Product Overview

The GE GLA (P/N 88424) is a 575-watt 115-volt SSTV halogen lamp from the GE Quartzline professional entertainment platform. ANSI GLA classification, G9.5 bipin base, and universal burn position make this a flexible professional lamp for the full range of SSTV applications — film and broadcast production, stage lighting fixtures, follow spot and spotlight systems, and continuous-source photography and photoflood lighting.

The 115V rated voltage is the key specification that distinguishes the GLA from the ANSI FLK (also 575W but rated 120V). This is not a trivial distinction — operating a 115V lamp at 120V over-drives the filament, shortens lamp life significantly, and may cause premature failure. The GLA is specifically calibrated for the nominal 115V supply voltage used in some professional entertainment and broadcast facilities, where building supply voltage is regulated to 115V or where the fixture includes a voltage-regulating transformer. Verify your supply voltage against the lamp’s rated voltage before ordering.

At 3050K, the GLA produces a slightly warmer color temperature than 3100K (FLK) or 3200K (studio-standard BWA) sources — appropriate for theatrical applications and follow spot systems where warmer light quality is preferred, or for venues where the building supply voltage is maintained at 115V nominal. CRI 100 full-spectrum halogen output renders all visible wavelengths accurately through gels and filters.

Note on missing specifications: Initial lumens, rated average life, filament type, MOL, and bulb diameter are not stated in the available source data. Verify these specifications with the GE product data sheet for P/N 88424 / ANSI GLA before specifying for maintenance planning, fixture clearance verification, or performance calculations.

Why Choose This Product

• ANSI GLA — correct specification for 115V stage circuits: The GLA is calibrated for 115V supply voltage — specifying an FLK (120V) on a 115V circuit will under-drive the filament; specifying a GLA on a 120V circuit will over-drive it. ANSI code matching to supply voltage is the critical specification decision for this lamp.
• 575W SSTV output — professional entertainment performance: Matched-wattage replacement for professional stage ellipsoidals, follow spots, and Fresnel fixtures in the 575W class.
• 3050K warm white — flattering theatrical color temperature: Slightly warmer than 3100K (FLK) or 3200K (studio) — appropriate for theatrical and follow spot applications where warmer light quality is preferred for skin tones and gel interaction.
• CRI 100 — full-spectrum halogen accuracy: Continuous-spectrum output renders all colors with perfect accuracy through gels and filters.
• G9.5 bipin base — stage standard: Standard professional stage lampholder base for 575W class fixtures. Verify G9.5 vs GY9.5 vs GX9.5 pin designation with your fixture documentation before ordering.
• Universal burn position: Operates in any orientation — appropriate for diverse fixture mounting positions.
• Follow spot compatibility: Universal burn position and G9.5 bipin base make this lamp appropriate for follow spot and spotlight systems requiring 575W SSTV halogen performance at 115V.

Technical Specifications

115V vs 120V — Why Rated Voltage Matters for Stage Halogen

Stage halogen lamps in the 575W class are available at multiple voltage ratings — commonly 115V (GLA), 120V (FLK), and 115–120V dual-rated. Using the wrong voltage lamp for your supply circuit affects performance and lamp life:

• Running a 115V lamp on a 120V supply: The lamp operates 4.3% over rated voltage — filament temperature increases, color temperature rises, lumen output increases slightly, and lamp life decreases significantly. Even a small overvoltage can halve lamp life.
• Running a 120V lamp on a 115V supply: The lamp operates under-voltage — filament temperature decreases, color temperature drops toward warmer/redder, lumen output decreases, and lamp life extends. Shifts photometric performance away from the design specification.
• Correct specification: Order ANSI GLA (115V) if your facility maintains 115V supply voltage. Order ANSI FLK (120V) if your supply is 120V nominal. Measure your actual supply voltage at the fixture with a voltmeter under load if you are unsure.

Applications

The GE GLA 575W/115V is specified for professional entertainment lighting applications where the fixture supply voltage is 115V nominal:

• Stage and theatrical lighting – Ellipsoidal spotlights, Fresnel fixtures, and PAR units in theatrical venues where building supply voltage is maintained at 115V, or where voltage-regulating transformers reduce supply to 115V for lamp compatibility.
• Follow spot and spotlight systems – Professional follow spot fixtures specifying ANSI GLA 575W/115V halogen for consistent output performance at rated voltage.
• Film and broadcast production – On-set and studio lighting fixtures operating on regulated 115V supply circuits where maintaining rated voltage extends lamp life on demanding production schedules.
• Concert and touring lighting – Touring rigs where supply voltage is regulated to 115V by onboard power distribution or generator regulation.
• Photography and photoflood – Continuous-source studio lighting on 115V regulated supply where 575W halogen output at 3050K is specified.

Replacing Your Current SSTV Halogen Lamp?

Confirm the following before ordering:

• ANSI code — GLA: Verify your fixture specifies ANSI GLA. GLA is not interchangeable with FLK (120V), FEL (1000W/120V), or other 575W ANSI codes. The key distinguishing factor between GLA and FLK is voltage rating.
• Voltage — 115V: This lamp is rated 115V. If your supply is 120V nominal, the ANSI FLK is the correct specification. Measure with a voltmeter before ordering if unsure.
• Base type — G9.5 bipin: Confirm exact pin spacing designation (G9.5, GY9.5, or GX9.5) with your fixture documentation before ordering.
• Burn position: Universal — no orientation restriction.
• Initial lumens, rated life, and dimensions: Confirm with the GE product data sheet for P/N 88424 / ANSI GLA before specifying for footcandle calculations or maintenance planning.
• Wear face shield and protective gloves: SSTV lamps operate under high internal pressure — required PPE during handling and installation.
• Do not touch the bulb with bare hands: Use clean gloves or a lint-free cloth.

Safety and Handling Guidelines

• High pressure warning — face shield required: SSTV lamps operate under high internal pressure. Always wear a face shield and protective gloves during handling and installation.
• No bare hands: Never touch the bulb envelope with bare skin. Use clean gloves or a lint-free cloth.
• Do not exceed rated voltage: Operating above 115V shortens lamp life significantly. Verify supply voltage before installing.
• Extreme heat and UV output: SSTV lamps operate at very high temperatures with significant UV output. Use only in approved enclosed luminaires with appropriate UV filtering.
• Allow complete cool-down before handling: Allow the lamp to cool completely before handling or relamping.
• Follow your fixture manufacturer’s service documentation for lamp replacement procedures.

Compliance and Certifications

• Verify UL listing status with manufacturer specification sheet.
• Verify RoHS compliance status with manufacturer specification sheet.
• Verify FDA radiation performance compliance with manufacturer specification sheet.
• Verify Prop 65 warning requirements with manufacturer specification sheet.

ADL Supply recommends confirming all applicable compliance data with the GE official product data sheet (ANSI GLA / P/N 88424) prior to specification or installation.
