Light ‘22, London, ENG.—Nov 22, 2022—Luminii, a Chicago-based manufacturer of industry-leading specification-grade architectural LED lighting systems, today announced the immediate availability of the company’s STENOS micro-optic platform to the European market. Complimenting the Precision Lighting (now Precision by Luminii) commercial-grade product range, the ready-to-order, field configurable micro LED product family is available in both track and downlight options, encouraging lighting designers and architectural professionals to create unique and sophisticated lighting installations across a broad range of applications.

The name STENÓS has ancient Greek origins and means narrow, tight, or close which was the brand inspiration behind the company’s segway into the micro-optic lighting market. At the heart of the STENOS system is Luminii’s proprietary, ultramodern micro-optic CSP engine, a Titanium Dioxide Coated Chip Scale Package (CSP) LED. Unique to the market, this product design approach allowed the company to create a one-of-a-kind and extremely narrow 15° TIR native beam which is the basis for all products in the STENOS portfolio. With a die size of only 1.7mm x 1.7mm, the STENOS CSP more efficiently extracts and transfers lumens directly because each CSP is only one die vs. die clusters, pushing more light forward and reducing color-over angle (COA) concerns.

“We knew we needed to bring together a world-class engineering team to develop our micro-optics products and systems,” said Jeff Parker, CEO of Luminii. “Collaboration between our US and London teams and investing in research and development at all levels of the process gave us the expertise needed to create a product design that’s quite unique from the LED to the industrial design spanning multiple patents. Moreover, our optics are the most advanced in the industry with more output and efficiency than anything available on the market today.”


The STENOS architecturally designed downlight portfolio is uniquely small, consisting of four (25mm, 75mm, 125mm, 300mm) discreet micro-downlight profiles, available in both trimmed and trimless options. STENOS downlights produce an output range of 250-1260 lumens, 4 CCTs, and 95+ CRI. The 75mm, 125mm, 300mm linear profiles offer a +/- 30º aimable tilt, glare control louvers for 15°, 30°, and 60° beams, and all downlight options feature perfect beam quality and beam shaping accessories for easy, real-time beam adjustments with simple magnetic optical attachments. All STENOS downlights are field configurable, featuring a constant voltage design that enables multiple fixtures to operate from a single power supply, resulting in a simplified installation and overall cost savings. 


Sharing many of the same attributes as the STENOS downlight product range, the STENOS micro-track profiles are available in recessed, surface, and suspended options. STENOS track features an immaculate circular beam quality from a one-of-a-kind micro-optic form factor. All STENOS ambient and directional micro-optic modules secure flush in the track system creating a seamless architectural effect and delivering up to 1260 lumens per module. The modules feature endless flexibility and can be added, removed, and repositioned with ease using simple tools even after installation. Additionally, STENOS Track is field cuttable and features an array of easy-to-install joiners while its two-circuit track enables a straightforward set-up of two separately controllable zones. Simply remove, rotate, and re-insert the module to change the circuit.


Beam shaping accessories support both the Downlight and Track Directional Modules. Customers now have the freedom to customize their lighting designs with supporting STENOS Easy SnapTM accessories and glare control louvers for 15°, 30°, 60° beams, as well as a wall wash option, all interchangeable and easily adjustable even after installation.

“Entering the micro-optic LED market is a game changer for the company in terms of what we can now offer lighting designers and architects both in the North American and European markets,” said Amy Bonder, Chief Commercial Officer for Luminii. “Today, our customers are looking for solutions that are small, flexible, and adaptable in the field. We know clients change their minds, and environments naturally change over time, and STENOS allows us to quickly adapt all while future-proofing spaces without question.”  

STENOS Downlights and Track Systems will be generally available starting in Q1, 2023 in a variety of sizes, light outputs, and CCTs. Standard finishes include black and white painted hardware. Customers may view the new STENOS collection on the Precision by Luminii website: and obtain inventory details and further guidance by contacting their local sales representatives or emailing 

So, what’s next for STENOS? Stay in the know to see what’s next in this space including a 2”(50mm) fully adjustable downlight, wall wash accessory for the 1”(25mm) downlights, track heads and cylinder options for the track system.
