Types of Lutron Lighting Controls
Many people still think of lighting control as a simple basic switch—enter the room, flip it on; leave, flip it off. But today, lighting control has evolved. It’s about creating comfort, enhancing security, and blending into the aesthetics of your space. With Homeva and Lutron, you can go beyond the switch to control intensity, color, and timing.
Other benefits include:
- Customizable lighting scenes for diverse moods and occasions
- Enhanced energy conservation through smart scheduling and dimming
- Seamless integration with other smart home devices for total control
This comprehensive guide will dive into the different types of lighting controls we use and where they best fit into your home design.
Homeva Team Tip: Lighting control should be considered very early in a project. Doing so will increase the functionality of a space, expand design choices, and create harmony between the home and its features.
Basic Switches
Basic switches are the straightforward option for rooms that need “on” or “off” light control. More complex switches can be programmed to be controlled manually or automatically. Basic switches can be wired or battery-powered and can be mounted anywhere. With styles like toggles, push buttons, and rockers (such as Lutron’s sleek Sunnata switch), they work well in closets, garages, and workspaces. They don’t offer dimming or the customization that other controls do, but sometimes full light is all you need—especially in areas where function is more important than ambiance.
Dimmer Switches
Lutron has a long history of light control. They literally invented the first residential dimmer! With such a rich history of innovation behind them, these devices are developed to provide smooth and flicker-free dimming with an elegant design that enhances the home’s interior decor while offering a comfortable, functional environment.
Like basic switches, dimmer switches deliver on-and-off control but add the ability to adjust light intensity to create different atmospheres. Imagine, in the evening, you are ready to unwind from the day and relax. You set the mood by dimming the dining room lights and enjoy dinner with your favorite glass of wine. Afterward, you need increased light intensity for the post-dinner cleanup. Dimmer switches allow you to go from “cozy dinner” to “clean-up time” with a touch of a slider. Depending on your fixtures, systems utilize different protocols such as DALI, 0-10V and phase dimming to ensure smooth, flicker-free performance.
Dimmers can also be stand-alone to function as a standard local control, or they can function as part of a wireless system, such as HomeWorks, to allow for simple, whole-home or room control.
For those accustomed to traditional lighting controls, dimmers are a convenient, simple option that provides a dramatically improved lighting experience. Dimming also saves energy, making it a smart option for any space.
Homeva Team Tip: For the best dimming performance, it’s important that the dimmer is compatible with the light fixture it’s meant to control. Tight compatibility will ensure flicker-free light, even at .1% intensity.
Occupancy Motion Sensors and Timers
Sensors align lighting and functionality in a space. Occupancy and motion sensors send signals to turn on lighting when they detect movement or infrared radiation. They can turn lights on when movement is detected and off when a space is empty, making them ideal for high-traffic areas where physical switches are more likely to be out of reach, like hallways, garages, or outdoor spaces.
Sensors can also be programmed to adjust lighting levels in response to daylight throughout the day for optimal comfort and efficiency. For example, cooler, more energizing light in the afternoon and warm, dim light in the evening.
Using sensors and timers to turn off and on lights is a hands-free way to add convenience. These are excellent solutions for stairways, late-night trips to the bathroom or kitchen, and early risers starting their morning routine before the sun.
Homeva Team Tip: For luxury homes, we recommend integrating timers into the control system that can automatically adjust according to the time of year or your family’s changing habits. We can set schedules for personalized lighting scenes, seasonal changes, and events like vacations where you need to simulate presence.
Keypads
Keypads maximize versatility and provide full functionality in a smaller, more intuitive space than the typical bank of switches or dimmers. They not only reduce the number of switches needed but also provide precise control over brightness and can control a wide range of functions. They are also available as both wired and wireless.
Keypad control functions include:
-
Tuning lights
-
Adjusting thermostats
-
Playing music
-
Setting an alarm system
-
Controlling multiple zones
By grouping zones, we can program lighting scenes that add ease in enhancing the ambiance and functionality of a space. Scenes can be made up of multiple zones and multiple light intensities, enabling you to issue different commands to lights across zones. Imagine an “Entertain” scene in a living or dining room that dims ambient and task lighting, adjusts the accent lights around your artwork to a vibrant glow, raises automated Lutron motorized shades, and turns on music. All with just the touch of a button!
Furthermore, keypads are part of the small design details people notice. Lutron offers a handcrafted collection of elegant finishes and colors to complement any design in materials, including metal, graphite, and glass. They are custom engraved to improve ease of use and deliver ultimate personalization.

Lighting Control Architectures: Localized, Centralized, Hybrid
Networked lighting control systems are made of luminaires and control devices that send and receive data. This data makes the system more efficient. It includes performance data, critical health data, and occupancy sensor sharing. When applicable, this data helps with system learning and transmits information about whether a room is occupied to HVACs and security systems.
There are main architectural approaches to consider when comparing centralized vs decentralized lighting control. Let’s explore how localized, centralized, and hybrid systems function.
Localized
In a localized system, each lighting zone has its own switch or dimmer. Localized lighting controls allow you to dim and switch loads without requiring communication with the processor. This creates a failsafe operation of all lights. These systems are the simplest to use and are ideal for those who want to add a control system at any time, with or without prewiring. Keypads are a great way to simplify the control of multiple lights in a localized network, especially in highly trafficked locations.
Centralized
Centralized lighting control systems use keypads rather than traditional dimmers or switches in each room. Lights dim using power modules installed in remote panels, typically in a utility closet or equipment room. Electrical wiring for all lighting must route through these panels before running to the lights.
Hybrid
A hybrid designed system combines all of the above, using each where it is best suited. Keypads powered by remote panels control the lights. Typically, we advise placing these strategically to minimize wall clutter in areas where control and design aesthetics are important, such as high-traffic areas and primary bedrooms. We can install local lighting controls where simpler, more familiar controls are preferred, like guest rooms, bathrooms, or laundry rooms. Hybrid design is an excellent choice for those who want to expand their system later.
