Lighting Control

Lighting controls saves energy costs in homes, commercial offices, warehouses and factory floors. Facility managers and business owners are realizing that lighting controls are necessary, because they directly impact and improve the bottom line, without much financial investment and installation costs.


Reduce your lighting cost on your home by purchasing dimmers and occupancy sensors. Frost's full inventory includes everything from single wall dimmers and occupancy sensors to whole house dimming & switching systems.

  • Installing one dimmer in every US home in place of a standard light switch would save $230 million in electricity per year and reduce CO2 by 4.3 billion pounds a year
  • Lighting accounts for about 20% of an average home's electricity bill.
  • Incandescent bulbs last 20x longer if dimmed by 50%.

Commercial Office, Warehouse and Factory Floor

With mandatory energy code requirements on the state, regional, and local levels, virtually every facility faces lighting control issues. Frost has everything need to reduce usage or wattage of your lighting fixtures and systems. Lighting uses the greatest amount of energy in many facilities and installing dimmers, occupancy sensors, time clocks and photo-controls can result in large money saving opportunities.

Occupancy Sensors

Wall-box mounted occupancy sensors can replace light switches for lighting control in a specified area. Likewise, occupancy sensors in combination with light switches provide user override is desired. Combination technology, sometimes referred to as dual technology, sensors use both passive infrared and ultrasonic sensing to reduce false trigger or vacancy problems and provide an even higher level of efficiency.

  • Occupancy sensors have a three-year payback in rooms that use more than 200 watts of lighting and are in use less than six hours a day.
  • Occupancy sensors reduce energy usage by approximately 30%


Dimmer switches save energy when full illumination is not required. To dim fluorescent lamps effectively and reliably, dimmer switches must be tied into dimmable ballasts. High-efficiency electronic ballasts provide the same level of light output as standard electronic ballasts while using less energy. These ballasts reduce the lighting power required for florescent lamps by about 3 watts.

  • Dimming controls are installed in 18% of new construction projects and 15% of retrofit projects.

Bi-Level Switches

Bi-Level switching simply means having two light switches for a room rather than one. For example, one light switch in a conference room controls one-third of the lights while the other controls the remaining two-thirds. Depending on the lighting required, just one or both switches can be turned on to give three different lighting levels.

  • 55% of new construction projects and 49% of retrofit projects specify bi-level switching


Scheduling, or time sweep controls, automatically shuts lights off according to prescribed occupancy schedules.

  • Time sweep controls are installed in 42% of new construction projects and 30% of retrofit projects.

Control Systems

Lighting control systems can be programmed to control a multitude of lighting circuits, each with its own set of time sweeps, daylighting variations, multiple levels, special-event scheduling, and manual-override capabilities. These systems are especially useful when multiple zones require varying time-sweep controls.


Daylight Harvesting

Before the advent of electric lighting, daylighting was an important way to provide light inside the built environment. Increasing emphasis on energy efficiency and overall sustainability, along with an understanding of health and productivity benefits, has brought daylighting back to the forefront of interior lighting design. When implemented properly, daylight harvesting can save energy and increase the quality of light inside a building. All of the lighting controls
described on this page can be used to adjust electric lighting levels based on the amount of daylight in a given space.

Advanced lighting control systems also incorporate daylight harvesting features. The Lighting Controls Association website offers free educational and product resources to help understand the benefits of these systems.

  • Turning off lights when adequate daylighting levels are present produces energy saving in warehouses up to 70%

Did You Know?

  • Dimming lights by one quarter can reduce your total electricity expense at least 20%
  • Occupancy sensors can deliver as much as 50% of energy costs in a classroom and almost 30% in a private office
  • Daylight harvesting controls and automatic window shade systems can reduce energy costs by as much as 40%

With six branches, Frost conveniently offers the St. Louis metro area along with Mid-Missouri state of the art lighting control technology to maximize energy efficiency at your home, office or warehouse facility.
