Product Overview

The GE 88621 EGR Quartzline Halogen Lamp is a 750-watt, 120-volt SSTV lamp delivering 21,000 initial lumens at 3200K with CRI 100. It features a G22 medium bi-post base and a T7 bulb shape, making it suitable for high-output stage, studio, and broadcast fixtures. The 3200K color temperature matches professional camera white balance, while CRI 100 ensures perfect color rendering for film, video, and live production.

The C-13D filament and compact T7 envelope (5.0-inch MOL, 0.75-inch diameter) fit standard ellipsoidal spotlights, Fresnel fixtures, and follow spots. With a rated life of 200 hours, this lamp is optimized for applications where maximum brightness per watt is prioritized over extended life – ideal for high-intensity key lighting and long-throw follow spots. Burn position is base-down only – verify fixture orientation before ordering.

Why Choose This Product

• 21,000 lumens – high output for 750W: Excellent brightness for key lighting, follow spots, and long-throw applications in large venues.
• ANSI EGR – industry-standard replacement: The EGR code guarantees consistent electrical and photometric performance for compatible fixtures.
• 3200K studio white – broadcast-matched color: Camera systems set to 3200K tungsten white balance reproduce colors accurately under this lamp.
• CRI 100 – perfect color rendering: Full-spectrum halogen light ensures accurate color reproduction without spectral gaps.
• G22 medium bi-post base: Provides secure, high-current connection for reliable operation in professional luminaires.
• Compact T7 bulb: 0.75-inch diameter and 5.0-inch MOL fits tight optical systems in ellipsoidal spotlights and follow spots.

Applications

• Film and broadcast lighting – high-output Fresnel and open-face fixtures
• Stage and theater – ellipsoidal spotlights, follow spots, large Fresnel luminaires
• Studio and entertainment production – key and fill lighting for large sets
• Concert and live event lighting – long-throw spotlights and wash fixtures

Compatibility & Replacement

Fixture type: This ANSI EGR lamp fits professional stage and studio fixtures designed for a G22 medium bi-post base and 750W/120V halogen lamps. Common in ellipsoidal spotlights, follow spots, and large Fresnel fixtures from manufacturers such as Altman, Strand, and others.

Base: G22 – a two-pin bi-post base with 22mm spacing between contacts. Confirm your fixture uses G22 lampholders (not G9.5, G38, or GX38).

Ballast: No ballast required – operates directly on 120V mains power.

Before ordering, confirm:

• ANSI code – EGR: Verify your fixture specifies ANSI EGR or equivalent 750W/120V G22 halogen lamp.
• Voltage – 120V: Verify fixture and supply circuit are 120V.
• Base type – G22: Physically confirm your fixture uses G22 bi-post lampholders.
• Burn position – base down only: This lamp is rated for base-down operation only. Do not use in horizontal or base-up fixtures.
• Physical dimensions: Verify your fixture accepts a T7 bulb with 5.0-inch overall length and 0.75-inch diameter.
• Fixture wattage rating: Ensure fixture is rated for at least 750W.

Safety & Handling Notes

• High pressure warning – face shield required: Quartzline lamps operate under high internal pressure. Always wear a face shield and protective gloves during handling and installation. Lamp burst can cause serious injury.
• No bare hands: Never touch the quartz envelope with bare skin. Oils cause hot spots leading to premature failure or lamp burst. Use clean gloves or a lint-free cloth.
• Do not exceed rated voltage: Operating above 120V dramatically shortens lamp life. Verify supply voltage before installing.
• Burn position – base down only: This lamp is rated for base-down operation only. Incorrect orientation (horizontal or base-up) can cause premature failure or lamp burst.
• Extreme heat and UV output: Use only in approved enclosed luminaires with appropriate UV filtering.
• Allow complete cool-down before handling: Allow lamp to cool completely before relamping. Do not touch immediately after switching off.
• Follow your fixture manufacturer's service documentation for lamp replacement procedures.
