Product Overview
The GE 23847 Quartzline T2.5 is a pressurized double-ended quartz halogen lamp purpose-built for airport and airfield visual guidance fixtures, where lamp substitution can affect optical output, beam placement, maintenance intervals, and overall fixture performance. This lamp operates on 6.6A constant-current series airfield lighting circuits — common in runway, taxiway, approach, and threshold lighting systems — and is not interchangeable with constant-voltage lamp variants without confirming fixture compatibility.
As a double-ended pressurized lamp, this product carries specific handling and installation requirements beyond typical single-ended halogen lamps: it must be used only in an enclosed fixture rated for this product, and operating voltage must never exceed 110% of rated value. For best results and fixture warranty compliance, replace like-for-like using the exact GE order code and current fixture documentation.
Compatible Applications
- Runway edge and centerline lighting
- Taxiway edge and centerline lighting
- Approach/end lighting and threshold lighting
- PAPI and airfield visual guidance systems
- Airport beacon, obstruction, and guidance-sign fixtures where specified
- FAA/ICAO fixture maintenance programs where the fixture calls for this exact lamp type
Before Ordering — Verify
- GE Order Code: Confirm the installed lamp or fixture documentation calls for GE 23847 / Q6 6A/T2 1/2/1CL.
- Electrical Rating: Confirm the fixture operates on a 6.6A constant-current circuit and is not a different airfield circuit type.
- Wattage: Confirm the fixture is rated for 45W operation.
- Base Type: Confirm the socket or connector matches Bi-Pin (Special).
- Burn Position: Not specified by the manufacturer — confirm the required burn position against your fixture documentation before ordering.
- Physical Fit: Confirm 1.75" MOL and 0.312" diameter fit within fixture clearance. LCL is not published — verify against fixture documentation if critical to your application.
- Voltage Limit: Confirm circuit voltage will not exceed 110% of this lamp's rated voltage at any point.
Safety and Installation Guidelines
- Pressurized Lamp Warning: Unexpected rupture may cause injury, fire, or property damage. Avoid direct water, liquid, or metal contact. Do not exceed 110% of rated voltage. Use only in an enclosed fixture rated for this product.
- Risk of Fire: Keep combustible materials away from the lamp. Use only in an enclosed fixture rated for this product.
- Risk of Electric Shock: Turn power off before inspection, installation, or removal.
- Risk of Shattering/Injury: Lamp may shatter and cause injury if broken. Do not use if the outer glass is scratched or broken. Dispose of lamp in a closed container.
- Risk of Burn: Allow lamp and fixture to cool completely before handling. Turn power off before installing.
- Qualified Installation: Airport, airfield, and aviation lamps should be installed by qualified maintenance personnel following fixture and site procedures.
- Handle Carefully: Use clean gloves or a lint-free cloth to avoid quartz contamination.
- Use Correct Replacement: Do not substitute lamps unless the fixture manufacturer or maintenance documentation permits it.
Compliance
- UPC 043168238472 / GTIN 10043168238479.
- Verify FAA/ICAO compliance requirements and RoHS status with the GE manufacturer specification sheet prior to use in regulated airfield installations.
