Advanced Temperature Regulation (ATR) adjusts the output of the EDC31 based on the working and ambient temperatures.

The output measurements account for the total runtime, including periods of reduced brightness due to temperature changes or built-in protection mechanisms, which may cause the brightness level to drop.
