Using the latest technology of LED illumination, this Lumiglas light provides up to 11 years of reliable, maintenance-free operation. The light is extremely durable as it is resistant to shock and vibration. No heat is directed inside the vessel to protect process media from additional heat exposure. The housing is available in aluminum (ASL55 Light) or stainless steel (ESL55 Light), both with either a mounting bracket or sanitary clamp connection.
