Unlike outdoor motion sensor lights, which focus on providing ample illumination coverage and detecting suspicious activities as a security light, indoor motion sensor lights vary in style, providing convenience, sufficient lighting coverage in compact areas, and adding to your home decoration.<\/p>
What Is a Motion Sensor Light<\/h2>
A motion sensor light is a motion-activated light that has a motion sensor connected to the light bulb or light fixture. When the motion sensor detects people nearby, it will trigger and turn on the light and keep it on for a while. When the motion sensor detects no people around, it will turn off the light to reduce electricity consumption.<\/p>
When we want to have an indoor motion sensor lighting system for our home, we usually utilize motion sensor light switches<\/a> to control the main ceiling lights. A motion sensor light switch is a light switch with a built-in motion sensor, quite similar to how a motion sensor light works. <\/p>
The benefit of using a motion sensor light switch for the ceiling lights is that we can have more direct manual control of the lights on the wall switches. Imagine you’ve installed a motion sensor light on the ceiling, but you have to wait for the light to automatically turn off after the time expires(maybe 10 minutes) with no manual direct control. With a motion sensor light switch, you can instantly turn the light off by pressing the button on the wall switch.<\/p>
With that said above, the indoor motion sensor lights are mostly small and independent lights used in small and compact areas where the ceiling lights cannot provide full illumination coverage or the place where the motion sensor light switch cannot detect. For example, an under cabinet light placed below your home kitchen’s cupboard can be extremely helpful because the ceiling light is somehow blocked by your body and the cupboard that leaving shadows while you are cooking. In the meantime, a regular manual-operated light is not suitable for this situation because your hands are too wet and oily to press the light switch button.<\/p>
How Indoor Motion Sensor Lights Work<\/h2>
A motion sensor light turns on when the motion sensor detects motion and turns off when it no longer detects motion. The motion sensor controls the power to the light, and only when the motions sensor is triggered can the light get power and turn on. <\/p>
So any regular light that connected with a motion sensor can be a motion sensor light. Though many motion sensor lights would have the motion sensor built-in inside the light fixture for integration and direct installation, there are some other great product examples as well.<\/p>
Especially from indoor motion sensor lights, we can see that many products are simply a combination of a light and a PIR motion sensor. Simple ideas but works perfectly well like magic, such as a motion sensor strip light.<\/p>
The indoor motion sensor lights mostly use a passive infrared motion sensor as the motion detector because the PIR motion sensor is highly durable, consistent and cost-effective. The PIR motion sensor can detect motion very well within the range from 20 to 70 ft and turn the light on from 20 seconds to 30 minutes, depending on the setting.<\/p>

Common Features<\/h2>
Indoor motion sensor lights are highly adjustable for users to alter for the best performance. Usually, the common features available in motion sensor lights include: <\/p>
Adjustable Working Modes<\/h3>
Most motion sensor lights are automatic and completely hands-free that you can install, set up and forget about it. They may also provide many practical and user-friendly functions, such as manual mode, dusk to dawn mode and dimming mode.<\/p>
![\"\"](\"https:\/\/rayzeek.com\/wp-content\/uploads\/2022\/02\/014-3.png\")
<\/figure><\/div>The full automatic motion sensor lights are generally used for illumination where people pass by, such as stairs and hallways. You can place the motion sensor lights there and they will work out of the box and you don’t have to worry about them.<\/p>
For some places, such as bedsides and nightstands, where it’s closer to people’s living area, an adjustable motion sensor light can be more valuable. People can make modifications according to their preferences to make the motion sensor light suit their actual needs.<\/p>
Ambient Light<\/h3>
The ambient light feature, also known as the light-sensing feature, is a helpful feature commonly seen in motion sensor lights. These lights would additionally include a light sensor inside the light bulb or light fixture to detect the environmental brightness. In simple words, the light is both a motion sensor and light sensor light. <\/p>
The light sensor compares the LUX of the ambient light to the user-selected value. If the ambient light is bright enough and higher than the light sensor’s LUX value, for example, in the daytime, then the light will stay off no matter the motion sensor detects motion or not. Only when the environment is dark and below the LUX value the motion sensor will activate the light when it detects motion normally.<\/p>
The ambient light feature takes a step further for reducing electricity waste in the daytime. Most motion sensor lights would either have a fixed light sensor value or some levels of per-set LUX value from OFF, 15, 25 to 35 LUX for the users to select. The higher the LUX value, the more energy it can save.<\/p>
Time Delay<\/h3>
