Product Overview

The GE 23734 FDN Quartzline Halogen Lamp is a 500-watt, 120-volt SSTV lamp delivering 12,800 initial lumens at 3200K with CRI 100. It features an R7s recessed single contact base and a frosted T3 bulb, making it suitable for stage, studio, and theater fixtures that require a linear, double-ended halogen source with warm studio-white color temperature and excellent color rendering.

The C8 filament and compact T3 envelope (4.7-inch MOL, 0.4-inch diameter) fit standard linear halogen fixtures, including certain striplights, floodlights, and accent luminaires. With a 400-hour rated life, this lamp balances output and longevity for professional entertainment applications. Burn position is strictly horizontal (within 4° of level) – verify fixture orientation before ordering.

Compatibility & Replacement

Fixture type: This ANSI FDN lamp fits professional stage and studio fixtures designed for an R7s recessed single contact base and 500W/120V linear halogen lamps. Common in striplights, border lights, cyclorama floods, and certain accent fixtures.

Base: R7s – a recessed single contact base with spring-loaded ends, standard for linear halogen lamps. Measure your existing lamp's length to confirm compatibility (this lamp has 4.7-inch MOL).

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

Before ordering, confirm:

• ANSI code – FDN: Verify your fixture specifies ANSI FDN or equivalent 500W/120V R7s linear halogen lamp.
• Voltage – 120V: Verify fixture and supply circuit are 120V.
• Base type – R7s: Confirm your fixture uses R7s recessed single contact lampholders (spring-loaded ends).
• Burn position – horizontal only: This lamp must be operated horizontally within 4° of level. Do not use in vertical or tilted fixtures.
• Physical dimensions: Verify your fixture accepts a T3 bulb with 4.7-inch overall length and 0.4-inch diameter.
• Fixture wattage rating: Ensure fixture is rated for at least 500W.

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 – horizontal only (within 4° of level): This lamp is rated for horizontal operation only. Incorrect orientation (vertical or tilted) 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.
