Pyrex is a brand introduced by Corning Inc. in 1915 for a line of clear, low-thermal-expansion borosilicate glass used for laboratory glassware and kitchenware. It was later expanded to include ware products made of soda-lime glass and other materials.
Cooper Industries was an American worldwide electrical products manufacturer headquartered in Houston, Texas. Founded in 1833, the company had seven operating divisions including Bussmann electrical and electronic fuses; Crouse-Hinds and CEAG explosion-proof electrical equipment; Halo and Metalux lighting fixtures; and Kyle and McGraw-Edison power systems products.
Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion, making them more resistant to thermal shock than any other common glass. Such glass is subjected to less thermal stress and can withstand temperature differentials without fracturing of about 165 °C (297 °F). It is commonly used for the construction of reagent bottles and flasks as well as lighting, electronics and cookware.
Ellipsoidal reflector spot is the name for a type of stage lighting instrument, named for the ellipsoidal reflector used to collect and direct the light through a barrel that contains a lens or lens train. The optics of an ERS instrument are roughly similar to those of a 35 mm slide projector. There are many types of ERS that are designed for the myriad applications found in the entertainment industry. ERS instruments come in all shapes and sizes. Each particular model of ERS has its own set of characteristics. Generally, ERS instruments are the most varied and utilized type of stage lighting instrument. ERS may also be referred to as Profile Spotlights because the beam can be shaped to the profile of an object. Ellipsoidal reflectors are used for their strong, well-defined light and their versatility. Leko and Source Four are brand names which are often, but inaccurately, used to refer to any sort of ellipsoidal.
Schott AG is a German multinational glass company specializing in the manufacture of glass and glass-ceramics. Headquartered in Mainz, Germany, it is owned by the Carl Zeiss Foundation. The company's founder and namesake, Otto Schott, is credited with the invention of borosilicate glass.
Corelle Brands, LLC is an American kitchenware products maker and distributor based in Rosemont, Illinois.
A sight glass or water gauge is a type of level sensor, a transparent tube through which the operator of a tank or boiler can observe the level of liquid contained within.
Friedrich Otto Schott (1851–1935) was a German chemist, glass technologist, and the inventor of borosilicate glass. Schott systematically investigated the relationship between the chemical composition of the glass and its properties. In this way, he solved fundamental problems in glass properties, identifying compositions with optical properties that approach the theoretical limit. Schott's findings were a major advance in the optics for microscopy and optical astronomy. His work has been described as "a watershed in the history of glass composition".
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.
Automotive Components Holdings, LLC is a Ford Motor Company-managed temporary business formed by the 2005 transfer of 17 automotive components factories and six research, testing and other facilities from Visteon Corporation to Ford. The creation of ACH was intended to ensure that Ford continued to receive a flow of parts from the facilities, whilst enabling them to be prepared for sale or other disposition.
The Electronic Theatre Controls (ETC) Source Four is an ellipsoidal reflector spotlight (ERS) used in stage lighting. First released in 1992, the Source Four was invented by David Cunningham and features an improved lamp and reflector compared to previous ERS designs, tool-free lamp adjustment, and a rotating, interchangeable shutter barrel. The Source Four is widely used by professional theaters across the globe.
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.
Acuity Brands, Inc. is a lighting and building management firm headquartered in Atlanta, Georgia, with operations throughout North America and in Europe and Asia. It currently has about 13,000 employees and recorded net sales of $3.7 billion for fiscal year 2018. In terms of market share, Acuity Brands is the largest lighting manufacturer in North America.
The A.H. Heisey Company was formed in Newark, Ohio, in 1895 by A.H. Heisey. The factory provided fine quality glass tableware and decorative glass figurines. Both pressed and blown glassware were made in a wide variety of patterns and colors. The company also made glass automobile headlights and Holophane Glassware lighting fixtures. The company was operated by Heisey and his sons until 1957, when the factory closed.
In photography and cinematography, a reflector is an improvised or specialised reflective surface used to redirect light towards a given subject or scene.
Sky-Watcher is a commercial distribution company established in 1999 by the Synta Technology Corporation of Taiwan that markets telescopes and astronomical equipment, like mounts and eyepieces, aimed at the amateur astronomical market. The products are manufactured at Synta Taiwan's Suzhou Synta Optical Technology Co., Ltd. in Suzhou (Jiangsu), China. The brand is distributed in Canada and Europe and, in the late 2000s, extended to the USA market.
The Sneath Glass Company was an American manufacturer of glass and glassware. After a brief 1890s startup in Tiffin, Ohio, the Company moved to Hartford City, Indiana, to take advantage of the Indiana Gas Boom. The small city was enjoying the benefits of the boom, and could provide natural gas as an energy source for manufacturers. Sneath Glass was one of many glass manufacturers that moved to the region, and became Hartford City's second largest employer.
Benjamin Electric Manufacturing Company was a Des Plaines, Illinois electrical company founded in the late 19th century.
Havells Sylvania and formerly 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.
