Product Overview
The 88623 is a GE Quartzline® tungsten halogen lamp from GE's Stage and Studio line, built for 3200K color-consistent output over a 500-hour rated life. It uses a T-8 quartz envelope with a G38 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. This item was renumbered from GE product 39587 to 88623; both numbers refer to the same lamp.
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 (G38) 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 (BDTH) matches your fixture's mounting orientation.
- This lamp was formerly sold under GE product code 39587 — confirm you are ordering current stock under 88623 (BWA-Q2000/4CL/BP).
- Filament with low noise construction.
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.
- Burn base-down-to-horizontal (BDTH), but avoid horizontal burning with a support spine beneath the filament to prevent premature arcing.
Compliance
- Dispose of/recycle per federal, state, and local regulations for lamp components.
- ANSI code BWA — confirm ballast/transformer compatibility before installation.
- UL Standard 1572 enclosed-fixture rating applies where noted (see Before Ordering).
