According to the Center for Climate and Energy Solutions, lighting accounts for about 11 percent of energy use in residential buildings and 18 percent in commercial buildings. Although there are a lot of energy efficiency options out there, one of the most effective ones are lighting controls. Phasing out old, inefficient lighting can conserve energy and even lower costs.
In general, there are three types of lighting controls. There are dimmers, sensors and timers. Each has different purposes and features. Learn all about the different kinds to see which is right for your building.
Dimmers do exactly what their name states, they dim light. These switches allow for more control than just on and off. With the ability to decrease brightness, dimmers reduce wattage and output, which saves energy and lowers cost.
Pros: Reduces energy consumption, allows for control over brightness, inexpensive.
Cons: Can potentially reduce a light bulb’s efficiency.
Sensor lighting controls turn off and on by the detection of movement. They can be installed indoors, but are particularly useful in outdoor locations to light up areas at night. They, too, are energy efficient by eliminating accidentally leaving the lights on completely. Plus, no one wastes any time trying to find the light switch in a dark room. Sensor lighting controls use body heat and wavelengths so they’re extremely reliable, as well.
Pros: Energy efficient, easy to use, saves time.
Cons: Little control, unwanted shutoff if motion isn’t detected, don’t work well with certain bulbs.
Timer controls are programmable light switches. They can be set so that lights are turned on only during a certain period of time. They are helpful in regulating energy consumption also but just make scheduling easier for your home or building. There are two types of timer lighting controls, manual and in-wall programmable digital timers.
Pros: Increase energy efficiency, good for scheduling.
Cons: Aren’t great to use outdoors because of seasonal changes, may require particular bulbs and lamps.
ON THE BRIGHT SIDE
Installing the right lights in your office or facility has more benefits than just saving energy and money. According to a study by the Journal of Consumer Psychology, bright lights spark emotionally charged responses. By installing dimmers, employees can have the ability to control the brightness of the workplace. The study’s conclusions showed that personal dimming of the brightness of the room may increase employee satisfaction and motivation.
