GE 11482 EXM Airfield / Aviation Lamp - 45W 6.6A T3.5

GE 11482 EXM — 45W 6.6A amperes T3.5 Projection Lamp, GZ9.5 2-Pin Base

The GE EXM (order code 11482) is a 45W projection lamp rated at 6.6A amperes, built on a T3.5 bulb with a GZ9.5 2-Pin base and a C-8 filament. Rated life is 1000 hours. Colour temperature is 2950K. Initial output is 750 lumens. Maximum overall length is 1.75 in with a light centre length of 1.00 in. Burn position is restricted: Base Down to Horizontal — do not operate base above horizontal. Typical application: Airport. Projection lamps are matched to specific optical systems — confirm the ANSI code, base, light centre length, and burn position against the equipment before ordering.

Technical Specifications

Product Overview

Projection lamps are precision optical sources. Unlike general lighting lamps, they are built with tailored filaments positioned to close tolerances so that the light source sits exactly where the equipment's optical system expects it. That is why light centre length and burn position appear on the specification alongside wattage and voltage: a lamp with the right base and wattage but the wrong filament position will not focus correctly.

This is a Quartzline® halogen lamp. The quartz envelope and halogen fill cycle return evaporated tungsten to the filament, so the bulb does not blacken or blister as an ordinary incandescent lamp does. Light output and colour temperature stay effectively constant across the life of the lamp, which matters in projection, copyboard, and printing work where exposure has to be repeatable.

Burn position matters on this lamp. It is rated HD: Base Down to Horizontal — do not operate base above horizontal. Operating outside that range shortens life and can cause early failure, because the halogen cycle and the mechanical support of the filament are both designed around the intended orientation.

Compatible Applications

• Airport (GE listed application)
• Airport runway and approach lighting
• Constant-current series circuits
• Replacement lamp for equipment specified with ANSI code EXM

Before Ordering — Verify

• Confirm the equipment calls for ANSI code EXM. ANSI codes assure mechanical and electrical interchangeability between manufacturers, so this is the primary cross-reference.
• Confirm the base is GZ9.5 2-Pin.
• Confirm this is a series (constant current) circuit rated at 6.6 amperes. Amp-rated lamps are not interchangeable with voltage-rated lamps and the wattage shown is an approximate initial value at rated amperes.
• Confirm the required light centre length is 1.00 in. LCL positions the filament relative to the base and determines whether the lamp focuses correctly in the equipment.
• Confirm the equipment accommodates a maximum overall length of 1.75 in. Listed lengths include maximum tolerances, so actual lamps are generally slightly shorter.
• Confirm the equipment holds the lamp in a permitted burn position. This lamp is rated HD: Base Down to Horizontal — do not operate base above horizontal.
• Note the 1000 hour rated life when planning spares. Rated life is a laboratory median at rated voltage, not a service life guarantee — shock, vibration, voltage fluctuation, and temperature can all shorten it.
• Confirm case quantity — the manufacturer case quantity for this order code is 24.
• GE lists warning and caution notice A against this lamp. Refer to GE's published notices for this order code before installation.

Safety and Handling Guidelines

• Disconnect power and allow the lamp to cool completely before handling or replacement. Projection lamps run at high temperature and stay hot well after switch-off.
• Do not touch the quartz envelope with bare hands. Skin oils cause localized overheating of the quartz and can lead to premature failure or rupture. Clean with isopropyl alcohol if the envelope is touched.
• Quartz halogen lamps operate under pressure. Operate only within an enclosed housing or the equipment for which the lamp is specified.
• Seat the lamp fully in its socket. A partially seated lamp can arc at the contacts and overheat the lampholder.
• Observe the HD burn position restriction. Operating outside the permitted orientation shortens life and can cause early failure.
• Ensure the equipment provides the cooling airflow it was designed with. Projection lamps depend on forced or convected air to stay within their thermal limits.
• Keep combustible materials clear of the lamp and lamphouse.
• Do not exceed the rated current. Overvoltage operation sharply reduces lamp life.
• Follow the equipment manufacturer's instructions for lamp installation and alignment.
• This lamp contains no mercury. Recycle or dispose of it in accordance with local requirements.

Compliance

• GE warning and caution notice reference: A. Refer to GE's published notices for this order code before specification or installation.
• Contains no mercury. Not subject to mercury lamp disposal or shipping restrictions.
• Rated life is stated per ANSI standard design life.
• Dispose of in accordance with local regulations.
