﻿Each HCL matrix contains the settings for the brightness (0...100%) for each full hour of the day (0:00 midnight, 1:00 a.m., 2:00 a.m....11:00 p.m.).
Depending on the time of day, the individual brightness values are called up one after the other as the day colour temperature sequence progresses.
The values between two full hours are determined continuously every minute by linear interpolation to implement a smooth brightness progression.

In an HCL matrix, separate brightness values are always configured for each time. Whether a group or single device reacts only to the pre-programmed colour temperature or additionally to the defined brightness value is defined by the parameter "Type of daytime colour temperature sequence" on the parameter pages of the groups and single devices.

The brightness values stored in a HCL matrix can always be configured within the range of 0...100%.
If HCL values are outside the range defined by the minimum and maximum brightness of assigned groups or single devices, the gateway limits the brightness to the defined limits when a daytime colour temperature sequence is running.

The "brightness" parameters are available for each full hour of an HCL matrix. The default setting of the parameters depends on the time.
