The Metal Halide Bulb, model MS400/BU/PS, is specified at 400W, 4000K. For an HID relamping project, this model retains the specified discharge-lamp format. Match the fixture’s lamp and ballast requirements before comparing other light sources. This listing identifies the version as pulse-start, universal-burning; keep those requirements aligned with the installed fixture.
The E39 lamp base is the physical interface for this model. The 4000K white tone is a practical option for the existing installation where an intermediate colour appearance is preferred over very warm or daylight-toned lighting. This model is sold here as a 12-unit pack.
