Definitions

Ambient Temperature: Average temperature of air or another medium in the vicinity of the luminaire. Ambient temperature is expressed in degrees Celsius.

Luminaire: Apparatus which distributes, filters or transforms the light emitted from one or more lamps and which includes all the parts necessary for fixing and protecting the lamps and, where necessary, circuit auxiliaries together with the means for connecting them to the electric supply. The words “luminaire” and “lamp system” are often assumed to be synonymous. For the purposes of this standard, the word “luminaire” is restricted to apparatus used for distributing light in general lighting, while “lamp system” implies use of lamps in other than general lighting applications.

LED Reported Lifetime: Length of time expressed in hours during which 70% of the measured initial luminous flux value is maintained, as a function of ambient temperature, while not exceeding the reported lifetime as per LM-80.

Lumen Maintenance: Value of the luminous flux at a given time in the life of a luminaire divided by the initial value of the luminous flux of the luminaire and expressed as a percentage “x” of the initial luminous flux value. The lumen maintenance of a luminaire is the effect of decrease of lumen output which is sometimes referred to as depreciation or lumen loss factor.
