The 3.5" x 3.5" Square Trimless LED Downlight is a versatile, high-performance recessed fixture designed to deliver seamless integration and superior illumination across a wide range of applications. Its trimless design offers a true mud-in option for drywall installations, ensuring a clean, architectural finish with no visible fasteners. With a shallow 2.6" housing, this downlight is ideally suited for spaces with restricted plenum depths, while its precision-engineered components deliver excellent thermal management, optical control, and lighting quality.
At the heart of the fixture is a proprietary LED array that delivers lumen outputs ranging from 700 to 2100, making it suitable for everything from intimate residential spaces to high-ceiling commercial environments. The fixture supports 80, 90, and 97 CRI options, providing specifiers with a full range of color rendering performance for both general illumination and high-fidelity applications where color accuracy is critical. Standard color temperatures include 2700K, 3000K, 3500K, and 4000K, while advanced Warm Dim options recreate the natural black body curves of halogen and incandescent sources by dimming smoothly down to 1800K. Tunable White configurations extend the flexibility further, offering three ranges—Comfort (1800K–4000K), Preference (2700K–5000K), and Activity (2700K–6500K)—to support circadian lighting strategies, occupant well-being, and dynamic architectural design.
Optical performance is enhanced by a selection of beam spreads ranging from 25° to 90°, enabling use in accent, task, and general lighting scenarios. Reflector trims are available with 50°, 60°, or 75° cut-offs, balancing visual comfort with shallow plenum requirements. Solite lens options add further versatility, offering glare-free illumination with beam spreads of 70° or 90°. The die-cast aluminum reflector ensures smooth, uniform light distribution, while torsion springs secure the trim tightly to the ceiling plane. Finishes include Clear Diffuse, Warm Diffuse, White, and Black, as well as The Naturals—a collection of biophilic-inspired finishes crafted from low VOC vinyl to complement modern interior aesthetics.
The downlight is available with multiple control and driver options, including 0–10V (down to <1%), DALI, Lutron Hi-Lume EcoSystem, forward phase dimming, and PoE (Power over Ethernet) compatibility for advanced digital lighting infrastructures. Emergency configurations provide 7W for 90 minutes, with maximum mounting heights up to 22.5 ft for Clear Diffuse and White trims and 15.3 ft for Black and Warm Diffuse trims. Electrical design features include constant current dimming drivers, power factor greater than 0.9, and thermally protected housing options. IC-rated and airtight housings allow for direct contact with insulation, while non-IC and wood ceiling housings provide additional versatility for specialized construction needs.
Built with durability and installer convenience in mind, the fixture incorporates a die-cast heat sink for maximum thermal dissipation, a die-formed aluminum housing with integral junction box, and multiple ½" pry-outs for wiring flexibility. Ceiling thickness accommodation ranges from 0.5" standard to 1.5" with field adjustments, and the fixture remains under 5 lb for lightweight installation. Butterfly brackets allow EMT mounting, while optional bar hangers support a variety of ceiling conditions. Factory options include Chicago Plenum, outdoor-rated construction for recessed exterior ceilings, and airtight trims that maintain restrictive airflow in compliance with ASTM-E283.
Certified to UL and cUL standards, this downlight is rated for dry, damp, and wet locations with indoor use standard and optional outdoor configurations available. With its combination of high lumen outputs, precise optics, multiple control systems, and architectural finishes, the 3.5" x 3.5" Square Trimless LED Downlight delivers unmatched flexibility for residential, retail, hospitality, and commercial projects where seamless design and uncompromising light quality are paramount.
