This was followed in 1988 by the programmable Golden Scan, a moving mirror projector and the first luminaire to implement stepper motor technology instead of servo motors.

Therefore, it is important that the sciences of light production and luminaire photometrics are balanced with the artistic application of light as a medium in our built environment.
43.
The small source also allows the luminaire to utilize more than 90 % of the available light, compared with 55 % for typical high-intensity discharge fittings.

Ceravision claims the highest Luminaire Efficacy Rating ( LER ) of any light fitting on the market and to have created the first High Efficiency Plasma ( HEP ) lamp.
45.
Extensive luminaire photometric designing calls for consideration of the amount of functional light present, the energy expended, as well as the aesthetic impact supplied by the lighting system.
46.
In 2008, Anastasopoulos designed a Peg Light and received an award for Eskom's Energy Efficient Lighting Design Competition under Category B : Residential luminaire design for professionals.
47.
Lamps and lighting fixtures are tested using goniophotometers and rotating mirror photometers, which keep the photocell stationary at a sufficient distance that the luminaire can be considered a point source.
48.
According to a radio interview with the Klaxons, the name " Golden Skans " is derived from a performance luminaire, the " Golden Scan " manufactured by Clay Paky.
49.
The LED drivers can be put inside lamp or luminaire, which is called a built-in type, or be put outside, which is called an independent type.
50.
Presently, the following luminaire types are available on the market : Cobra head, shoe-box, high bay, low bay, canopy, aquarium, and architectural.
