Brighten or dim your facility or workstation's light from a control panel. These dimmers fit through a standard panel cutout. Lightly press and hold your finger to adjust the light level. Rated IP67, these dimmers are so watertight they could even handle brief submersion. They also seal out dust.

Dimmers are great if you want to control the brightness from one place but turn the light on or off from a switch somewhere else. For example, you might want to dim a light over your storage area from a main control panel for energy efficiency but still be able to turn it on or off when you enter the area.

Adjust how bright lights are from anywhere. These dimmers use Wi-Fi to sync to a downloadable app on your smartphone or tablet. Use the app to set the brightness, turn lights on and off, and set a lighting schedule. For example, you might set the light to dim during peak sunlight hours. Someone working in the area is still able to turn the brightness up by pressing the top push button on the dimmer. Use up to 20 of these dimmers—even if they’re across different circuits—on the same Wi-Fi network.

Often used in large, open workspaces, these dimmers can be wired on opposite ends of the room to control the brightness of lights on the same circuit.

Control the brightness of lights from your smartphone. Using a Bluetooth-connected app on your phone or tablet, you can schedule when lights turn on, adjust their brightness levels, and set their movement sensitivity. Also known as occupancy sensors, these dimmers turn lights on when motion is detected and off when people are away. You can override the motion sensor function with a tap on the app to manually switch or dim lights. They fit in standard wall plates.

Dimmers with infrared sensors detect changes in heat sources and require a direct view of people occupying the space to activate.

Dimmers with infrared/ultrasonic sensors minimize false activation by detecting changes in heat sources and motion. They can be set so that only one or both detection methods are required to activate and hold lights on.

Power Controllers—For light controls with DC input voltage, you'll need a power controller to switch a 120V or 277V AC lighting circuit. Power controllers have a relay that switches a maximum 20-amp load.

Fine-tune motion-sensing light controls from your smartphone or tablet. Mounting on the ceiling gives these light controls a clearer view of the room than wall-mount sensors, so they detect motion over a larger area. They connect to a free downloadable app using Bluetooth. Use the app to adjust the amount of time lights stay on after people leave, set schedules, or override the sensor so lights are always on. Also known as occupancy sensors, they turn lights on when they sense movement and off after people leave.

Controls with infrared sensors detect changes in heat sources and need a direct view of people.

Controls with infrared/ultrasonic sensors have two detection methods to minimize false activation: infrared to sense heat sources and ultrasonic to sense motion. Use the app to adjust whether both or just one of these triggers will switch the lights.
