  • Replacing your Metal Halide or High Pressure Sodium (HID) light fixtures with fluorescent fixtures can save up to 50% in energy costs. Fluorescent lights boast higher lumens per watt efficiency, instant on capabilities for better lighting control, consistent lumen output over time, and a higher color rendering index than HID lighting. You can save money and improve the quality of light delivered to your work surfaces. It all adds up to a great lighting alternative.
  • Astronomic timers can improve control of outside site lights. They are not affected by weather and automatically change daily with the time of sunrise and sunset. Not only will this reduce electrical consumption but also demand charges created by lights turned on during the on-peak billing hours of the day when skies are dark and stormy. In addition, lights can be cycled off for portions of the night hours if not needed.


Retrofits vs. Replacements - Much of the energy savings in a lighting upgrade can often be realized without replacing the entire fixture. Replacement of just the lamp and or ballast is called a retrofit. Fixture replacement is sometimes necessary due to poor condition, lighting needs change, technology change or when fewer lamps per fixture can achieve improved energy savings. Cost and savings of options can help with your evaluation.

Group Re-lamping of lighting fixtures is a cost-effective lamp replacement method for HID and fluorescent lighting. By group re-lamping your facility, maximum light output can be maintained with minimum interruption from lamp failures. Re-lamping at vendor-prescribed intervals is important to productivity and safety, and prevents more expensive use of additional lighting as light levels gradually depreciate.

Magnetic Ballasts - Department of Energy rules require a phase out of magnetic ballasts (see, 10 CFR Part 430; “Energy Conservation Program for Consumer Products: Fluorescent Lamp Ballasts Energy Conservation Standards”). After June 30, 2010, fluorescent lamp systems must use electronic ballasts for spot replacement. This presents an opportunity to consider upgrading your T12 fluorescent lighting systems with magnetic ballasts to more efficient T8 lighting with electronic ballasts helping pay for the upgrade through energy saving. It is recommended you review the rule for further guidance and how it applies to your facility.

Controls - A wide range of controls are available that include occupancy sensors, photo sensors, energy management systems, automatic dimming, timers, wireless switching and bi-level switching. A control system should be chosen that best matches your control needs providing the right amount of light only when you need it with flexibility to adapt to changing work environments.

Painting Walls and Ceilings a light color such as white will reflect more light to the work surface. As a result light levels will increase or the number of lights required can be reduced to save energy.

Keeping Fixtures Clean helps maintain light levels at original intended levels. A good time to clean a light fixture is during normal re-lamping. Dusty or smoky environments may require more frequent cleaning.

Daylight Harvesting is dimming of indoor perimeter lighting near windows where natural light additions are available to save energy. This can be accomplished with dimmable ballasts or by reducing the number of lights on in a fixture using automatic photo sensing controls. Make sure your zones of control match your daylight coverage and locate your light sensor carefully.

Replacement Lamps must be specified to match the installed ballast. This applies to ballasted fixtures such as fluorescent and HID light fixtures. Lamps and ballasts work together and if mismatched, ballast life or lamp life can degrade.
