.

<span class="mw-page-title-main">Fluorescent lamp</span> Lamp using fluorescence to produce light

A fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. An electric current in the gas excites mercury vapor, which produces short-wave ultraviolet light that then causes a phosphor coating on the inside of the lamp to glow. A fluorescent lamp converts electrical energy into useful light much more efficiently than an incandescent lamp, but is less efficient than most LED lamps. The typical luminous efficacy of fluorescent lighting systems is 50–100 lumens per watt, several times the efficacy of incandescent bulbs with comparable light output. For comparison, the luminous efficiency of an incandescent bulb may only be 16 lumens per watt.

A sodium-vapor lamp is a gas-discharge lamp that uses sodium in an excited state to produce light at a characteristic wavelength near 589 nm.

<span class="mw-page-title-main">Mercury-vapor lamp</span> Light source using an electric arc through mercury vapor

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.

<span class="mw-page-title-main">Compact fluorescent lamp</span> Fluorescent lamps with folded tubes, often with built-in ballast

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.

<span class="mw-page-title-main">Metal-halide lamp</span> Type of 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.

Hydrargyrum medium-arc iodide (HMI) is the trademark name of Osram's brand of metal-halide gas discharge medium arc-length lamp, made specifically for film and entertainment applications. Hydrargyrum comes from the Greek name for the element mercury.

<span class="mw-page-title-main">Light fixture</span> Electrical device with an electric lamp

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.

<span class="mw-page-title-main">Parabolic aluminized reflector</span> Type of electric lamp

A parabolic aluminized reflector lamp is a type of electric lamp that is widely used in commercial, residential, and transportation illumination. It produces a highly directional beam. Usage includes theatrical lighting, locomotive headlamps, aircraft landing lights, and residential and commercial recessed lights.

<span class="mw-page-title-main">Stage lighting instrument</span> Device that emits light to illuminate performers

Stage lighting instruments are used in stage lighting to illuminate theatrical productions, concerts, and other performances taking place in live performance venues. They are also used to light television studios and sound stages.

<span class="mw-page-title-main">Multifaceted reflector</span> Light bulb

A multifaceted reflector light bulb is a reflector housing format for halogen as well as some LED and fluorescent lamps. MR lamps were originally designed for use in slide projectors, but see use in residential lighting and retail lighting as well. They are suited to applications that require directional lighting such as track lighting, recessed ceiling lights, desk lamps, pendant fixtures, landscape lighting, retail display lighting, and bicycle headlights. MR lamps are designated by symbols such as MR16 where the diameter is represented by numerals indicating units of eighths of an inch. Common sizes for general lighting are MR16 and MR11, with MR20 and MR8 used in specialty applications. Many run on low voltage rather than mains voltage alternating current so require a power supply.

<span class="mw-page-title-main">Bi-pin lamp base</span> Type of lamp/lightbulb fitting/connector

A bipin or bi-pin is a type of lamp fitting. They are included in the IEC standard "IEC 60061 Lamp caps and holders together with gauges for the control of interchangeability and safety". They are used on many small incandescent light bulbs, and for starters on some types of fluorescent lights.

<span class="mw-page-title-main">LED lamp</span> Electric light that produces light using LEDs

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.

<span class="mw-page-title-main">Phase-out of incandescent light bulbs</span> For more energy-efficient alternatives

Various governments have passed legislation to phase out manufacturing or importation of incandescent light bulbs for general lighting in favor of more energy-efficient alternatives. The regulations are generally based on efficiency, rather than use of incandescent technology. However, it is not unlawful to continue to buy or sell existing bulbs, which are unregulated.

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.

<span class="mw-page-title-main">Fluorescent lamps and health</span>

Fluorescent lamps have been suggested to affect human health in various ways.

A lightbulb socket, lightbulb holder,light socket, lamp socket or lamp holder is a device which mechanically supports and provides electrical connections for a compatible electric lamp base. Sockets allow lamps to be safely and conveniently replaced (re-lamping). There are many different standards for lampholders, including early de facto standards and later standards created by various standards bodies. Many of the later standards conform to a general coding system in which a socket type is designated by a letter or abbreviation followed by a number.
