GE Quartzline 36902 (EKZ) MR16 Halogen Lamp — 30W | 10.8V Low Voltage | Dichroic Reflector | GX5.3 Base

The GE Quartzline® Multi-Mirror® 36902 (EKZ) Lamp is a commercial-grade, high-intensity low-voltage tungsten halogen reflector capsule engineered exclusively for 16mm movie projection gates, clinical dental operatory examination tracks, biomedical laboratory microscopes, and high-precision optical inspection instruments. Delivering a highly concentrated light field with a sharp color temperature of 3100K, this premium single-ended bulb features an industry-standard ANSI EKZ specification tracking profile and utilizes an advanced dichroic cold-beam multi-mirror reflector to achieve a flawless color rendering index of 100 CRI. Outfitted with a standard GX5.3 bi-pin base and an open-face unshielded quartz envelope, it ensures perfect optical focus convergence across its 200-hour rated average service life.

ADL Supply Expert Application & Replacement Guide

The GE EKZ 36902 low-voltage reflector capsule is an established medical, optical screening, and cinematography baseline specified universally across clinical dental operatories, sub-stage microscope illuminators, high-magnification technical testing bays, and historical 16mm movie projection systems. Outfitted with an axially oriented CC-6 coiled-coil tungsten filament aligned to precise mathematical tolerances inside a faceted dichroic cold-beam shell, this lamp projects a highly uniform, concentrated center-beam light field. This allows laboratory technicians, dental surgeons, and optical engineers to capture absolute structural contrast across target planes without experiencing the focal gaps common in non-calibrated alternative replacements.

Critical 10.8V Low-Voltage Parameters and Mechanical GX5.3 Seating Controls: Field contractors and electrical gaffers executing routine equipment maintenance must monitor circuit metrics closely prior to checkout: this lamp runs natively on low-voltage 10.8V line tracks and requires a compatible step-down magnetic transformer or stabilized electronic power supply to operate safely. Connecting or bridging this low-voltage capsule directly across standard domestic 120V AC or 277V AC mainline branch circuits will trigger instant high-amperage over-drive destruction, prompting immediate filament vaporization and an explosive quartz capsule breakdown.

Furthermore, the heavy-duty GX5.3 base features round dual pin contacts spaced on a precise 5.3mm pitch width. Push the lamp pins straight and completely into the socket receiver blocks until the rear reflector shell seats fully flush inside the fixture gate block. Because driving a continuous current load of 2.78 Amperes inside a compact MR16 housing forces the terminal junctions to approach high thermal limits, any loose pin seating or spring clip relaxation will create high contact resistance. This resistance introduces a rapid localized thermal feedback loop that will transcend safe thresholds, melting the fixture base or fracturing the quartz pinch-seal.

Operation, Safety & Mounting Compliance

High-Temperature Regenerative Halogen Halide Cycle Controls

This halogen lamp operates via an internal chemical loop where vaporized tungsten particles bond with halogen gas molecules inside the heated chamber. This compound cycles back onto the burning filament tracks, redepositing the tungsten to preserve filament mass. For this cycle to work cleanly and prevent wall-blackening, the inner envelope must continuously transcend a high temperature threshold exceeding 250°C, making proper convective venting inside projector housings or laboratory instrument shrouds mandatory.
