Cree Lighting, a leader in innovative LED lighting solutions, is pleased to announce an expansion in its available correlated color temperature options to include a new 1900K/50CRI (19K5) offering across a broad range of its popular outdoor lighting solutions. The 19K5 option was specifically developed to significantly reduce blue light emissions of outdoor lighting applications while still maintaining illumination and energy performance goals.

With a correlated color temperature (CCT) of 1900K and color rendering index (CRI) of 50, the 19K5 option emits a warm, amber-white light with less than 2% blue content between 400nm and 500nm. Powered by Lumileds’ LUXEON 3030 LEDs with NightScape Technology™, 19K5 delivers a new, purpose-built option for municipalities and blue-light-sensitive regions where reducing light pollution, and its impact on people, wildlife, and the night sky, is a priority.

Meeting Modern Outdoor Lighting Needs
As support for wildlife and dark-sky preservation grows, a new trend has appeared with the emergence of lighting ordinances that set strict limits on blue light emissions. Lumileds’ NightScape Technology was developed with these use cases in mind—providing a thoughtfully engineered solution that balances ecological awareness with practical lighting needs. It stands apart from typical amber or narrow-spectrum alternatives by maintaining LED efficiency alongside comparably superior CRI even at ultra-low CCT levels.

Cree Lighting is also rising to meet these new standards with solutions such as Guideway Series street lights and OSQ Series area lights, which now feature this 19K5 LED option in combination with NanoComfort® Technology, a no-compromise optical design solution that delivers precise illumination, superior visual comfort, and elevated efficiency up to 171 LPW. These parallel advancements enable an unmatched combination of color, comfort and control to support communities with their environmentally conscious lighting goals.

Key Features of the 1900K/50CRI LED Lighting Solution:

• Low Blue Light Emissions: Less than 2% between 400–500nm, supporting wildlife protection and dark-sky preservation.
• 1900K Warm Light: Casts a soft, flame-like white glow designed for nighttime environments with minimal glare or disruption.
• Targeted CRI of 50: Broad spectrum light delivers visually comfortable outdoor color rendering appropriately balancing color accuracy and critical environmental impact.
• Energy-Efficient LED Performance: Provides high luminous efficacy while delivering a specialized spectrum output.
• Environmentally Conscious Option: Meets specifications for low-impact outdoor lighting, minimizing impact on wildlife, such as migrating birds and their habitat.
• Reliability in the Field: Built to endure harsh outdoor environments, offering long-term, low-maintenance performance.

Purpose-Built Lighting for a Responsible Future
This new 1900K/50CRI choice expands Cree Lighting’s outdoor portfolio, offering a solution for those seeking to minimize the ecological footprint of their nighttime illumination. Whether in coastal regions, wildlife corridors, or designated dark-sky zones, this low-blue solution allows communities to provide safe and responsible lighting.

“19K5 provides a thoughtful, intentional choice for communities proactively seeking to reduce blue light emissions,” said Kurt Wilcox, Vice President of Research and Development, at Cree Lighting. “When combined with our popular NanoComfort Technology optical platform, this expanded offering demonstrates our commitment to lead the industry in delivering high value application-optimized solutions to our customers.”

Steve Barlow, CEO of Lumileds, added, “NightScape Technology is crafted for applications where the goal is to minimize environmental harm while delivering efficiency and a flame-like warm glow not possible with amber sources. We are proud to provide Cree Lighting with LEDs that help communities achieve their lighting goals.”
