The 4-inch square pendant mount LED cylinder brings architectural elegance and technical versatility to modern lighting design. This luminaire embodies modular adaptability, simple installation, and superior light quality, creating seamless integration into spaces of any scale—from intimate hospitality settings to expansive atriums. Its flexible configuration options empower designers to achieve customized lighting experiences while maintaining precise control over aesthetics and performance.
At the heart of this cylinder lies a commitment to light quality. The patented Bounding Ray™ optical system minimizes glare and visual fatigue while enhancing the visual comfort and architectural detail of every environment. With a 45° or 65° visual cut-off that prevents source visibility, the system maintains low-brightness apertures and soft transitions across beam edges. Its optical design produces clean, crisp beams from 10° to 60° in 5° increments, along with smooth batwing distributions that achieve uniform brightness fixture-to-fixture. All optics are field changeable for maximum on-site flexibility.
Color consistency is ensured through Perfect Color™ technology, maintaining an industry-leading 0.5-step MacAdam ellipse—far surpassing typical 3-step variations. The LED light engine delivers up to 4500 lumens with options for 80, 90, or 95 CRI, including R9 values above 80 for vivid reds. Lumen maintenance reaches 90% at 55,000 hours, sustaining color accuracy and output over years of use. The luminaire achieves 101 lumens per watt, with an L90 lifetime of 60,000 hours and IEEE flicker-free performance powered by EldoLED drivers.
Architectural flexibility extends across body lengths and finishes. The cylinder is available in 5-inch (shallow), 8-inch (standard), 12-inch (long), and 15-inch (extra-long) versions, accommodating diverse ceiling heights and spatial proportions. Trim options include cone and lensed wall wash variants, with beam angles ranging from 10° to 60° and cutoff selections of 45° or 65°. The toolless twist-and-lock system allows effortless field interchangeability for both trims and optics, while finish choices encompass 20 architectural colors, 10 reflector colors, and the full RAL palette.
Mounting versatility ensures compatibility with a variety of architectural conditions. Stem suspensions are field-cuttable and specified in 2-foot increments, supporting both indoor and outdoor use. Cord-mounted configurations integrate a hang-straight mechanism to maintain perpendicular alignment, with cords adjustable down to 4 inches and paired with aircraft cables for secure suspension. Both rigid stems and cords enable installation to standard 4-inch octagonal or square junction boxes, with optional matching conduit covers and post-installation alignment slots for precision adjustment.
A full range of electrical and control options allows seamless integration into modern building systems. The luminaire supports 120, 277, 347, and universal 120-277V inputs, with dimming protocols including 0-10V, DALI, DMX, and forward-phase (ELV). Dimming levels extend from 100% down to 0.1%, offering smooth fade-to-black transitions and stable, flicker-free control. Multiple driver configurations are available for compatibility with various control ecosystems.
Control integration is optimized through the nLight platform, available in both wired and wireless formats. nLight wired systems connect luminaires through CAT-5 cabling for centralized management, while nLight AIR enables wireless communication via CLAIRITY+ mobile app control. Both configurations support scalable network zones for single-room to campus-wide control, ensuring adaptability to different project requirements.
Emergency battery options (E7WR, E10WR, E15WR) provide code-compliant 90-minute backup operation, housed in remote sidecar enclosures. All luminaires meet NFPA 101 Life Safety Code and are compliant with California Energy Commission Title 20.
Precision construction ensures durability and serviceability. The heavy-gauge extruded aluminum housing promotes efficient thermal management through integrated airflow channels, extending the lifespan of both LEDs and drivers. Field-replaceable light engines and drivers simplify maintenance from below the ceiling plane.
The fixture meets stringent regulatory and quality standards, holding CSA, NOM, Energy Star, and UL certifications. It is available in Damp and Wet Location ratings, ensuring reliability in both interior and exterior conditions. Photometric testing is conducted under IES LM-79 and LM-80 standards, with lumen maintenance projections based on TM-21 calculations.
A broad selection of lumen outputs—from 500 to 4500 lumens—accommodates varied lighting layers, while correlated color temperatures include 2700K, 3000K, 3500K, 4000K, and 5000K options. This adaptability makes the cylinder ideal for diverse applications across education, government, healthcare, hospitality, worship, corporate, and retail environments.
Together, these characteristics define a lighting solution that balances precision optics, modular design, and intelligent control—enabling designers and facility managers to achieve aesthetic harmony, visual comfort, and technical performance in every installation.
