The LM2-0-120 operates on ambient light level sensing. LightMaster is an affordable alternative to expensive or unreliable lighting controls. It is a cost effective solution for providing additional light level control beyond the typical timer or photo control. It can be added to an existing timer. LightMaster offers true dusk-to-dawn operation and can achieve additional energy savings by adjusting light levels throughout the day or night. Additionally, it offers an affordable solution for daylight harvesting. The LightMaster features a delay setting to avoid nuisance ON/OFF switching of lighting during intermittent environmental changes, such as clouds, lightning, or headlights. The LightMaster is essential where activities are impacted by changing and inadequate light levels throughout the day. It will turn lighting ON during inclement weather and OFF when normal light levels resume. The LightMaster is more reliable than photo controls and can save maintenance
