ESL51 LED – Flush-Mounted LED Luminaire for Clear, High-Contrast Process Illumination

The ESL51 LED luminaire provides clean, high-contrast illumination inside vessels, tanks, reactors, agitators, silos, pipelines, and visual flow indicators operating in non-explosive environments. Its compact flush-mounted design delivers excellent optical performance while maintaining hygienic, easy-clean surfaces ideal for sanitary and industrial applications.

Engineered for seamless integration with sight glass fittings, the ESL51 LED is suitable for both combined sight/light ports (single-flange installations) and two-port configurations. An integrated clamp allows direct attachment to the Lumiglas SW I wiper unit, making it a highly versatile lighting solution.
