The LightMaster™ control system operates on ambient light level sensing. When natural light is available, the LightMaster™ will allow for this to be used, saving energy costs and ensuring the right amount of light is available. LightMaster™ is an affordable alternative to expensive or unreliable lighting controls and 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 provide savings on maintenance costs over time.
