New from Acuity Brands is the Modulus low voltage distributed power and control system.

The Modulus, released on Dec. 9, provides digital control and network technologies for LED luminaires. It also provides the same capabilities as Acuity Brands’ control and driver systems, such as flicker-free dimming, networked lighting controls and embedded sensors, emergency battery back-up and tunable white.

The Modulus system uses a single unit to power a luminaire run of up to 32 feet (9.75 metres). This configuration provides flexible lighting design, allowing the Modulus technology to be embedded in a multitude of new luminaire form factors.

“There’s a market need for ever smaller, unobtrusive luminaires used for creating expansive designs in spaces. However, these small luminaire form factors make it difficult to embed existing technology due to spatial constraints,” said Gilles Abrahamse, VP of Acuity Brands Lighting, Digital Luminaire Components, in a release. “It provides power and control for luminaires as small as one inch in depth. We were able to create Modulus by leveraging Acuity Brands’ expertise in developing drivers, sensors and controls.”


Modulus will support Acuity Brands’ efforts to elevate luminaire design. It utilizes an eldoLED driver, an IOTA power pack for emergency back-up power and nLight firmware. Modulus also supports controls systems with open protocols.

The Modulus low voltage distributed power and control system will be initially available within the Renna luminaire family from Peerless. The system can be integrated or unified with additional  technologies from Acuity Brands, such as Atrius IoT systems, to provide indoor location services used for wayfinding, asset tracking and other building and business applications.
