task tuning

[13.3.3] The practice of adjusting the maximum luminous flux and/or the spectral power distribution of the luminaires in a space to a desired target illuminance and/or spectrum in support of […]

personal tuning

[13.3.4] The ability of occupants in a space to adjust the luminous flux and/or spectral power distribution of luminaires according to their personal preferences.

vacancy sensor

[13.2.3] A type of occupancy sensor that requires the luminaires to be turned on manually.

tunable lighting

[13.3] The ability to alter the luminous flux and/or spectral power distribution of a lamp or luminaire.

spectral tuning

[13.3.1] Adjustment of a light source spectrum in response to task, space, or occupant needs. NOTE: This term was modified in ANSI/IES RP-16-17 Addendum 3.

color tuning

[13.3.5] Color tuning is one use of spectral tuning.   Note: This term was added in ANSI/IES LS-1-21.


[13.3.2] The ability to change the luminous flux of one or more lamps or luminaires.

lighting zone (interior lighting controls)

[13.1] In interior lighting controls: Any number of individual luminaires in a space that, when combined, form a logical control group.  (Sometimes called a control channel or a lighting control […]

adaptive lighting

[13.2.1] Lighting with the ability to automatically adjust light level and spectral content based on environmental conditions in order to optimize space, human, and  building performance.

occupancy sensor

[13.2.2] A control device that detects occupant presence and automatically turns luminaires and/or other equipment on and, after a preset delay during which no presence is detected, turns them off. […]
