The ACI A/LLS Series Light Level Sensor is used to control indoor and outdoor lighting based on available light. The sensors can be installed in a NEMA 3R enclosure, with resistance exceeding 1 MΩ in darkness and dropping below 1.5 kΩ in bright light.

The A/LLS-T includes a transmitter that provides a non-linear 4–20 mA output, calibrated to 4 mA in darkness and 20 mA in bright light. The 0–500 model is typically used for outdoor parking lot lighting and signage, while the 0–100 model is intended for indoor lighting. Both models are suitable for lighting control and building automation systems.
