Product Overview

The GE 12092 EXR Quartzline is a precision halogen MR13 projection lamp engineered for professional slide projectors and photo-optic equipment requiring ANSI EXR-designated sources. At 300W and 82V with a CC-8 filament and 3350K color temperature, it delivers high-intensity, full-spectrum illumination with CRI 100 — essential for accurate slide reproduction and color-critical projection applications.

The 6cm working distance is a critical specification for slide projection systems — the lamp must be positioned at exactly this distance from the condenser or optical element for correct light collection and image brightness. The open face (no cover glass) design requires a properly enclosed optical housing. Confirm ANSI code EXR and working distance match your projector's requirements before ordering.

Compatible Applications

35mm and large-format slide projection — Professional projectors specifying ANSI EXR at 300W/82V.
Photo-optic and optical equipment — Instruments requiring MR13 GX5.3 halogen sources with precise working distance and color temperature.
Retrofit and maintenance replacement — Confirm ANSI code, voltage, wattage, base, and working distance before ordering.

Before Ordering — Verify

ANSI Code: Confirm the existing lamp or projector manual specifies EXR.
Voltage: Confirm equipment transformer output is 82V. Operating above rated voltage dramatically shortens lamp life.
Wattage: Confirm the projector is rated for 300W.
Base Type: Confirm the lampholder accepts a GX5.3 2-pin base.
Working Distance: Confirm your projector's optical system requires a 6cm working distance. This is lamp-specific and affects image brightness and focus.
Physical Fit: Confirm 1.75" MOL and 1.63" diameter fit within your equipment's lamp housing.

Safety and Handling Guidelines

Do not touch the quartz envelope with bare hands. Skin oils cause hot spots leading to premature failure or lamp burst. Use clean gloves or a lint-free cloth. If accidentally touched, clean with isopropyl alcohol before use.
Do Not Exceed Rated Voltage: Operating above 82V dramatically shortens lamp life. Verify transformer output before installation.
Allow Cooling: Allow the lamp and equipment to cool fully before handling or replacement.
Open Face — No UV Protection: This lamp has no cover glass. Use only in projectors and equipment with proper optical housing and UV shielding built into the condenser or optical system.
High-Pressure Lamp: Handle with care. Inspect for cracks or damage before installation. Do not use a damaged lamp.
