Scheduling also allows you to vary the times when the lights go on and off throughout the week so that no day repeats and becomes predictable to someone casing your house. And devices such as Philips Hue smart bulbs and the LIFX + BR30 outdoor bulb let you schedule them to go on with different brightness levels and in different colors. These devices also allow for grouping, so you can turn several lights on or off simultaneously with one schedule, tap, or voice command.

Get motion-activated lighting

Keeping lights on 24/7 not only alerts criminals that you’re not home but also can make it easier for potential burglars to find a clear path to doors and windows. In some neighborhoods it’s easy to tell who’s on vacation by the porch lights left on during the day. Jordan Frankel, security expert and vice president of Global Security Operations, recommends using motion-triggered lighting, which turns on when it detects motion and turns off after a set period of time. “It will startle an intruder, as they have no idea if it was a homeowner who flipped on a light switch or if it was motion detection,” he said.

Wirecutter recommends the Sengled Smart PAR38 LED Bulb, which is outdoor-rated to resist moisture and has a customizable motion sensor built right into the bulb. When triggered, it produces 1,200 lumens, a little brighter than a typical 75-watt-equivalent LED light bulb. Unlike standard motion-sensor lights, you can adjust the sensitivity in this bulb’s app so that it doesn’t trigger whenever a large moth flits by.

It should work with most outdoor fixtures, though Sergeant Michael Lambert of the Dallas Police Department always recommends pointing the light down for best results. “It gives you the brightest view, because it’s hitting the ground and expanding out, instead of shooting up, going toward the sky,” he said. If you don’t have an existing outdoor fixture, or if you want motion-triggered lights along a pathway, Wirecutter also recommends Ring Pathlights.

You can combine most smart lighting options with separate motion sensors for the same result — and at the same time curb instances of lights staying on when not in use. (We have smart-sensor recommendations that work with Amazon Alexa, Apple HomeKit and Samsung SmartThings.)

Mimic daily activities

Choosing a set time for lighting to go on and off can deter criminals, but a burglar who stakes out your house will quickly notice after a day or two if certain lights go off at exactly the same time every day. Unlike a plain timer, many smart lighting devices provide an “away” mode, which turns lights on and off randomly during a set period and makes it seem as if someone is home and moving room to room.

Smart plugs are devices you insert into an outlet to turn any lamp into a smart one. Putting a few around your house and setting the lamps to go on and off randomly when you’re away is a fast, painless and relatively inexpensive solution. Look for plugs like the Wirecutter-recommended Wemo Mini and the TP-Link HS105, which have away modes but can also work on a set schedule.
