Product Overview

The GE Quartzline Q250MC-ESM (Q250CL/MC) is a professional 250-watt, 120-volt SSTV halogen lamp delivering 4,850 initial lumens at 2950K with CRI 100. It features an E11 mini candelabra screw base and a frosted T4 bulb, making it ideal for stage, studio, theater, and broadcast fixtures where a warm white, long-life halogen source is required.

GE Quartzline halogen SSTV lamps are widely used in professional stage fixtures, television studios, film production, and theater lighting. The 2,000-hour rated life significantly reduces maintenance frequency compared to standard stage lamps, while the CC-8 filament provides stable, intense light output. The frosted finish helps diffuse light for smoother beam quality.

Compatibility & Replacement

Fixture type: This ANSI ESM lamp is designed for professional stage and studio fixtures that accept an E11 mini candelabra base and 250W/120V halogen lamps. Common in smaller ellipsoidal spotlights, accent fixtures, and specialty luminaires.

Base: E11 (Mini Candelabra Screw) – smaller than standard E26 base. Confirm your fixture uses E11 lampholders.

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

Before ordering, confirm:

• ANSI code – ESM: Verify your fixture specifies ANSI ESM or equivalent.
• Voltage – 120V: Verify fixture and supply circuit are 120V.
• Base type – E11: Physically inspect your existing lamp or fixture lampholder to confirm E11 base.
• Physical dimensions: Verify your fixture accepts a T4 bulb with 3.16-inch overall length and 0.5-inch diameter.
• Fixture wattage rating: Ensure fixture is rated for at least 250W.
• Burn position: Consult your fixture documentation for approved lamp orientation (not specified by manufacturer).

Safety & Handling Notes

• High pressure warning – face shield required: Quartzline halogen 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: Observe the rated burn position as specified by your fixture manufacturer (not provided – consult fixture documentation).
• 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.
