Downlight Collar Saves Energy for HID Lighting

Linda Hardesty

Downlight Energy ManageCanada-based Eco-Shift Power has patented a Downlight Collar, which directs light from high intensity discharge (HID) lighting systems in a more efficient pattern.

Testing conducted by the Illuminating Engineering Society (IES) has shown the Downlight Collar can improve efficiency by as much as 15 percent, depending on ceiling heights, says Eco-Shift Power.

The Downlight Collar is a reflective collar that improves thermal isolation of the HID lamp from the ballast. Reduced heat transfer facilitates longer component life, primarily for the ballast and lamp.
