Concept
Expanding the Boundaries
of Light's Beauty
for the Future
In recent years, as the search for harmony between architecture and the environment intensifies, we aim to support designers pure desire for light.

Faced with the challenge of power consumption constraints, rather than abandoning the expression of light they envision, we transform these limitations into opportunities for new forms of beauty.

KIWA's goal is to translate designers' delicate visions into reality, pushing the boundaries of space to unlock infinite possibilities in design.
Feature
The fusion of technology and aesthetics liberates the
constraints of indirect lighting.
Uncompromising light starting from 1.8W/m.
Delivers ideal gradients for projects previously limited by energy regulations. Achieving an outstanding 1.8W/m, it allows high-quality indirect lighting while meeting the strictest global environmental standards.
Precise 17×18.5mm ultra-compact cross-section.
Minimalist 17x18.5mm profile fits into the tightest architectural details. It enables installation in narrow gaps where traditional fixtures cannot reach, illuminating the space while remaining unobtrusive.
Versatile choices from 25° to diffuse.
Offers controlled beams at 25°, 40°, 60°, and soft diffusion. These diverse options, including asymmetric distribution, empower designers to realize their exact vision within a single series.
Seamless gradient from 0mm distance.
Proprietary optics ensure a smooth rise of light without dark scallops. Even when placed flush against walls, it produces a flawless gradient that adds profound depth and emotion to spaces.
Powerful output up to 3,800lm/m.
Achieves high output up to 3,800lm/m while remaining ultra-compact. Ideal for large spaces and high ceilings, it delivers the necessary throw and intensity to transform grand architectural environments.
OptiFlow Array TM for ultimate precision.
Equipped with our proprietary Linear Lens Array to maximize efficiency. It eliminates yellow rings and multiple shadows, delivering the pure, high-precision light required by professional lighting designers.

Product Story
Silent Power.
Infinite Design.
Harmonizing environmental consciousness with uncompromising luminosity.
Inspired by the Japanese concept of "Kiwa"—the edge or boundary—and driven by a mastery of light, KIWA is a next-generation indirect lighting brand.

We empower lighting designers to unlock their creativity and craft new narratives within architectural spaces.
Our unwavering commitment is to the pure beauty of light, with no compromises.
The Genesis: Never Give Up on Beautiful Light
In an era marked by increasingly stringent environmental regulations and limited power allocations for lighting, the rich spatial expression once offered by indirect illumination is facing challenges.

KIWA was born from a resolute conviction: "We will not let you abandon the beauty of light." Our brand’s origin lies in overcoming the paradox of maintaining ideal lighting effects while operating at extremely low power consumption.
The Philosophy: Japanese Sensibility and the Essence of "Kiwa"
The name, KIWA, is derived from the Japanese word for "edge" or "boundary." We believe that the subtle details—the "edges" of a space—are where a calm yet powerful beauty resides. KIWA also embodies the spirit of Kiwameru (to master or push to the limit), harmonizing a designer's vision with technical feasibility. Much like the essence of Zen or Omotenashi (hospitality), our fixtures are unobtrusive; instead, they quietly yet dramatically elevate the value of the environment.
Optical Innovation: OptiFlow Array™
At the heart of KIWA lies our proprietary optical technology, OptiFlow Array™. This sophisticated system ensures high-efficiency light transport—delivering every lumen from the source to the external space—paired with nano-lenses that control light at a sub-microscopic scale to produce the most exquisite distribution.

By thoroughly eliminating scallops and yellow rings, we have achieved an unparalleled, seamless gradation that rises smoothly from the mounting surface. Even with fixed distribution, we promise a "silent and strong light" that remains flawless regardless of architectural conditions.
