Product Overview
This Ushio JCR lamp provides a focused optical beam for projection, microscopy, fiber-optic, dental, medical, scientific, and other specialty equipment requiring an MR16 halogen reflector source. The 50mm reflector profile and specified working distance are critical for correct optical alignment.
Because these are precision photo-optic lamps, the replacement should be matched by Ushio ordering code, lamp description, wattage, voltage, base type, reflector type, and burn position rather than by wattage alone.
