Product Overview

The 33934 is a GE Quartzline® tungsten halogen lamp from GE's Stage and Studio line, built for 3200K color-consistent output over a 75-hour rated life. It uses a G-7 quartz envelope with a GY9.5 base rated for 120V operation.

Quartz halogen lamps are designed to be operated within close voltage tolerances; excessive voltage can drastically shorten life even as it raises light output. GE recommends contact pins be kept clean, since oxidation above 350°C can cause arcing and irreparable damage to both lamp and lampholder.

Compatible Applications

Studio and broadcast lighting fixtures
Stage and theatrical lighting instruments
Followspots and profile/Fresnel fixtures rated for this wattage and base
Retrofit replacement in fixtures originally specified for this order code

Before Ordering – Verify

Confirm the base type (GY9.5) and voltage (120V) match your fixture before ordering.
Do not exceed 110% of rated voltage; overvoltaging shortens life and raises seal temperature.
Confirm burning position (ANYCH) matches your fixture's mounting orientation.

Safety and Handling Guidelines

Turn power off before inspection, installation, or removal — risk of electrical shock.
Keep combustible materials away from the lamp and use only in a fixture rated for this product — risk of fire.
Pressurized lamp: unexpected rupture may cause injury, fire, or property damage. Use eye protection and do not touch the glass with bare hands.
Do not use the lamp if the outer glass is scratched or broken; operate only in the specified position; do not exceed 110% of rated voltage.
Allow the lamp/fixture to cool before handling; turn power off before installing the lamp; dispose of a broken lamp in a closed container.

Compliance

Dispose of/recycle per federal, state, and local regulations for lamp components.
ANSI code EKB — confirm ballast/transformer compatibility before installation.
UL Standard 1572 enclosed-fixture rating applies where noted (see Before Ordering).
