Product Overview
The 88622 is a GE Quartzline® tungsten halogen lamp from GE's Stage and Studio line, built for 3200K color-consistent output over a 250-hour rated life. It uses a T-7 quartz envelope with a G22 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 39191 to 88622; both numbers refer to the same lamp.
Compatible Applications

- 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 39191 — confirm you are ordering current stock under 88622 (EGT-Q1000T7/4CL).
- Filament with low noise construction.
