Product Overview
![]()
The GE EKE Quartzline Multi-Mirror MR16 (Order Code 35200) is a precision 150W 21V halogen MR16 multi-mirror reflector lamp engineered for fiber optic illuminators, 8mm slide projection systems, dental and medical equipment, and specialty optical instruments requiring a compact, high-output source at a regulated 21V supply. Delivering 3250K warm white output through a GX5.3 2-pin base with a CC-6 filament and 1.75cm typical working distance, this ANSI EKE-coded lamp provides a 250-hour calibrated service life in approved enclosed optical fixture assemblies.

ADL Supply Expert Application & Replacement Guide
The GE EKE Quartzline (Order Code 35200) is primarily used by biomedical equipment technicians, dental equipment service personnel, optical instrument engineers, and AV equipment maintenance teams as the designated replacement lamp in fiber optic illuminators, 8mm slide projectors, dental curing units, medical diagnostic instruments, and specialty optical systems including Bausch & Lomb 31-31-52, Dentsply/Caulk Triad TCU II, Panasonic Monitor, Pro-Dentac Pro Cam C1000, and Trojan Eltra Eye platforms. This lamp operates at 21V from a regulated electronic power supply — it is not compatible with standard 12V MR16 low-voltage transformers, which are the most common supply type for GX5.3-based lamps. The equipment's internal regulated supply must output exactly 21V; do not exceed 110% of rated voltage (23.1V maximum) as noted in the manufacturer's warnings. The burn position is horizontal within ±15° or base-down vertical — base-up vertical mounting is not approved and will affect filament orientation and lamp life. The 1.75cm typical working distance is a precision optical parameter for fiber optic coupling and instrument illumination; confirm this matches your equipment's optical design before ordering.
Before You Order
| Verify Before Ordering 21V Regulated Supply Required — Not Compatible with Standard 12V MR16 Transformers | Horizontal or Base-Down Only This lamp requires a regulated 21V supply — standard 12V MR16 low-voltage transformers are not compatible. Confirm ANSI code EKE and equipment supply voltage before ordering. Burn position is horizontal ±15° or base-down only — base-up vertical is not approved. Do not exceed 110% of rated voltage (23.1V maximum). Enclosed fixture required. Never handle quartz envelope with bare skin. |

Operation, Safety & Mounting Compliance
21V Voltage Specificity, Burn Position & Working Distance
The 21V operating voltage is a specialty regulated supply level used in medical, dental, and precision optical equipment — it is entirely distinct from the 12V supply used with standard GX5.3 MR16 halogen lamps in architectural and display lighting. The equipment's internal regulated power supply must output exactly 21V; operating above 110% of rated voltage (23.1V) creates disproportionate filament stress and will significantly shorten the 250-hour calibrated service life. The horizontal ±15° or base-down burn position restriction ensures the filament operates in the correct orientation relative to gravity — base-up vertical installation causes the filament to sag under gravity at operating temperature, displacing the luminous center from the optical axis of the multi-mirror reflector. The 1.75cm working distance is a precision parameter for fiber optic light guide coupling; substituting a lamp with a different working distance will shift the source image out of the guide's acceptance aperture, reducing coupling efficiency.
Pressurized Envelope, Quartz Handling & Disposal
This is a pressurized halogen lamp — do not use if the outer glass is scratched or cracked, and dispose of broken lamps in a closed container. Never allow the quartz envelope to contact water, liquid, or metal during operation. Never handle with bare skin — skin oils create localized hot spots that accelerate premature failure. Always relamp using clean cotton gloves or a lint-free cloth. Turn power off and allow the fixture to cool completely before installation or removal. This lamp contains no mercury; standard electronic waste disposal applies.
