Kenosha, Wisconsin (February 3, 2026) – Kenall Lighting introduces the SimpleSeal® CSSETO, the newest troffer series in its top access lighting portfolio. This fixture series, designed for cleanrooms with walkable plenum spaces and composite modular ceilings, features a true flat, flush top surface that supports safe, efficient top-side maintenance without disrupting processes below. Dual-side serviceability gives the CSSETO the flexibility these spaces need, enabling maintenance from either side when service is required.
Engineered for performance and visual comfort, the SimpleSeal CSSETO delivers enhanced lens luminance and 90 CRI with an independently sealed optical chamber that protects internal components, providing true IP66 performance.
“By combining an independently sealed optical chamber, enhanced lens luminance, and high color quality, CSSETO delivers on all fronts: the performance, safety, and serviceability our cleanroom customers expect from Kenall,” said Tim Stevens, Senior Product Manager at Kenall Lighting.
For spectrally sensitive applications, including biopharmaceutical, semiconductor, and specialized research environments, the SimpleSeal CSSETO series offers lighting options in native 590 nm Amber, 630 nm Red, and 660 nm Deep Red to align with process requirements. The series integrates into 2-inch, 3-inch, and 4-inch modular ceiling systems and comes in 1’x4’, 2’x2’, and 2’x4’ sizes to deliver uniform illumination. Along with these configuration options, the CSSETO meets Build America, Buy America requirements, enabling straightforward specification on eligible publicly funded projects and supporting domestic content compliance.
