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.

Key Features

  • Ultra-compact design for easy integration into tight spaces
  • Powerful LED light output for clear, shadow-free visibility
  • Perfect for combined sight/light ports or two-flange configurations
  • Cold-light technology – no heat radiation into the process
  • Excellent for chemical, biological, and food-grade processes
  • Vibration-resistant performance ideal for mixers and agitators

Ideal Applications
