**New LED Lighting Systems** The HYL 52 LED lighting system is designed to illuminate bio reactors, fermentors and sanitary vessels. The HYL 52 light is a fused glass light which provides a high intensity, cold light source to allow the process to be viewed under a true white light (5000° K color temperature) while adding no heat to the process, which would cause product bake-on. The HYL 52 LED lighting package provides a compact, cost effective, maintenance free lighting system to meet all of your sanitary process needs. No more changing bulbs!
