Let’s shed a little motion-sensitive light on motion-sensitive light
Motion Sensors Light Guide 2023
Some lights automatically go on when you enter a room or step onto a front porch. When that happens, motion sensor lights are in play.
If you wish you had some of that technology for your own, well, you can. Keep reading to learn more about motion sensor lights and how you can get them.
How do motion sensor lights work?
Let’s talk about how a motion sensor light works.
To have a motion sensor light, you first need a motion sensor, aka a motion detector. There are a few different types of motion detectors, such as the following:
- Passive infrared (PIR)
- Active infrared (sometimes also called area reflective)
- Dual technology
Check out our motion sensors guide for more information.
Motion sensors lights
As we mentioned before, a motion sensor light is turned on by the motion sensor. That usually means that the light will automatically turn on as soon as this sensor (also called an occupancy sensor) notices you.
Typically, the light remains on either for a set time or as long as it senses the movement. If you’ve ever sat on a public toilet and the bathroom light suddenly turned off, you probably know what we’re talking about.
Do you need motion sensor lights?
A motion sensor light can make you feel like you’re truly living in the future. But that doesn’t mean everyone needs to purchase them willy-nilly.
Here are some typical reasons you might want to consider buying motion sensor lights.
You like convenience.
Imagine never flipping a light switch again. If that sounds appealing, motion-sensitive lights await you.
You want to save energy.
No more leaving the lights on. If no one’s around, your home will stay dark.
You want to discourage prowlers and thieves.
Outdoor motion sensor lights (especially if they’re floodlights or spotlights) can deter criminals. Without darkness to cover their tracks, they may flee from your home.
Motion sensor lights can also be useful for some people with disabilities.
What features should you look for in motion sensor lights?
There’s a lot to think about when it comes to choosing a motion sensor light.
There are several different types of bulbs on the market.
- LED (light-emitting diode): Light is produced by diodes, a component with electrodes that electricity passes through
- Incandescent: Light is produced by a heated wire filament²
- Fluorescent: Light is produced by a chemical reaction³
There are pros and cons to each bulb type. For instance, LED lights tend to last longer than incandescent lights, but they also cost a lot more than most incandescent lights.⁴
Most outdoor lights come with a particular bulb type already installed, while most indoor lights are just a single bulb. So if you have a strong opinion about which bulb to use, make sure to check the light specs before you buy.
A halogen light or halogen lamp is a type of incandescent light.⁵
Do you want a typical light pattern that gently disperses throughout a room or yard? Or would you like a floodlight (that illuminates a large space) or a spotlight (that puts an intense focus on one person or object)?
If you’re getting a light for security purposes, a floodlight or spotlight is probably the best choice. But if you aren’t looking for anything special, a generic pattern ought to do ya.
Your three choices are usually battery-operated lights, wired lights, or solar-powered lights. You might also come across a combination light that uses multiple sources.
Figuring out the right power source will depend on your climate and desired light placement.
Where do you get motion sensor lights?
Unlike regular motion sensors, motion sensor lights aren’t a staple of home security kits. Most home security companies don’t even sell standalone motion sensor lights (although they should). You usually have to buy them on their own.

You should put a light outdoors only if the manufacturer specifically says it’s for outdoor use. Otherwise, it’s probably not weatherproof and will be destroyed by heat, cold, precipitation, or wind.

If you’re looking for something from a security brand, the best suggestion we can offer is a Ring motion sensor. This sensor connects to Ring smart lights, effectively turning them motion-sensitive. You just need a Ring Bridge to pull it all together.
How do you install motion sensor lights?
Installation methods for lights will depend largely on the light you purchase. Usually, the manufacturer provides some instructions.
But to get you on your way, here’s a really broad idea of what installation might be like.
Replacing an existing light
If you’re replacing an existing light bulb, that’s incredibly easy. It will look something like the following:
- Turn off power to the socket.
- Wait for the existing bulb to cool.
- Twist the existing bulb out of the socket.
- Screw the new bulb into the socket.
- Turn the power back on.
If you’re replacing an existing hardwired or mounted light fixture, that will be a little trickier. Again, the manufacturer should provide instructions.
If you have to tap into your home’s wires and don’t have previous electrical experience, we strongly recommend seeking professional assistance.
Adding a brand-new light
Completely installing a brand-new fixture in a spot where one didn’t exist may, again, require electrical experience.
If you’re installing a light outdoors, make sure to weatherproof any wires or cords. You don’t want to ruin or short the light, and you especially don’t want any electrical accidents.
How do you get home automation support for your motion sensor lights?
It was tough for us to find motion-detector lights that directly work with any smart home assistants or protocols. The lights with the most automation were non-motion smart lights that can connect to an additional motion sensor.
Recap: How to choose a motion sensor light
Now that you know the facts about motion sensors, you might be interested in buying one. Let’s quickly walk through the process you’ll need to follow.
Decide whether you need a motion sensor light: Look at your circumstances and decide if you could use a motion-sensitive light for safety or convenience.
Choose a light: Look at location, bulb type, light pattern, and power source to choose the best possible light.
Install your light: Follow the manufacturer’s instructions to securely install your new light.
Connect the light to your smart home: This doesn’t apply to most motion detector lights, which sadly lack home automation. If your light has a separate motion sensor, it’s more likely to connect to the broader smart home.
