Ushio 1000336 ENW ENC JCR19V-80W

The Ushio 1000336 ENW/ENC JCR19V-80W is a precision 80W 19V halogen MR16 specular reflector photo-optic lamp engineered for professional audio/visual projection, medical endoscopy, microscopy, dental operatory lighting, and specialty optical illumination applications. Delivering 600 initial lumens of 3200K output at 100 CRI through a GX5.3 bi-pin base with a CC-6 precision coil filament, this ANSI ENW/ENC-coded lamp provides a 400-hour calibrated service life in approved enclosed optical fixture assemblies.

ADL Supply Expert Application & Replacement Guide

The Ushio 1000336 ENW/ENC is primarily used by biomedical equipment technicians, AV equipment service personnel, and optical instrument engineers as the replacement arc source in medical endoscopy light guides, dental operatory illuminators, research microscopy stages, slide projectors, and specialty optical bench systems where the ANSI ENW or ENC code and 19V regulated supply are the authoritative equipment specifications. This lamp operates at 19V from a regulated power supply built into the instrument — it is not compatible with standard 12V low-voltage MR16 transformers, 21V medical variants, or any other specialty voltage; verify the equipment's internal supply outputs exactly 19V before installation. Over-voltage operation, even marginally above 19V, will significantly compress the 400-hour calibrated service life. The GX5.3 round bi-pin base uses 5.3mm round pin spacing — confirm the fixture socket is standard round GX5.3 before ordering. Burn position is base-down to horizontal only — vertical base-up installation is not approved and will affect filament orientation and lamp life. Production facilities and clinical instrument suites should track runtime hours and establish a preventive replacement interval before the 400-hour rated life threshold.

Operation, Safety & Mounting Compliance

19V Voltage Accuracy, Burn Position & Enclosed Fixture Requirement

The 19V operating voltage is a specialty regulated supply level used in medical, dental, and precision optical instruments — the equipment's internal regulated power supply must output exactly 19V under operating load. Standard 12V MR16 low-voltage transformers used in architectural and display lighting are not compatible. Operating above rated voltage creates disproportionate filament temperature increases that accelerate premature failure of the 400-hour calibrated service life. The base-down to horizontal burn position restriction ensures the filament operates in the correct orientation relative to gravity at 80W operating temperatures — vertical base-up installation causes the CC-6 coil to sag under gravity, displacing the luminous center from the reflector's focal point and degrading optical performance. This is an unshielded quartz halogen reflector and must be operated inside an approved enclosed optical fixture — open-face operation presents UV and thermal hazard and is not permitted.

Quartz Glass Handling & Disposal

Never handle the quartz glass envelope or reflector body with bare skin — skin oils create localized hot spots that accelerate premature envelope failure. If accidental skin contact occurs, clean the envelope thoroughly with isopropyl alcohol and allow to dry completely before powering the fixture. Always relamp using clean cotton gloves or a lint-free cloth. Allow a minimum 15-minute cool-down before relamping. This lamp contains no mercury; standard electronic waste disposal applies.
