The Alliance Center replaced over 1,000 40-watt T-12 fluorescent lamps and magnetic ballasts. Using the same fixtures, 32-watt T-8 lamps and high efficiency electronic ballasts were installed. By reducing energy consumption for lighting by over 40%, the cost for the retrofit will pay for itself in 2½ years. The new lamps contain 50% less mercury and phosphorus, so they don’t have to be disposed of as hazardous waste.
Benefits of this ballast:
- It is dimmable- either by the automatic sensor or by manual settings.
- Maximum output of light can be limited by setting switches in the ballast so that offices will not be over lit and energy will be saved.
- By allowing a precise light level setting and “harvesting daylight”, the power consumption of these fixtures is reduced by 30 % to 50% over current building standards.
