You know the story. There’s a jewel robbery happening. After intense planning, the thief infiltrates the museum, probably through an air conditioning vent. When he drops down into the main room he’s still got to navigate the motion sensing security system, slinking under, over, and between beams of light. Perhaps he makes it through, and puts the biggest diamond you’ve ever seen in a shabby sack, ready to make the getaway. Suddenly, he slips, or drops the bag, and activates the sensor by a thread. Foiled! The bad guys get caught and the museum keeps their precious jewel.
While you may not have any multi-million dollar rocks in need of serious protection, motion sensor lights can help you in a ton of different ways. They’re convenient, safe, and will save energy.
Unlike the classic museum sensors that use light to detect motion, most motion sensor lights use PIR (passive infrared) or pyroelectric sensors. These systems detect rapid changes in infrared energy, and thus can turn on the lights when people, animals, or cars approach.
While having every light you own set on a motion sensor might not be a good idea (I foresee superfluous arm waving), select motion-controlled lights can be an invaluable addition to your home or office. Here are a few ways to use them:
- Outdoor Lights: If you find yourself stumbling up the front steps with grocery bags after dark, installing a motion sensor spotlight or a few step lights could make the difference between getting inside safely and taking a dangerous spill. Putting flood lights on a sensor will also make navigating your yard and driveway more secure, helping you see and deterring any intruders.
- Night Lights: Opting for a motion detector night light will help you save energy – only turning the light on when you need it. If you wake up in the night for a snack or a trip to the bathroom, these lights are also one of the gentlest ways to help yourself see – you don’t get blasted with the full lumens of your overhead light source, and you don’t even have to think about flipping a switch.
