We had the pleasure of joining two leading design firm executives for an in-depth, behind-the-scenes look at the science and manufacturing of LED lighting at Ketra headquarters.
Huge thanks to the team at Lutron Electronics for their incredible hospitality—seeing their innovation and precision up close was nothing short of inspiring! 💡✨

The two buildings at 169 and 181 Henry Street have lived many lives—from ice cream production and scientific glassware manufacturing, to warehouse and shipping. Today, they form NXTHVN: a 40,000SF hub for artist studios, exhibitions, coworking spaces and community programming.

The lighting approach was to support this transformation without erasing the past. Suspended linear fixtures reference the fluorescent tubes once used in the buildings’ industrial years—but are now energy-efficient LEDs, delivering soft, even ambient light suited for creative work. The industrial language remains, while the experience is entirely redefined. In the exhibition spaces, a flexible track lighting system allows for a wide range of artwork and curatorial setups.

What do all dental patients stare at? ...The ceiling!

Instead of a typical 2x2 grid ceiling, this dental office features a custom organic screen—designed by the dentist’s husband, an industrial designer—to create something engaging to look up at. Concealed uplights in the cavity above the screen wash the concrete slab, hiding ducts and infrastructure while casting the screen’s pattern as shadow against a soft glow.

The uplighting is tuned with a subtle purple hue—cool and calming, but warm enough to play nicely with the bold red dots dancing across the dividers. Below, crisp white downlights precisely illuminate sinks and workstations for clarity and function, while admin areas remain clean and neutral.

A layered approach—turning a typically overlooked surface into the focal point. ✨🦷

Rising thirty stories above Manhattan, The Dylan was designed as an intimate retreat — only six homes per floor, a sanctuary above the noise. Our lighting carries that intention through every amenity space.

It begins at the entrance, where walls grazed with soft light create a tunnel effect — drawing you in, orienting you, slowing you down before the lobby opens up. There, a skylight offers an unexpected upward view of the full height of the tower, and a 13' high floor-to-ceiling vertical cove reads like a window, further opening the enclosed space. The effect is dramatic and calm at once — a deliberate pause before the elevator zone takes you home.

The gym shifts register entirely. Brighter, more energetic illumination signals the change in purpose. The basketball court is evenly lit for performance, with fixtures encased in industrial-style boxes, protecting the lights from errant three-pointers.

Then the sky deck: warm, unhurried light for grilling and lounging, the Empire State Building presiding above.

The 70-seat space is inspired by Monterrey, Mexico—the hometown of both the chef and the owner—and features a sculptural installation behind the bar that evokes Monterrey’s mountain range. Hidden deep within each layer of wood paneling are LEDs that follow the curves of the mountains – no visible bulbs, no harsh sources – just light washing smoothly across the layers, creating depth and distance. Multiple mockups were needed to perfect the balance of shadow and glow, so it feels less like a lighting feature and more like a horizon.

The fixtures in the dining area run on a system, allowing each light to be individually tuned for warmth and color saturation. The room reads invitingly warm, but individual elements are dialed up to cut through: greenery that glows with vivid life, textures and materials catching the light in ways that feel both surprising and intentional.

Lighting plays a key role in reactivating this 1887 masonry structure at the heart of Pratt’s campus. ’s renovation highlights the historic volume while supporting a flexible, social interior for students.

Indirect uplights at the base of the exposed roof structure wash the sloped ceiling, turning it into a luminous focal plane and making the vast volume legible. Below, small-aperture, low-glare downlights provide comfortable ambient light across open gathering areas and the stepped “piazza,” and flexible lighting for daily concerts, lectures, and evening galas. A subtle grazer traces the underside of the wood trusses, bringing out texture and depth without distraction.

Layered together, the lighting balances performance and atmosphere, revealing the building’s history while creating a space that encourages interaction and chance meetings.

At the entrance, the words "Student Union" are legible as shadow by day — heavy-gauge metal letters cut away from the facade. By night, they glow from the activity within.

A space that has hosted Zadie Smith, Richard Dawkins, John Cleese, Elizabeth Gilbert, César Aira and Jeffrey Eugenides deserves more than fluorescent tubes and track lighting. But it also runs on a real-world budget — which meant every decision had to work harder.

The guiding idea for Greenlight Bookstore was large luminous volumes rather than many small point sources. A room full of competing bright spots creates visual noise — the opposite of what a browser, a reader, or an audience needs. Working closely with fredericktangarchitecture, we built a full-scale mockup of the faux skylight coves in his office — testing the quality of light before committing to the ceiling. The result is a narrow storefront that, despite limited natural light, feels warm, generous and without edge.

This prewar penthouse had a terrace on all four sides — and almost no connection to it. The original apartment was locked away from its own light and air.

The renovation by Tinmouth Chang Architect changed that. Walls came down, windows grew, and suddenly the exterior views were present from the moment you stepped off the elevator. Our lighting followed that same logic of openness and continuity. Every available cavity between the structural ceiling beams was used to integrate light coves and recessed downlights — allowing the ceiling to read as simple and uninterrupted, a calm plane above a newly open plan.

A single light cove runs the full length of the combined living and dining room, unifying the great room while reinforcing its connection to the exterior dining terrace beyond. In the master suite, the bedroom extends outward to a secret garden enclosed by vertical plantings — and cascading waterfalls of light wash down the green wall, creating a soft, soothing threshold between the interior retreat and the city below.

Lighting helps unify Mannes Conservatory within the layered, multi-level environment of Arnhold Hall in this renovation by —supporting classical music study, recording, rehearsal, and performance.

At the street edge, lighting at windows and vitrines turns the building into a visible “process lab,” connecting passersby to the creative activity inside. High CRI, high R9 LED sources are used where The New School’s signature red dominates—enriching color saturation and depth. This signature red paired with white walls and black ceilings identifies Mannes areas within the multi-program building.

In circulation spaces, suspended linear pendants form graphic compositions inspired by musical notation, acting as intuitive wayfinding elements. Their shifting density allows corridors to open up at key moments—creating informal social zones within a consistent lighting language.

Designated a NYC landmark and listed on the National Register of Historic Places, 100 Barclay's lobby renovation came with strict constraints: no penetrations to the plaster ceilings, limestone walls or floors. Every lighting decision had to be freestanding or hidden within existing infrastructure.

In Ralph Walker's original 1927 lobby, all lighting came from incandescent wall sconces that flattened the space into something undifferentiated and dim. We replaced the incandescents with LEDs and layered in new elements for depth and contrast. A new LED grazer hidden above the revolving entrance door makes the decorative gold panel glow, creating a warm visual anchor at the threshold. To address the sheer volume of the 22.5' high lobby, we added glowing elements to new partitions that divide the lobby into intimate zones, with high CRI spotlights concealed at their tops — aimed at the beautiful hand-painted ceiling frescoes, which had gone largely unnoticed in the former dim lighting. Table lamps in the seating areas complete the composition, pulling the eye downward and giving the space a human scale it never had before.

On the exterior, we lit the four corners and the crown — so that Walker's tower announces itself on the Manhattan skyline the way it always deserved to.
