Motion-Activated Lighting

Motion-activated lighting is perhaps one of the earliest examples of smart home technology.

An enduring staple of sci-fi movies, motion detection first came into play in the 1940s with the first commercial motion sensors brought to market as far back as the 1970s.

Indoor or Outdoor Lighting?

Motion-activated lighting indoors is used for a combination of convenience and energy-efficiency.

You can kiss goodbye to fumbling around in the dark when you’re heading to the bathroom during the night as you get out of bed to dim lights kicking in when the sensors detect you moving around.

If you frequently work late and return home after dark, it’s reassuring to have the lights kick in once you open your lock using your smart phone and enter your brightly illuminated home.

Since lights will only be activated on demand, you can make considerable savings on your electricity bills by investing in motion-activated lighting.

Not only can you save money while making your life easier, motion-activated lighting can also act as a security measure. You can schedule this type of smart lighting to come on and off at pre-set times giving the illusion someone is home even if you’re sunning yourself on a Hawaiian beach.

How Does Motion Activated Lighting Work?

Most smart-activated lighting involves motion sensors that connect to your home hub. These sensors then monitor for any movement in the areas you set up.

Sensitivity settings can be tweaked so you won’t get endless false alarms every time the neighbor’s cat skulks across the lawn or a roaming dog scurries up the path.

Various technologies are used and the passive infrared standard of today has come a long way indeed from the early days of unreliable ultrasonic sensors. Check out our detailed guide on motion sensors for more information on these specific forms of motion sensor technology.

The way in which these sensors work depends to a large extent on whether they’re active or passive.

Active or Passive Sensors?

With active sensors, sometimes referred to as radar-based, sound waves are pinged out into the room then the sensor waits for the signal to come back again. The principle is similar to the way in which garage door openers work.

Whenever anyone enters the protected room or moves around inside it, the speed of those sound waves changes and this triggers the switch.

Passive sensors pick out body heat by means of a photodetector. Light is converted into electrical current which in turn triggers the alarm and activates the switch. Slow changes in temperature due to the amount of natural light coming through the windows are disregarded to minimize false positives.


If you’re opting for a dedicated motion sensor switch, these are designed to replace regular switches and the way in which you wire them varies from manufacturer to manufacturer.

As with all electrical aspects of your smart home, call for qualified assistance unless you’re absolutely confident you can handle the job yourself.

Some switches will call for a neutral wire, also known as a C wire. This is not present in many older homes so you should do your due diligence to avoid any nasty surprises. If you don’t have a neutral wire in place, there’s plenty of motion-activated lighting that doesn’t demand this.

While there are many variables, most installations have 3 wires coming from the motion detector switch:

  • Hot/Power: Black
  • Switch leg: Blue
  • Ground: Green

Indoor Outdoor Motion Activated Lighting Lighting

You can get a wide range of outdoor motion-activated lighting and we’ll give you a glimpse of 3 great options in due course.

Why Use Outdoor Motion-Activated Lighting?

Lighting in the garden that’s only triggered by movement is energy-efficient and you can expect to notice savings on your utility bills and recoup your investment in no time.

If you come home with your hands full, you’ll appreciate the convenience of your pathway being illuminated as you trip the sensor.

Perhaps the leading advantage of outdoor motion-activated lighting is security. Burglars are playing a numbers game and the more difficult you make things for them, the more likely they are to keep on going in search of a softer target.

You’ve got 2 main choices with outdoor motion-activated lighting:

  • Lighting with Integrated Sensor: You won’t need to dig deeper for a separate motion detector with an all-in-one solution. There’s a pretty limited choice of this type of lighting but in return you’ll get a design-driven approach to outdoor lighting with super-simple installation
  • Lighting with External Sensor: The other approach to outdoor lighting is to combine a motion sensor with an LED floodlight to achieve the same result of lights in the garden on demand. You’ll get a broader choice, and you’ll also be able to use multiple lamps with a single sensor as long as overall consumption doesn’t exceed 1000 watts

Placement of Sensor

You can get a wide range of outdoor motion-activated lighting and we’ll give you a glimpse of 3 great options in due course.

Make sure that the area you need protecting falls within these parameters.

Don’t become obsessed with sensors that claim to have a 360-degree detection radius. Often, the sensors will not pick up motion through that entire range.

When you’re considering placement, you should think carefully about detection distance as well. Make sure you’ve got all approaches to your property covered and that the outdoor motion-activated lighting you’re considering fits well with your needs.

Some General Tips When Installing Motion Sensors

Motion detectors are pretty easy to install but installation is still to some extent brand-specific.

Call in an electrician unless you’re extremely confident working with electrics and always kill the power before starting any kind of installation.

Here are some general pointers to think about when you’re installing motion-activated lighting in your garden.

  • Check that your electrical box an all fixtures are grounded before starting out. If not, you might need a new ground wire
  • Make absolutely certain that any equipment you’ll be using outdoors is suitably weatherproofed and won’t end up letting you down in hostile weather conditions
  • Think about locating your fixtures under the eaves to minimize any chance of moisture seeping in
  • Take the time to manipulate the detection distance and angle so you cut down on false alarms. You can also tweak sensitivity settings to make sure your outdoor lighting works for you
  • It’s a smart move to keep bulbs and detectors apart. The heat generated by the bulb is often enough to confuse the sensor so keep them separate if it at all possible
