It is an architectural lighting solution that compliments the ceiling and entire space while providing comfortable general illumination. Sleek and simple, thin lines of light integrate with architecture for maximum impact and design flexibility. It offers grid mount which can fit easily in a variety of T-Grid ceiling types, allowing to be fully and seamlessly integrated into 9/16" flat, 9/16" slot or 15/16" flat T-grid ceiling types. It supports to be installed in individual or seamless. Also, it is perfect for high-end drywall applications requiring a small profile with seamless lines of light and no pixels or shadows.
Purpose-Built for Designers and Electrical Contractors
The ZETA 2.3" by OKT Lighting is a premium recessed linear light engineered for commercial interior projects demanding clean visual lines and functional efficiency. Its 2.3" aperture supports a modern architectural aesthetic, while continuous row mounting and various mounting trims offer versatility for designers. Created for lighting specifiers, architects, and electrical contractors, the system streamlines installation while maintaining ceiling integrity and lighting uniformity across open spaces.
Configurable Performance with Field-Selectable Output
The ZETA 2.3" incorporates field-selectable wattage and color temperature within a single housing, offering 3 power settings (20W/25W/30W) and 3 CCTs (3000K/3500K/4000K). The 4ft model delivers up to 3,750 lumens at 125 lm/W, while the 8ft version reaches up to 7,500 lumens. A frosted PMMA lens ensures uniform light distribution without yellowing over time. This recessed linear LED light is available in 4ft and 8ft lengths and supports 0–10V dimming, optional emergency backup, and motion sensors.
Seamless Integration into Grid and Drywall Ceilings

The ceiling recessed linear light system supports continuous runs for long corridors or open spaces, offering visual consistency and reduced glare. Its architectural appeal and integrated controls make it a robust solution for high-performance commercial interiors such as offices, conference centers, and institutional buildings.
Product Advantages
Modular Mounting Options Across Ceiling Types
The ZETA 2.3" accommodates multiple ceiling interfaces through a range of mounting trims. Contractors can choose between grid ceiling kits for standard installations or trimless and flange kits for drywall ceilings, allowing the fixture to adapt to the space’s architectural intent. This modularity simplifies specification and streamlines coordination across ceiling systems commonly used by LED light suppliers in design-driven projects.
Field Flexibility Reduces SKU Load and Enhances Efficiency
With built-in dip switches for power and CCT adjustment, this recessed linear lighting solution minimizes stocking complexity while enhancing on-site adaptability. One product can fulfill various brightness and color requirements, reducing lead times and overstock scenarios for distributors and contractors. The high efficacy output—up to 125 lm/W—ensures energy performance standards are consistently met.
Visual Uniformity with Integrated Lens Technology
The high-transmission PMMA lens guarantees even illumination without visible hotspots or color shifting. Whether installed in standalone mode or continuous rows, the fixture delivers balanced brightness throughout its length. Combined with its slim aperture, this gives the ZETA 2.3" a refined appearance ideal for corporate and institutional interiors requiring modern recessed linear LED light performance with no compromise on optical comfort.
