Technical Specifications

DoorframeStandard 20-gauge cold rolled steel. One-piece inset style construction with welded corners. Steel and Aluminum selections are finished with gloss white TGIC polyester powder coat finish with 5-stage pre-treatment. Optional 20-gauge type 304 stainless steel (#4 finish-post fabrication). Antimicrobial finish standard on all exposed painted surfaces.  Doorframe secured to housing with stainless steel aircraft cables and captive flush-mounted Phillips head stainless steel fasteners - (6) for 1x2, (8) for 1×4 and 2×2, (10) for 2×4. One-piece, closed-cell silicone gasket seals doorframe to housing.
Serviceable mid-power white LED array. Available 3000K, 3500K, 4000K and 5000K color temperatures with maximum 3-step MacAdam variation allowance. Minimum 80 CRI standard with optional minimum 90 CRI (R9 > 50) available. 530 nm green mid-power LED array. 120/277VAC or 347VAC, 50/60Hz electrical input with replaceable high power factor electronic, constant-current driver (<10% THD, >0.90 PF). Minimum 85% driver efficiency. Standard 0-10V dimming with 1-100% range. and dim-to-dark capabilities on white and green circuit. Maximum dimming source current per luminaire 0.4mA (white) / 0.2mA (green). EMC meets or exceeds FCC CFR Part 15 and MIL STD 461F requirements. White and green circuit should be independently powered and dimmed.
HousingStandard 24-gauge cold rolled steel with dust-tight, sealed construction.  Alternate material options available. Rigid housing flange with mitered and welded corners. White TGIC polyester powder coat finish – 5-step pre-treatment. Salt spray test: 1,000 hours. Antimicrobial finish on all exposed painted surfaces of installed luminaire.  Internal surfaces use a proprietary high reflectance coating (Reflectance: >92%). Flange finish matches housing, regardless of doorframe finish.
Non-IC recessed ceiling mounting into grid and flange application types. Flange installation utilizes included adjustable swing-out mounting brackets. Grid installation suitable for 1" and 1.5" T-bar ceilings. Universal installation into grid or flange (drywall) ceiling applications. See below for install frames, optionally used for flange mount in hard ceilings (not required).
Luminaire is certified to UL standards by Intertek Testing Laboratories for Wet Location. ETL certified IP65 per IEC 60598. NSF2 Splash/Non-Food Zone. Meets FED-STD-209E/Class 1 (ISO 3) Cleanrooms. Compliant with MIL-STD 461G for radiated and conducted emissions (including when ordered with LEL option). CCEA Approved.
OpticsInjection-molded, high refraction polycarbonate optics provided for each LED. Proprietary KORE Technology™ (Kenall Optical Radiance Engine) delivers improved visual performance and uniform diffuser luminance (<1.5:1 max/min ratio across full lens area).  Impact-resistant diffused acrylic outer lens.  Symmetric/asymmetric (ASYM) and full-asymmetric (FASYM) optics provide asymmetric throw while retaining uniform luminance.
PhotometricsPhotometry tested to the IESNA LM-79-08 standard. For additional photometric data, please go to
