Install the Controls. Not the Callbacks.
Install the Controls. Not the Callbacks.
Lighting control problems rarely appear on day one. They show up weeks later when spaces behave inconsistently, lights drift out of tune, and adjustments never stop. Missed sensing, poor control strategies, and overcomplicated systems turn a finished install into repeat visits.
Summit Electric Supply helps you choose Leviton lighting control systems designed to manage how spaces operate over time. With proven control strategies, scalable control platforms, and the right mix of sensors and devices, lighting behavior stays predictable as spaces change.

Leviton Lighting Control Benefits
Leviton Lighting Control Benefits
- Occupancy Control – Sensors respond to presence so lighting operates when spaces are in use. This strategy is implemented through select occupancy sensor and control families designed for room-level automatic on and off operation.
- Vacancy Control – Manual-on and automatic-off strategies help limit unnecessary lighting activation while ensuring lights shut off when spaces are vacant. Vacancy control is supported through designated sensor and wall control families used in code-driven applications.
- Daylight Harvesting – Photocells adjust lighting output based on available natural light to help maintain consistent levels throughout the day. This strategy is supported through select daylight sensing and system-based control platforms used in perimeter and skylit spaces.
- Dimming Control – Dimming control allows light levels to be adjusted rather than switched abruptly, supporting task tuning and occupant comfort. Dimming capability is available through designated dimmer, driver, and lighting control system families.
- Multi-Technology Sensing – Combining sensing technologies improves coverage in spaces with partitions, varied movement patterns, and obstructions. Multi - technology sensing is available in select sensor families designed to reduce nuisance shutoffs.
- Room-Based Control – Room-based control keeps lighting response tied to individual spaces rather than large shared zones. This approach is characteristic of distributed lighting control platforms and room controller families.
- Wired or Wireless – Both wired and wireless lighting control approaches are available to support new construction and retrofit conditions. Capability depends on the selected control platform and device family.
- App Configuration – Digital configuration tools allow control settings to be adjusted without rewiring. App-based configuration is supported through select wireless and system-based control platforms.
- Central Scheduling – Time-based scheduling supports coordinated lighting operation across larger areas or entire facilities. Scheduling capability is provided through relay-based systems and centralized control platforms.
- Energy Readiness – Lighting control strategies support requirements commonly associated with energy codes and utility programs. Energy readiness depends on the selected control platform and configuration.

FAQs
Frequently asked questions about Leviton Lighting Control & Energy Management.
-
What are commercial lighting controls?
Commercial lighting controls manage when lights turn on, turn off, and adjust output based on occupancy, schedules, and daylight. They are used to reduce wasted runtime and keep lighting behavior consistent across spaces.
-
How are lighting controls different from standard switches?
Lighting controls respond automatically to conditions like presence and daylight instead of relying only on manual operation. This reduces manual adjustments and supports more predictable behavior.
-
When should occupancy control be used instead of vacancy control?
Occupancy control turns lights on automatically when a space is entered. Vacancy control requires manual on and automatic off and is often used where tighter control or reduced runtime is desired.
-
Why do some lighting controls cause complaints after installation?
Complaints usually come from poor coverage, incorrect settings, or control strategies that do not match how a space is used. Selecting the right control approach upfront helps avoid this.
-
What is daylight harvesting?
Daylight harvesting adjusts electric lighting based on available natural light. It helps maintain consistent light levels and prevents over lighting in perimeter or skylit areas.
-
Are lighting controls required by energy codes?
Yes. ASHRAE 90.1 and California Title 24 require automatic shutoff, manual -on capability, and daylight response in most commercial spaces. GreenMAX® relay panels are certified Title 24 and ASHRAE 90.1 compliant. Smart Ceiling Mount Sensors (CMS) support all three control strategies in a single device.
-
Can lighting controls be added in existing buildings?
Yes. Wireless and fixture integrated control options allow controls to be added without extensive rewiring in many retrofit situations.
-
What is the difference between room based control and relay panel control?
Room based control manages lighting locally within each space. Relay panel control centralizes scheduling and large area shutoff across broader zones.
-
When should wireless lighting controls be considered?
Wireless controls are commonly used in remodels or tenant improvements where pulling new control wiring is not practical.
-
How are lighting controls adjusted after commissioning?
Many systems use mobile apps or software tools to adjust timeouts, dimming levels, and response behavior without hardware changes.
-
Do lighting controls work with LED fixtures?
Yes. Most commercial lighting controls are designed to work with LED fixtures using common dimming methods.
-
What causes lights to drift out of adjustment over time?
Changes in space use, furniture layouts, or sensor coverage can affect performance. Selecting flexible control strategies helps accommodate these changes.
-
Can lighting controls integrate with building systems?
Some lighting control platforms support integration with building management systems when required. Integration capabilities depend on the selected control platform and system architecture.
-
How do lighting controls support energy management programs?
Lighting control strategies such as scheduling, daylight response, and demand response help reduce unnecessary runtime and support energy management and utility program requirements.
