Product Overview

The GE 37527 EHA Quartzline is a precision tungsten halogen projection lamp engineered for fiber optic illuminators and overhead projection systems. At 500W/120V with 11,000 lumens, 3300K color temperature, and a C-13D filament in a compact T6 envelope (3" MOL, 0.75" diameter), this lamp delivers high-intensity, concentrated illumination for optical systems requiring precise filament geometry and consistent color output.

The GZ9.5 oriented base is a keyed 2-pin base with a specific rotational orientation — the lamp must be inserted in the correct alignment for the filament to register precisely within the optical system. Incorrect orientation will degrade projection performance. The 50-hour rated life is standard for a 500W high-output projection lamp operating at rated voltage — confirm supply voltage does not exceed 120V to maximize lamp life.

Compatible Applications

Fiber optic illuminators — High-intensity tungsten halogen source for fiber optic lighting systems requiring ANSI EHA-designated lamps.
Overhead projection systems — Precision projection lamps for overhead projectors and optical instruments requiring GZ9.5 base lamps.
Specialty optical equipment — Professional optical systems where C-13D filament geometry and 3300K output are specified.

Before Ordering — Verify

ANSI Code: Confirm the existing lamp or equipment manual specifies EHA.
Voltage: Confirm equipment is rated for 120V. Operating above rated voltage dramatically shortens lamp life.
Wattage: Confirm the fixture or instrument is rated for 500W.
Base Type: Confirm the socket accepts a GZ9.5 Oriented Medium 2-Pin base. The GZ9.5 is an oriented base — orientation matters for filament alignment.
Physical Fit: Confirm 3" MOL and 0.75" 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.
Correct Orientation Required: The GZ9.5 oriented base must be seated in the correct rotational position. Confirm lamp alignment matches the equipment's lampholder orientation.
Allow Cooling: Allow the lamp and equipment to cool fully before handling or replacement — this lamp operates at very high surface temperatures.
High-Pressure Lamp: Handle with care. Inspect for cracks or damage before installation. Do not use a damaged lamp.
Do Not Exceed Rated Voltage: Operating above 120V shortens lamp life significantly.
