The AS7220 calibrated CCT and lumen maintenance smart lighting manager is equipped with an advanced cognitive lighting engine (CLE) to optimize CCT and lumen and color maintenance via a combination of PWM and/or 0V to 10V controls with dimming ballasts.

Configurable single CCT lifetime target values are stored by the luminaire manufacturer within the attached flash EPROM, or are selectable using an I²C port expander. Target lumen output lux-criteria are similarly configurable and are used by the AS7220 to correlate internal lux to manage PWM mapping to allow automatic compensation for lumen output to be maintained over the life of the light.
