Light CTL models

The Color-Tunable Light (CTL) models allow remote control and configuration of CTLs on a mesh device.

The Light CTL models can represent the lightness states on a linear or preceptually uniform lightness scale. See Light Lightness models for details.

The Light CTL models also feature their own common types, listed below. For types common to all models, see Bluetooth mesh models.

• Light CTL Server
