Should I ask my contractor to install light motion sensors in my house to save money?

Light motion sensor switches have been a popular way for companies to save money while being considered more environmentally conscious. This same technology used in commercial applications is available for your home. This simple, efficient and durable lighting approach can stand up to the test of every day usage. So, what are light motion sensors? Indoor light motion sensors will turn the lights on in a room when it detects any motion and will automatically turn the lights off after a certain period of time if there is no motion detected. Seems like a simple principle because it is! But does it work and will it save me money?

One of the concerns many people have is that since it is plugged in – sensing motion all the time, does it use energy? Motion sensing switches do have some phantom energy use. Let’s run a quick scenario, for example, if a motion sensor switch uses about a watt of energy on standby mode for 23 hours a day and 5 watts on active mode for about an hour a day, this could trim a bit off of your overall savings. So what is the real cost, over the course of a month, according to the, the nationwide average of electricity costs $0.12 per kilowatt hour, the switch itself may use up to 0.84 kilowatt hours, or about $0.10 of energy, per month. Compare this with kids or family member leaving the light switch on for hours at a time and this can add up, room by room.

I would recommend these of many areas of your home! Never have to yell, “turn the lights off” anymore! What are areas of the house where you might accidentally leave the lights on for long periods without noticing. Hallways, closets, bedrooms, laundry rooms, utility closets and bathrooms. This is particularly true if there are multiple lights on that switch. Living room and family rooms seem to be two areas where lights get turned on and never turned off, kids walking away into the kitchen or bedrooms, simply leaving the lights on for someone else to turn off.

Let’s look at another example, who many lights are in a light fixture? The light fixture in our guest bedroom has four lights in it. If these all contained sixty (60) watt bulbs and we left it on for a day, the energy use alone would have made the automatic light switch worth it! Or what about your bathroom? Often the bathroom lights are “caught” on, but how many lights are in that fixture, heating up the room and driving up your energy usage? And how many hours per day were they accidentally left on?

Not only can light motion sensors help with the consumption of energy but a few innovations have made them ideal for bathrooms with an added humidity sensor built-in, which can automatically turn of bathroom fans, not only reducing humidity but energy as well. See for more information.

According to the Energy Information Administration (EIA), electricity now accounts for 61% of all energy consumed in commercial buildings. If you translate that percentage to your home, look at your bill and calculate that high percentage and how effective light motion sensors could be. So ask your contractor to install as many energy efficient devices as possible in your home! Light motion sensors can easily be installed in new construction as well as remodels and retrofits.
