How it works

A Green Ballast may look like an ordinary ballast, but it offers the highest fluorescent lighting energy reduction available short of turning the lights off.

The difference is both inside and outside the ballast. Each Green Ballast includes a photocell sensor that interacts with our daylight harvesting technology, allowing each Green Ballast equipped fixture to:

• Actively measure the amount of daylight in its coverage area
• Harvest this daylight and calculate how much fluorescent light is actually needed to provide adequate lighting
• Adjust the power consumption of the lighting fixture accordingly

This is an active and continuous process that works independently fixture by fixture, room by room. All controls are automatic, insuring energy savings while maintaining quality lighting for a productive, comfortable and user-friendly environment.

Green Ballast products work as well in a 1,500 square foot retail location as they do in a 1,500,000 square foot commercial office building.   

Green Ballast products maximize fluorescent lighting energy reduction and, depending on your building’s exposure to natural light, can save as much as 70% on your lighting costs.

Green Ballast versus other Daylight Harvesting solutions. 

The technology that enables our photocell sensor to interact with our ballast is patented by Green Ballast. Other manufacturers offer centrally controlled daylight harvesting solutions, but only Green Ballast products allow each fixture to operate truly independently. Not only do Green Ballast equipped fixtures operate more efficiently and accurately, installation is also less expensive. 

Your building maintenance personnel or lighting professionals will find upgrading with Green Ballast products to be a simple, plug and play installation. Simply remove the old ballast, tune the Green Ballast, and connect the photocell. Green Ballast is ready to save energy and money.

Depending on available conservation incentive rebates, upgrading with Green Ballast products can payback in 6 to 36 months with a life expectancy of up to 12 years.
