non-calibrated
Balanced tunableWhite
–
Manual control two colour
temperature ranges
–
Colour temperature between 2700 K
and 6500 K
–
Brightness and/or light output depends on
the control the light colours
–
Greater tolerances with MacAdams levels
–
Controlled via DALI device type or
two separate channels
Calibrated tunableWhite

Control calibrated (pre-set) colour
temperatures
–
Colour temperatures near the
Planck curve within MacAdams levels
–
