Kenosha, Wisconsin (June 30, 2026) – Kenall Lighting introduces the next generation of SimpleSeal CSEDI and CSEDO recessed cleanroom luminaires, redesigned to meet the evolving demands of critical environments. With enhancements focused on visual performance, space optimization, and simplified installation, the updated fixtures deliver meaningful gains while maintaining the environmental integrity required in controlled spaces.
Now standard across both series, 90 CRI improves color rendering and visual clarity without sacrificing efficiency, supporting detailed tasks in environments where precision matters. A reduced housing depth of just 2.5 inches allows for more available plenum space to accommodate essential systems such as HEPA filtration and HVAC. Durability and serviceability are improved with use of field replaceable LEDs. The addition of die-cast swing arms simplifies installation.
Designed for flexibility, this luminaire series supports both flange and grid ceiling systems, simplifying specification and installation across projects. Suitable for ISO Class 3–8 cleanrooms, both fixtures are certified accordingly to maintain specialized environmental integrity while delivering consistent, high-quality illumination for critical tasks.
For spectrally sensitive applications, the series includes phosphor-converted 570 nm amber, native 590 nm amber, 630 nm red, and 660 nm deep red options. Optional tunable white technology allows facilities to adjust color temperature throughout the day. This supports circadian alignment for staff, helping maintain alertness, reduce eye strain, and improve task accuracy in demanding environments.
“By focusing on the details that matter most to cleanroom environments, we’ve enhanced performance, reduced installation time, improved serviceability, and created more usable space where it is needed,” said Tim Stevens, Senior Product Manager at Kenall Lighting. “The next generation of SimpleSeal CSEDI and CSEDO reflects our commitment to delivering reliable, high-quality solutions for critical applications.”
