Lutron Adds Two New Architectural Downlights to Innovative Lighting Portfolio

Lutron Electronics Co., Inc.
The lighting brand is revolutionizing the way light can be used in the home with two sleek, smaller-than-ever downlights from its intelligent lighting portfolio

Coopersburg, PA, May 16, 2024 - Lutron Electronics, the trusted leader in architectural lighting, window shades, and intuitive controls, debuts its all-new innovation in luxury downlighting, the Ketra D2 and Rania D2 architectural downlights. D2 ushers in an exciting new chapter: making Ketra —the world’s most advanced light source— and Rania —exceptional white light technology— available in a smaller form factor than ever - a new 2” aperture downlight.

Lutron has long sought to harmoniously bring the outdoors inside, blending natural and electric light seamlessly while accentuating the beauty of the interior, from fabric colors and textures to art, and even the skin tones and features of those enjoying the space. With the launch of Ketra D2, users can now experience the characteristic elements of Lutron with dynamic lighting that adapts to various moments throughout the day and sets the desired ambiance, in the form of the brand’s smallest and most flexible downlight offering to-date. With both new downlights, people will experience high quality of light in any space in the home.

“Quality of light means more than just measuring color rendering index (CRI) or dimming capabilities,” said Ben Bard, VP of Luxury Residential Business at Lutron. “It’s about a light source’s ability to perfectly replicate natural light across a wide spectrum and then maintain that exact light output over its lifetime. Ketra uniquely delivers this quality of light and it’s now available in a 2” aperture. Additionally, Rania’s unique light engine sets a new bar for white light in the industry.”

Lutron’s luxury lighting portfolio is anchored on elevating the experience and quality of light in the home. Ketra and Rania light sources work seamlessly with Lutron’s premium lighting controls and shades to create personalized spaces. Both fixtures are also wirelessly controlled, saving time and money, and reducing the space needed for panels. As the market continues to shift towards “quiet ceilings” featuring increasingly discreet recessed fixtures and a desire for consistently reliable lighting performance, the D2 represents one of the most versatile and advanced architectural lighting solutions to-date.

Ketra D2 delivers unparalleled quality of light and unique experiences for homeowners. Some of the key features of the Ketra D2 include:

  • A “barely-there” 2” aperture, representing many engineering breakthroughs to deliver the same light quality in a smaller form factor
  • An emphasis on architectural aesthetics with a variety of trims and colors
  • Ultra-slim housings ideal for maximizing ceiling heights
  • Elevated level of precision through detailed manufacturing and an intuitive hot aiming system
  • Greater flexibility allowing increased design freedom and installation options
  • Wireless communication platform saves time and lowers cost while allowing for easy adaptation to home design changes

Rania replicates natural white light more faithfully than any other light source – second only to Ketra. Some of the key features of the Rania D2 include:

  • Breakthrough three-channel emitter produces exceptional white light
  • Broad range of white light from incandescent warmth to midday sun—all in a single light engine
  • Exact same slim housings, architectural trims, refined hot aiming system, and wireless communication as the Ketra D2
Taken together, these products open new possibilities for builders, designers, and custom home integrators who deliver innovative lighting experiences to homeowners and transform residential spaces with the highest quality of light.
