The EVO 4" Surgical Suite Downlight combines precision optical control, superior construction quality, and advanced integration capabilities to meet the demanding standards of healthcare and cleanroom environments. Its batwing optical distribution creates a uniform and wide-angle spread of light across both horizontal and vertical surfaces, ensuring smooth edges and consistent brightness without hot spots or rings. The optical system employs a 45° cutoff for visual comfort and precise beam shaping, available in medium, medium-wide, and wide beam options. Open, corner, and double wall wash solutions extend design flexibility, while the choice of flushed or regressed lens trims provides tailored performance and aesthetics for specific applications.
The fixture’s Bounding Ray™ optical principle produces top-down flash characteristics for optimal glare control, maintaining visual comfort and clarity even in environments requiring strict visual precision. With lumen packages ranging from 250 to 4,500 lumens, the luminaire supports diverse lighting needs—from low-intensity patient areas to bright surgical suites. Multiple optical options, reflector finishes, and field-interchangeable trims and optics allow for versatile design customization. Reflectors are available in semi-specular, matte diffuse, and specular finishes, complemented by powder coat and antimicrobial paint options that enhance safety and hygiene in medical settings. The downlight accommodates metal, wood, drywall, and suspended grid ceilings, supporting a wide range of installation conditions.
Performance reliability and serviceability define the EVO 4" Surgical Suite Downlight. The lensed LED light engine is fully serviceable and upgradeable, designed for field maintenance from above or below the ceiling. The optical system maintains complete mechanical alignment through a unitized attachment of the light engine to the lower reflector, ensuring consistency in light distribution. Rated for 70% lumen maintenance at 60,000 hours, the fixture upholds long-term performance and durability. With a UGR of zero when aimed at nadir and cutoff angles of 60° or less, the fixture minimizes discomfort glare per CIE 117-1995 standards. Tested and listed for wet location and NSF2 Splash/Non-Food Zone environments, it also meets IP64, IP65, and IP66 ratings, ensuring protection against dust and moisture ingress.
The EVO downlight integrates seamlessly with nLight® wired lighting control systems, offering digital flexibility through nTune™ and WarmDim® technologies. These dynamic lighting features enable smooth transitions between tunable white ranges and dim-to-warm scenes, replicating natural light behavior. Up to ten different driver configurations are available, including 0-10V, DALI, and DMX protocols, with eldoLED ECOdrive and SOLOdrive options ensuring precise dimming performance down to 0.1%. The drivers conform to IEEE P1789 standards for flicker-free operation, ensuring consistent visual comfort across all dimming levels. Drivers are inaudible in 24dB environments, power factor exceeds 90% at full load, and efficiency remains above 80% across input voltages. These characteristics ensure stable operation under voltage fluctuations commonly encountered in commercial and institutional facilities.
Constructed from 20-gauge galvanized steel, the luminaire housing is built to endure mechanical stress, vibration, and daily operational demands. Pre-installed telescopic mounting bars allow flexible placement, accommodating ceiling spans from 15" to 26" and ceiling thicknesses up to 1½" (extendable to 5" with optional adapters). Tool-less post-installation adjustments simplify setup, while internal components are securely supported to prevent movement or damage over time. Fixtures operate at a standard ambient temperature of 25°C, requiring half-inch clearance from non-combustible materials in non-IC applications and three inches from insulation when installed in IC-rated environments.
Certified by CSA to meet U.S. and Canadian standards, the luminaire complies with UL wet location covered ceiling requirements and is manufactured in accordance with the “Standards for Safety.” Conducted emissions are controlled under MIL-STD-461-G standards, ensuring electrical performance consistency in sensitive facilities. The product is assembled in the USA and meets Buy America(n) procurement requirements under FAR, DFARS, and DOT regulations—reinforcing its compliance for government and institutional projects.
With a combination of optical precision, robust construction, versatile control integration, and hygienic finish options, the EVO 4" Surgical Suite Downlight establishes a high standard for performance-driven environments such as healthcare, laboratories, and clean manufacturing spaces. It delivers consistent, comfortable, and compliant light distribution while offering the serviceability and design adaptability that modern architectural and medical facilities demand.
