Since the beginning, light controls have traditionally been used to create moods.Today, they are also used as part of a high quality energy efficient lighting system.This system integrates natural light and electric light as sources to provide a comfortable and well lit environment for the occupants of a room.Electric lighting controls are appropriate for a wide variety of areas, from restrooms to large open offices, from conference rooms to classrooms.Lighting controls incorporated with daylight to provide energy savings and ecological benefits.Although lighting controls are most commonly used in commercial buildings, more and more they are being applied for residential purposes.
Applying occupancy sensors can help reduce energy usage up to 45 percent.Improving energy efficiency can reduce emissions that contribute to global warming, mercury contamination in lakes, acid rain, and nuclear waste.
When people are unlikely to remember to turn lights off, an occupancy sensor is a great way to save money.Depending on wattage, size of area to be sensed, and other features, the cost can range from $50 to $150 per year.Photocells, which are sensors used to help compensate for fluctuations in daylight, cost an average of $10 to $50 a unit.
