The National Environmental Engineering Research Institute (NEERI) in Nagpur was originally established in 1958 as the Central Public Health Engineering Research Institute (CPHERI). [3] It has been described as the "premier and oldest institute in India." [4] It is an institution listed on the Integrated Government Online Directory. [5]
The Board was chaired by the Secretary to the Government of India in the Department of Science and Technology. [2] The Board was set up for promoting basic research in science and engineering and to provide financial assistance to scientists, academic institutions, R&D laboratories, industrial concerns and other agencies for such research.

Advertisement, c. 1890. A Wells light was a large paraffin-fuelled blowlamp used for engineering work, particularly for illumination, in Victorian times. At a time before widespread electrical lighting, they were the most common form of high-powered portable illumination used for construction work, particularly railways, civil engineering, shipyards and ironworks.
The portable or table lamp is probably the most common fixture, found in many homes and offices. The standard lamp and shade that sits on a table is general lighting, while the desk lamp is considered task lighting. Magnifier lamps are also task lighting.

The history of electric light is well documented, [11] and with the developments in lighting technology the profession of lighting developed alongside it. The development of high-efficiency, low-cost fluorescent lamps led to a reliance on electric light and a uniform blanket approach to lighting, but the energy crisis of the 1970s required more design consideration and reinvigorated the use of ...
Illuminants D (1967) represent variations of daylight, illuminant E is the equal-energy illuminant, while illuminants F (2004) represent fluorescent lamps of various composition. There are instructions on how to experimentally produce light sources ("standard sources") corresponding to the older illuminants.
