L7404 Halogen Bulb - G4 Base 20W 12V

This 20W 12V halogen lamp (ANSI code L7404) is built for use in laboratory, medical, or precision optical instrument applications. It seats securely in the G4 bi-pin base for a reliable connection. The 350-lumen output supports consistent performance throughout the lamp's rated life.

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.
