LED Lighting and Controls Guide

A Guide to LED Lighting Controls

Just like we tailor our coffee orders and curate our Spotify playlists, we want our lighting to suit our exact preferences. This demand for personalization is driving innovation in commercial LED lighting controls, offering eco-friendly options and precise control over lighting hue and temperature.

Sophisticated smart technology has replaced simple wall switches and dimmers. This new generation of LED lighting controls empowers users to save energy, comply with regulations, and meet various needs with just the push of a button. But what happens after you push that button? It depends on the method used in the specific control. Let's explore the most common methods, how they work, and how they might be used.

Different Methods of LED Lighting Controls

Commercial LED lighting controls ensure that lighting is not just a passive element of our workplaces and institutions but an active participant in our daily comfort, safety, and productivity. These systems range from motion-detecting sensors to smart, network-connected setups controllable via smartphone.

Here’s an overview of the different methods of LED lighting controls and what to consider as you incorporate them into your commercial lighting projects.

Microwave Detection

Using radio signals, microwave sensors detect movement by bouncing signals off objects to determine direction and speed. This technology is especially effective with daylight harvesting, adjusting indoor lighting based on available natural light, ensuring optimal lighting conditions and energy savings.

Use Case: In a busy office with an open-floor layout, microwave detection can dynamically adjust lighting as employees move throughout different areas.

Considerations: Calibrate sensors to avoid false triggers caused by minor movements and integrate them with daylight harvesting systems for maximum energy efficiency.

Bluetooth Control

Passive Infrared (PIR) Sensors

These sensors detect motion by sensing the heat signatures of moving objects. Some systems combine microwave and PIR technologies to enhance detection capabilities, such as in restrooms where occupants may not be directly visible.

Use Case: An open-plan office might use PIR sensors to manage lighting based on occupancy, saving energy by activating lights only when employees are present.


  • Placement and Line of Sight: Ensure sensors have a clear view of busy areas without obstructions.
  • Sensitivity Settings: Adjust sensitivity to match expected occupancy and activity levels.
  • Field of Coverage: Ensure the sensors’ coverage area corresponds with the office layout to avoid blind spots.
  • Integration: Confirm compatibility with existing lighting infrastructure and broader building systems.
  • Avoiding False Triggers: Install sensors away from heat sources like HVAC vents.
  • Activity Levels: Ensure sensors are responsive to typical office activities.
  • Shortcomings: Be aware of potential failures, as sensors aren’t infallible.

Bluetooth technology allows lighting control via an app, with each fixture forming part of a mesh network for seamless communication across buildings or campuses. This method enables a range of controls, from dimming to switching, all from a smartphone or tablet.

Use Case: An art gallery might use Bluetooth control to adjust lighting intensity and color to match different exhibits directly from a mobile device.

Considerations: Ensure the mesh network is robust enough to handle multiple fixtures, and implement security measures to prevent unauthorized access.

DMX (Digital Multiplex)

Commonly used in theatrical and entertainment settings, DMX protocol is designed for controlling complex lighting arrangements and effects. Its robust control capabilities make it ideal for creating dramatic lighting scenes.

Use Case: A theater group might use DMX controls to manage complex lighting arrangements for productions, creating dynamic scenes that change with different acts.

Considerations: The control system should be user-friendly for technical staff, with backup options to prevent show disruptions.

0-10V Dimming

Widely used for dimming lights, 0-10V dimming allows users to adjust brightness through a simple voltage scale, compatible with many commercial lighting systems.

Use Case: A corporate conference room might use 0-10V dimming to adjust lighting levels for different meeting types, from bright light for video conferences to dimmed lighting for presentations.

Considerations: Ensure the system is compatible with existing lighting fixtures and allows for smooth transitions between light levels without flickering.

Pulse Width Modulation (PWM)

PWM dimming controls the brightness of LED lights by rapidly turning them on and off at high frequencies, providing precise control without impacting the LEDs' lifespan.

Use Case: An electronics manufacturing facility might use PWM to control LED brightness, ensuring optimal illumination for detailed assembly work.

Considerations: Set the PWM frequency to avoid flickering perceived by the human eye and ensure it doesn’t interfere with sensitive electronic equipment.

Building the Perfect LED Lighting System

LED lighting controls exemplify how the demand for customization drives technology forward. Smart tech now allows users to adjust their lighting easily through user-friendly interfaces.To get the most out of these systems, set them up correctly and consider specific factors to avoid issues like false alarms and inefficiencies. As technology advances, these lighting systems will become even smarter and more user-friendly, making them an integral part of our daily environments.
