This halogen lamp is a compatible replacement for the 1130ZH LOWER by VANGUARD. It operates at 15W, 6V, T3 form factor and fits directly into fixtures that accept a G4 bi-pin base. It is designed to restore full performance in laboratory, medical, or precision optical instrument applications.
This lamp provides the stable, continuous-spectrum output that analytical instruments like spectrophotometers and photometers require for accurate, repeatable measurements. Its halogen gas fill keeps the tungsten filament operating cleanly, preventing envelope darkening that would introduce drift in optical readings. It helps maintain consistent results across calibration cycles.
Key Features & Benefits
