Light Dimmers


Rotary Actuator	Toggle Switch Actuator with Mini Slide Dimmer	Rocker Switch Actuator with Slide Dimmer	Rocker Switch Actuator with Mini Slide Dimmer	Push Button Actuator with Slide Dimmer

Adjust the brightness of lights.

Toggle Switch Actuator with Mini Slide Dimmer, Rocker Switch Actuator with Slide Dimmer, Rocker Switch Actuator with Mini Slide Dimmer, and Push Button Actuator with Slide Dimmer—Slide dimmers include both a switch and a dimmer. Use them to turn lights on and off while maintaining your desired brightness level.

LED—Dimmers for LEDs only use the 0-10V dimming standard—pair them with 0-10V DC dimmable bulbs.

3-Way Switch—Three-way dimmers let you control the same circuit of lights from two locations, so they’re often used in large, open workspaces. Pair them with a 3-way on/off switch.

Smart Light Dimmers

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.

Panel-Mount Light Dimmers

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.

Light Dimmers with On/Off Switch—Dimmers with an on/off switch control power and brightness in one. Quickly tap them to turn the light on or off. When you turn it on, it returns to the last brightness level you set.

Wall-Mount Motion-Sensing Light Controls

Also known as occupancy sensors, these controls turn lights on when movement is detected and off when an area is empty. They fit standard wall plates. All have a manual time delay that will turn lights off after a set amount of inactivity.

Controls with infrared sensors detect changes in heat and require a direct view of the occupants. Controls with infrared/ultrasonic sensors detect changes in heat as well as motion to minimize false activations. You can set them to use one or both detection methods to activate and keep lights on.

Smart Wall-Mount Motion-Sensing Light Dimmers

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.

Wireless Networked Light Controls

Create a network to sync your lights—no complex wiring, central gateway, or Wi-Fi needed. These controls let you turn lights on and off or dim them in unison from a secure Bluetooth network. Build a system of up to 100 controllers—when any two are placed within 100 ft. of each other, they’ll form a network. Hardwire them to any fixture with a 0-10V dimming circuit. Use a free app to program when lights turn on or off and how they respond to sensors.

Controllers

Controllers manage a group of lights on the same circuit.

Controllers either run based on the schedule you set or receive a signal from a neighboring controller with a motion and light sensor. Make sure your group of lights doesn’t draw more than the wattage of the controller. All controllers connect to a knockout on the light or outlet box.

Controllers with Motion and Light Sensor


For 10 ft. Maximum Ceiling Height	For 30 ft. Maximum Ceiling Height

Controllers with a motion and light sensor turn lights on when people are present or dim them when there’s enough sunlight to illuminate your space.

In addition to motion and light activation, you can set a schedule and configure these controllers to trigger lights connected to other controllers on the network.

For 10 ft. Maximum Ceiling Height—Controllers for 10' ceilings are ideal for offices and other low-ceiling workspaces. They come in two pieces, and the sensor clamps into a hole cut in your drop ceiling near the controller.

For 30 ft. Maximum Ceiling Height—Controllers for 30' ceilings are ideal for high bay lighting.

Smart Ceiling-Mount Motion-Sensing Light Controls

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.

Fixture-Mount Motion-Sensing Light Controls

Detect motion near your light fixture to turn lights on and off. Compared to switch-mount motion controls that detect from a single wall, these controls have a better view of the entire space since they sense motion from above. Also known as occupancy sensors, these controls have an infrared sensor that activates when it detects a change in heat. To work properly, they need an unobstructed view of your space. All have a time delay to turn lights off after a set time. Rated IP65, these controls are protected from washdowns.

These light controls monitor motion in a full circle for coverage in all directions.

Half-circle sensing lenses are best for concentrating coverage to a certain part of a room, such as a workstation or an entrance.

Narrow sensing lenses are best for the end of aisles in spaces with high ceilings like those in warehouses and factories.

7,690 ft² Area Coverage—Those that cover 7,690 sq. ft. have lenses that can be swapped out to limit where they sense.