When the motion sensor is activated and turns on the light, the light will keep on for some time and then turn off. The time delay is the time period for how long the light is kept ON.<\/p>
Most indoor motion sensor lights allow users to have controls overtime delay, from seconds to minutes. Apparently the shorter the time delay, the more energy the motion sensor light can save. <\/p>
But a short time delay might cause the light to accidentally turns off while you are still in the area if the motion sensor cannot detect your presence very well, which is known as a false-off. A longer time delay may reduce false-offs, but it consumes more power, keeping the light ON. <\/p>
For various applications, the time delay requirement is different. For places where you only need a light when you walk past by, like the lights on the stairs, you can set the timer to a low number. <\/p>
A longer time delay is better for places where you need to spend some time doing things, like in the closet selecting clothes or under the kitchen cupboard cooking.<\/p>
It’s always the best practice to test and alter the time delay until you figure out the best time setting.<\/p>
Sensor Sensitivity<\/h3>
The sensor sensitivity controls for how sensitive the motion sensor is, in other words, for how far the motion sensor can detect movement. Most indoor motion sensor lights would allow users to tailor the setting from low sensitivity to high sensitivity at least.<\/p>
People might wonder why you would set the senility to low, is the high sensitivity not always a good thing? Well, the high sensitivity might cause problems as well. <\/p>
For example, when the light accidentally turns on quite often, even when there are no people around, it’s possible the motion sensor is too sensitive that it is detecting motions that you are not aware of, or it sees you from far away. This false-on would cause unnecessary energy waste, and it could be quite annoying. In this case, set the sensor sensitivity to low.<\/p>
If the motion sensor is not reacting to your movement accurately, a high sensing sensitivity might solve the problem.<\/p>
If the indoor motion sensor light you bought is not available for customizing the sensitivity or detection range, you should spend more time testing and finding the best location to place your lights. With adjustable motion sensor lights, you can put the light where you like first, then alter the sensitivity settings for the best detection performance outcome.<\/p>
Why Use Indoor Motion Sensor Lights<\/h2>
Indoor motion sensor lights are easy to install, supplementary to your main lighting, and they have some great benefits over manual controlled lights:<\/p>
Hands-Free Lifestyle<\/h3>
Motion sensor lights are automatic, work out of the box and require no touch, making them child, elderly and disabled friendly. <\/p>
When you walk into a dark room, you don’t have to go find the light switch. The lights will turn ON for you as soon as you enter the room and shut off after you leave. <\/p>

<\/figure><\/div>Some people might wonder why they would need a motion sensor light if they are so familiar with the layout of their houses and can walk in the dark or quickly find the light switch, but what about your guests and relatives? <\/p>
And no matter how familiar you are with your house, ample illumination is still necessary for some places, such as in your closet and cabinets where you need to look for things. A closet or cabinet motion sensor light can save you a lot of effort with proper illumination.<\/p>
Cutting Electricity Bills<\/h3>
Even if you are aware of saving energy and remember to turn off the light when you don’t use them, there is always some time we will be leaving the lights on without even noticing because the lighting is really an easy thing to neglect, especially in the daytime. <\/p>
Using an indoor motion sensor light with a properly set time-delay and lighting sensor value, you can instantly start saving energy and cutting electricity bills up by at least 30% and sometimes up to 60%.<\/p>
Saving energy could be never this easy with only one simple change in your home lighting plans: upgrading your indoor lights with motion sensor ones.<\/p>
Prevent Injuries in the Night<\/h3>
Night lights, stair lights and bathroom lights can add safety to our home and prevent injuries at night. The children and elderly are less likely to fall or get tripped with the ample lighting for navigation at night. <\/p>
Even for the adults, the motion sensor lights in the storage room and garage can help them get away from getting hurt by the sharp corners or unseen obstacles hiding in the dark.<\/p>
Decorate Your Home<\/h3>
Indoor motion sensor lights, especially strip lights and light bulbs, are incredible decorations to light up your home. With warm lighting or colorful lighting, you can add a more personalized lighting atmosphere to your home life. <\/p>
![\"\"](\"https:\/\/rayzeek.com\/wp-content\/uploads\/2022\/02\/014-4.png\")
<\/figure><\/div>You can place motion sensor strip lights long the stairs, below the steps, or under your bed. With a small time delay, these strip lights won’t cause light pollution at night or ruin your sleepiness after you get up in the middle of the night.<\/p>
Easily Install Everywhere<\/h3>
One last reason why you should start using indoor motion sensor lights is that they are can be installed everywhere in your house. <\/p>
With the stick-anywhere type of lights, the installation is quite easy, and you can attach the light to any wood and metal surface without a problem.<\/p>
