Technical data
Lumistar LED Sight Glass Light Overview
The Lumistar LED Sight Glass Light is a high-performance industrial illumination system designed for visual inspection of closed process equipment such as tanks, reactors, mixers, silos, and pipelines.
It is engineered to provide bright, uniform, and glare-free illumination through sight glass fittings, enabling operators to clearly observe flow conditions, mixing processes, liquid levels, and product quality in real time.
The luminaire uses advanced LED technology with low heat emission, making it suitable for temperature-sensitive applications in chemical, pharmaceutical, food & beverage, and biotechnology industries. Its robust industrial housing ensures reliable operation in demanding environments with high humidity, vibration, and continuous operation requirements.
Designed for mounting on standard circular sight glass fittings (such as DIN 28120 / DIN 28121 and similar systems), it can be used in combination sight glass + light configurations or separate lighting ports depending on installation requirements.
