Product Overview
The GE 33934 EKB Quartzline Halogen Lamp is a 420-watt, 120-volt SSTV lamp delivering 11,000 initial lumens at 3200K with CRI 100. It features a GY9.5 oriented medium two-pin base and a G7 clear bulb, making it suitable for film, broadcast, photography, and photoflood applications requiring high output and accurate studio white color temperature.
The CC6 filament provides intense, stable light output optimized for high-intensity applications. With a compact envelope (2.5-inch MOL, 0.87-inch diameter) and the ability to operate in any burn position, this lamp offers flexible installation options for professional lighting fixtures. The 75-hour rated life is optimized for applications where maximum brightness per watt is prioritized over extended life – ideal for high-intensity photography and short-duration production lighting.

Compatibility & Replacement
Fixture type: This ANSI EKB lamp fits professional film, broadcast, and photography fixtures designed for a GY9.5 oriented medium two-pin base and 420W/120V halogen lamps. Common in photoflood lights, broadcast fresnels, and specialty production luminaires.
Base: GY9.5 – an oriented medium two-pin base with a keying feature that ensures proper alignment in the fixture. This is similar to G9.5 but with orientation specific to certain fixtures. Confirm your fixture uses GY9.5 lampholders.
Ballast: No ballast required – operates directly on 120V mains power.
Before ordering, confirm:
- ANSI code – EKB: Verify your fixture specifies ANSI EKB or equivalent 420W/120V GY9.5 halogen lamp.
- Voltage – 120V: Verify fixture and supply circuit are 120V.
- Base type – GY9.5: Confirm your fixture uses GY9.5 oriented medium two-pin lampholders (not standard G9.5).
- Physical dimensions: Verify your fixture accepts a G7 bulb with 2.5-inch overall length and 0.87-inch diameter.
- Fixture wattage rating: Ensure fixture is rated for at least 420W.
- Burn position – any position: This lamp works in any orientation, but always follow fixture manufacturer guidelines.

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 – any position: This lamp is rated for any orientation, but always follow your fixture manufacturer's guidelines.
- Short rated life – 75 hours: This lamp is designed for high-output applications where maximum brightness is prioritized over long life. Plan maintenance accordingly.
- 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.
