Control Operating Costs
The Lighting Management System (LMS) Ambient Light Sensor Control turns your canopy and area lights on and off as ambient light conditions dictate. Tests have shown that stores equipped with LMS can save up to an average of 3 hours per day of lighting costs.

As the light begins to wane in the evening, it is not necessary to turn on all your canopy and area lights at once. The LMS allows you to turn on your lighting in stages, according to the level of ambient light. Stage one will allow you to turn on your identification lights and a few canopy lights for security as the sun goes down, or even in overcast conditions. As it grows darker, the rest of your canopy and area lights can be turned on in the LMS second stage. When morning approaches the stage two lights turn off earlier, while the stage one lights remain lit until ambient light increases.

The best part of the LMS is that you can quit worrying about whether or not the lights will be turned on or off at the proper time, since it will always respond to the ambient light conditions to control the lights as you have programmed them. This system can also be used with a timer when 24 hour operation is not needed.

A Phillips 66 study determined that stores equipped with LMS saved nearly 3 hours per day in lighting expenses which led to $100 per month savings in electricity costs (see graph). These savings will very quickly pay for the cost of the LMS and its installation.
