Crescent/Stonco offers energy saving control technology for even greater energy efficiency. New advances in ballast technology now allow dimming of linear fluorescent fixtures for low lighting output during less critical time of day. Motion sensors can also installed to shut off or limit output while areas are unoccupied. Savings can be as high as 50% depending on the amount of light needed during a 24 hour period. Energy saving controls are also used in conjunction with daylight harvesting for maximum benefit.
