The LESS lighting system can save over 50% on energy costs through three key features: 1) efficient "Daytronic" ballasts that allow dimming, 2) occupancy sensors that turn lights off when unoccupied, and 3) daylight harvesting sensors that adjust light intensity based on natural light levels. LESS resolves common issues with conventional fluorescent lighting by bringing intelligence to existing lighting systems through retrofitting to provide comfortable and energy efficient lighting.
