The EVO® 6" Square Cleanroom LED Downlight is purpose-built for environments that demand exceptional cleanliness, visual comfort, and reliability under the strictest conditions. Engineered to meet the challenges of ISO 5 (Class 100) cleanrooms, healthcare facilities, educational institutions, and other specialized spaces, this recessed luminaire combines precision optical control with superior environmental protection.
The optical system incorporates EVO® batwing distribution, which produces a uniform, wide-angled layer of light across horizontal and vertical surfaces, eliminating hot spots, bright rings, and harsh contrast. With a 45° cutoff and Bounding Ray™ optical technology, it ensures outstanding glare control and smooth light transitions that support visual comfort in high-sensitivity environments. The luminaire maintains a medium-wide beam angle and is available with flush or regressed lens configurations, allowing specifiers to achieve both performance and aesthetic balance depending on the ceiling and room design.
Performance is central to this cleanroom-rated downlight. Offering a lumen range from 250 to 4,000 lumens, it meets the needs of both general lighting and precision tasks. The fixture’s luminous quality remains consistent through 2.5 MacAdam ellipse color uniformity and CRI options of 85 or 90, maintaining color stability and fidelity throughout its 60,000-hour lifetime with 70% lumen maintenance. The luminaire carries CSA Wet Location certification, an IP66 room-side rating, and is compliant with NSF2 Non-Food/Splash Zone requirements, ensuring it withstands pressurized washdowns, vapor exposure, and particulate contamination.
Every unit is fully serviceable and upgradeable, allowing access to both the lensed LED light engine and the driver from above or below the ceiling. The unitized optical assembly secures the light engine to the reflector for complete optical alignment, ensuring consistent performance over time. The design is complemented by marine-grade materials, antimicrobial finishes, and wipe-down lens options that inhibit bacterial growth, meeting the rigorous hygiene demands of cleanrooms and healthcare environments.
The downlight’s construction employs a 16-gauge galvanized steel housing with preinstalled telescopic mounting bars adjustable between 15 and 32 inches and offering up to 4 inches of vertical movement. It accommodates ceilings up to 1½ inches thick and supports tool-less post-installation adjustments. The assembly is mechanically robust, able to withstand vibration and shock, and includes proper thermal spacing to maintain optimal operation within 25°C ambient temperature. For insulated ceilings, a 3-inch clearance from insulation is required unless otherwise noted.
Electrical performance is equally dependable. The luminaire operates across 120–277 VAC, maintaining a power factor of 90% or greater and driver efficiency above 80% at full load. It meets Sound Rating A+ and complies with ROHS standards. The driver remains inaudible in a 24 dB environment, stable through voltage fluctuations, and capable of flicker-free dimming down to 0.1% of full output in compliance with IEEE P1789 standards. Available dimming configurations include 0-10V, DALI, and DMX, with eldoLED ECOdrive and SOLOdrive options supporting both linear and logarithmic dimming curves.
Control integration is seamless through nLight® wired and wireless systems, allowing connected lighting management and networked dimming functions. The fixture can also be configured with emergency battery backup or paired with generator backup devices to maintain illumination during power interruptions.
A variety of trim options enable functional and aesthetic customization, including flush or regressed lenses in white, black, or antimicrobial finishes. These trims—available as DFR, DFF, DFRBR, DFFBR, DFRAMF, and DFFAMF models—are specifically crafted for hygienic environments that require easy cleaning and contamination resistance.
Every EVO® Cleanroom Downlight undergoes rigorous testing to LM-79 and LM-80 standards in accredited laboratories, ensuring long-term photometric accuracy and stability. Luminaires are CSA certified to U.S. and Canadian standards and fully compliant with UL safety requirements. Color appearance across fixtures remains consistent over time, staying within a <2.5 MacAdam ellipse tolerance, guaranteeing uniformity across installations.
With its wipe-clean surfaces, antimicrobial coatings, sealed IP66-rated enclosure, and vandal- and tamper-resistant construction, the EVO® 6" Square Cleanroom LED Downlight stands as a benchmark for cleanliness, reliability, and precision in light quality. It offers architects, engineers, and lighting designers a high-integrity lighting solution that upholds both stringent cleanroom protocols and architectural performance expectations.
