Lumileds joins Legrand partnership to speed adoption of tunable white LED lighting

Legrand, North & Central America (a specialist in electrical and digital building infrastructures) and LED maker Lumileds LLC of San Jose, CA, USA have partnered to bring to market a simple-to-integrate and easy-to-install plug-and-play solution that delivers high-quality tunable white light.

Through its Matrix Platform, Lumileds will provide intelligent light sources (based on its LUXEON LEDs) that are uniquely characterized and programmed to work with Legrand’s Wattstopper blanco tunable-white logic modules within the Wattstopper Digital Lighting Management (DLM) lighting controls solution. Lumileds joins existing Legrand partnerships in tunable-white light engine as the exclusive LED array provider.

“The lighting industry is beginning the transition from providing only static white light to enabling dynamic end-user-selectable color temperature solutions as a subset of what is becoming possible with intelligent and human-centric lighting fixtures and controls,” says Steve Barlow, senior VP/general manager of Lumileds’ Illumination Business. “Our joint commitment is to optimize the customer experience by offering perfect fixture-to-fixture color matching over a wide correlated color temperature (CCT) range through simple, seamless integration of light sources into fixtures that interface with Wattstopper tunable white modules and their lighting controls,” he adds.

The partnership - combining expertise in LED light sources, drivers and controls, along with the blanco intellectual property from Lumenetix Inc (which offers tunable light sources for commercial, residential and professional film/studio lighting applications) - ensures the development of market-ready solutions for a range of tunable white applications across commercial, healthcare, hospitality and education market segments.

Legrand’s Wattstopper Blanco 2 is a two-channel LED light engine providing high-quality light with a tunable range of 3000-5000K. With a tunable range of 2700-6500K, Blanco 3 is a three-channel LED light engine that adjusts correlated color temperatures precisely along the blackbody locus to replicate natural daylight.

Blanco logic modules connect to dedicated LED arrays developed by Lumileds LUXEON LED-based Matrix Platform. The arrays are available in a wide range of Zhaga-compliant linear or custom form factors to meet the requirements of lighting fixture manufacturers. Both Blanco light engines provide white light with a color rendering index (CRI) and TM-30 fidelity index of at least 90. Both also provide flicker-free dimming from 100% to 0.1%.

“Legrand’s collaboration with partners like Lumileds, as a leader in the LED industry, is essential in the adoption of dynamic lighting control,” says Andrew Wale, VP product marketing at Legrand. “As high-performance buildings shift their focus towards a total building performance model, occupant comfort and productivity become paramount,” he adds. “Tunable lighting, as part of this shift and a dynamic lighting control strategy, plays a key role. But its potential is only realized when quality of light can be delivered from an end-to-end solution that integrates lighting source, fixture and controls with ease of system design, install, commissioning and first use.”
