Metal Halide Bulb (MS400/V/ED28/PS) is the 400W / 4000K version. This model is a maintenance lamp for an existing HID luminaire using the matching lamp system. Choose it by the ballast lamp designation and base, not by wattage alone. This listing identifies the version as pulse-start; keep those requirements aligned with the installed fixture.
The E39 lamp base is the physical interface for this model. Where the existing installation is specified at 4000K, this version keeps the replacement within the same colour family. Allow for 12 units per pack when ordering this model.
Buying tip: Check the existing socket for the E39 base and compare the available clearance with the lamp dimensions.
