USL13 / USL33 LED – Compact, High-Performance Illumination for Non-Ex Process Applications

The USL13 LED and USL33 LED luminaires provide bright, reliable illumination for bioreactors, laboratory mixers, filters, tanks, agitators, separators, pipelines, and other closed vessels operating in non-explosive environments. Their compact, high-output LED design ensures excellent visibility without adding heat to sensitive chemical, pharmaceutical, or biological processes.

Designed for universal installation on sight glass fittings, both models deliver powerful cold-light illumination while maintaining hygienic, easy-clean profiles suitable for sterile and food-grade environments.
