Why You Should Use a Motion Sensor Light Switch<\/h2>
If you are reading this guide, you might already want or are willing to buy a motion sensor light switch. We’re all aware that using a motion sensor light switch can reduce energy waste and cut your electricity bill, but a motion sensor switch can benefit you way more than you imagine compared to a regular light switch.<\/p>

Here are some major advantages of using a sensing-based light switch.<\/p>
Save Energy and Reduce Electricity Waste<\/h3>
It’s common sense that a motion-activated light can save more energy than a manual-operated light, but how much energy can motion sensor light switches save indeed?<\/p>
According to CEE, motion sensor light switches can save up to 60% energy in-home laundry rooms.<\/p>
According to the Lawrence Berkeley National Laboratory, occupancy-based strategies(occupancy sensor and vacancy sensor light switches) can produce average lighting energy savings of 24%.<\/p>

<\/figure><\/div>According to the US Environmental Protection Agency, By using automatic shutoff, scheduled shutoff strategies like motion sensor switches, energy savings can range from 40% to 46% in classrooms, 13% to 50% in private offices, 30% to 90% in restrooms, 22% to 65% in conference rooms, 30% to 80% in corridors, and 45% to 80% in storage areas. <\/p>
On average, motion sensor light switches can save 30% to 60% lighting energy in residential and commercial applications, some even up to 80% energy saving. <\/p>
Longer Lifespan for LED Lights<\/h3>
Like all electronic products, many of us will wonder the frequent On and OFF may do more damage to the light’s lifespan rather than expand it by reducing its working hours.<\/p>
Whether repeatedly turning the light on and off damages it depends on what type of light bulb you use. Frequently On&OFF results differently for incandescent and halogen bulbs, fluorescent bulbs ad LED lights. <\/p>
Let’s look at the suggestions on when to turn off your lights from the U.S. Dept. of Energy:<\/p>
- It is best to turn off incandescent and halogen bulbs whenever they are not needed due to their high electricity consumption.<\/li>\n\n
- For a compact fluorescent bulb, a rule of thumb is to leave it on if you leave a room for 15 minutes or less (depending on several factors).<\/li>\n\n
- For LED lighting, the operating life is unaffected by turning it on and off.<\/li><\/ul>
With these conclusions in mind, let’s dig into how these lights work in theory to understand better.<\/p>
Halogen, incandescent and fluorescent lights all use tungsten filaments that heat up and emit electrons via thermionic emission.<\/p>
Basically, a bi-metallic switch heats up and opens periodically, causing the magnetic field generated by the ballast to collapse and release an inductive kick into the tube. If the kick isn’t strong enough, there won’t be enough electrons to sustain the circuit through the tube and the light will flicker. The light will only sustain when the magnetic field is strong when it collapses.<\/p>
![\"\"](\"https:\/\/rayzeek.com\/wp-content\/uploads\/2021\/11\/light-bulbs.jpg\")
<\/figure><\/div>The idea is that the tungsten element undergoes thermal shock every time the light is turned on. Turning on the light every time does damage the filament and will result in long-term damage.<\/p>
LED light is the only type of light-emitting device out of the list that doesn’t use a tungsten element. It uses a PN junction instead, which means that the LED light requires much less voltage and current, meaning low power consumption compared to the lights with filaments. As such, LED won’t be damaged at all by switching since there is no filament to damage and the power going through the bulb is lower. In fact, many applications switch them at high speeds using PWM, which they handle with no problem.<\/p>
For Halogen, incandescent and fluorescent lights, even though it shortens their lifespan every time they are turned on and off, but it’s still better than leaving the lights on 24\/7. So using a motion sensor light switch can definitely help save cost and evergy in the long run.<\/p>
For LED lights, their lifespan is extended with shorter working hours and the energy cost is reduced with a motion sensor switch.<\/p>
For whatever type of light, applying a motion-activated light switch can do more benefits than damage, especially for LED lights.<\/p>
Convenient, Clean and Hands-free<\/h3>
When your hands are dirty in the kitchen, wet in the bathroom or arms-full in the garage, a hands-free lighting control solution is the real problem solver. We’ve all been to similar situations where we need to go back to turn off the light when we’re not able to turn it off while leaving the room because of oily or occupied hands.<\/p>
