Replacement for U-3900H HALOGEN HITACHI Halogen - T3.5 Shape GZ6.35 Base 50W 12V with Clear Finish

This halogen lamp is a compatible replacement for the U-3900H HALOGEN by HITACHI. It operates at 50W, 12V, T3.5 form factor and fits directly into fixtures that accept a GZ6.35 bi-pin base. With a rated output of 1,400 lumens, it delivers the brightness needed for clinical chemistry and laboratory instruments.

This lamp provides the stable, continuous-spectrum output that photometric and spectrophotometric measurements require for accurate, repeatable results. Its halogen gas fill keeps the tungsten filament operating cleanly, preventing envelope darkening that would introduce measurement drift over time. It supports the around-the-clock uptime that hospital and reference laboratories depend on.
