Product Overview

The Ushio 1000311 EKN JCR17.7V-120W is a 120W 17.7V MR16 halogen reflector lamp for professional audio/visual projection, medical endoscopy, microscopy, dental, and specialty optical illumination. this lamp provides precise, focused output appropriate for optical instruments requiring accurate, stable illumination at 17.7V.

Do not touch the lamp envelope with bare hands. Skin oils cause hot spots leading to premature failure. Use clean gloves or lint-free cloth. Allow full cool-down before handling.

Applications

Medical and dental instruments – MR16 photo-optic halogen for surgical lights, dental operatories, microscopes, and ophthalmic equipment.
Audio/visual projection – Precision reflector for projectors, slide systems, and optical instruments requiring focused output.
Retrofit and maintenance replacement – Confirm ANSI code, wattage, voltage, and base type before ordering.

Safety and Handling

Do not touch the lamp envelope with bare hands. Skin oils cause hot spots leading to premature failure or lamp burst. Use clean gloves or lint-free cloth. Clean with isopropyl alcohol if accidentally touched.
Voltage — 17.7V: Verify your fixture or power supply output matches the rated voltage. Operating above rated voltage significantly shortens lamp life.
Enclosed fixture only: Use only in approved enclosed optical fixtures. Exposure to lamp during operation is a UV/thermal hazard.
Allow 15-minute cool-down before replacement.
