Cleanroom lighting plays a critical role in maintaining visibility, contributing to cleanroom cleanability, and control within regulated environments. Beyond delivering proper illumination, the right fixtures help support contamination control, withstand routine cleaning protocols, and integrate cleanly into ceiling systems without disrupting the integrity of the space.
From standard recessed ceiling applications to walkable and top-access plenum environments, cleanroom-ready lighting helps pharmaceutical, biotech, healthcare, and other controlled facilities balance performance, durability, and compliance-driven design from the ceiling down. SPS CleanTech is proud to partner with Kenall to offer their SimpleSeal™ line of LED lighting.
Selecting the right cleanroom light starts with the ceiling system and how the fixture will be accessed for service. Standard recessed cleanroom ceilings typically require a different fixture approach than walkable plenum environments, where maintenance may need to happen from above the clean space.
Kenall’s CSEDI, CSEDO, and CSSETO models each support cleanroom-ready performance, but are designed for different installation conditions and maintenance priorities.

| Model | Best For | Key Advantage |
|---|---|---|
| SimpleSeal® CSSETO | Walkable plenums and composite modular ceiling systems | Top-access design with a true-flat, walkable surface for cleanrooms where maintenance from above is preferred or required |
| SimpleSeal® CSEDI | Standard recessed cleanroom ceilings using grid or flange applications | Inset doorframe design for clean, reliable recessed installation in controlled environments |
| SimpleSeal® CSEDO | Recessed cleanroom applications with heightened cleanability requirements | Overlapping doorframe with a progressive cleaning surface, making it well-suited for spaces where wipe-down performance and sanitation are key priorities |
For facilities with walkable plenums or modular ceiling systems, CSSETO is the strongest fit. Its top-access design allows maintenance from above the cleanroom, helping reduce disruption to operations below.
For standard recessed ceiling applications, CSEDI and CSEDO are the primary options. CSEDI is a strong choice for cleanroom projects that need a low-profile, recessed luminaire with dependable sealed performance. CSEDO is better suited when the project calls for an overlapping doorframe design and enhanced cleanability at the room-side surface.
Cleanroom lighting must support the conditions of the environment, from sealed ceiling integration to routine cleaning and specialized illumination needs. Kenall SimpleSeal® cleanroom luminaires are designed to help controlled facilities maintain cleanability, durability, and consistent visual performance.
SimpleSeal® CSSETO delivers top access for cleanrooms with walkable plenums and composite modular ceilings. A true-flat, flush top surface and dual‑side serviceability support safe maintenance. The independently sealed IP66 optical chamber ensures protected performance, while multiple spectral options provide uniform illumination
Key Features








Built for modern cleanrooms, these recessed luminaires deliver sharper visibility, faster installation, and more usable space. Standard 90 CRI ensures clear, accurate lighting, while a slim 2.5″ housing frees plenum space for critical systems. Field-replaceable LEDs and die-cast swing arms simplify maintenance and installation. Certified for ISO Class 3–8 environments and compatible with flange or grid ceilings, they offer flexible, reliable performance. Optional spectral outputs and tunable white support precision work and staff comfort.
