USL03 LED
- Product Code: USL03 LED
Ultra-Compact LED Luminaire – High-Performance Lighting for Non-Ex Process Applications
This ultra-compact LED sight glass luminaire delivers bright, high-contrast illumination for bioreactors, laboratory mixers, filtration systems, tanks, agitators, separators, pipelines, and other closed process vessels operating in non-explosive environments. Engineered for professional-grade visibility, it supports hygienic applications, making it an excellent choice for food processing operations.
Designed for universal installation, the unit integrates seamlessly with both combined sight/light ports (single-flange setups) and dual-port systems requiring separate light and visual access points.
