MP450/C/BU/PS is the Metal Halide Bulb in the 400W, 4000K configuration. 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; keep those requirements aligned with the installed fixture. The E39 lamp base is the physical interface for this model. Choose 4000K when that colour matches neighbouring lights in the existing installation; this choice does not by itself establish the required brightness. The sales unit for this model is a pack of 12.
Buying tip: Check the existing socket for the E39 base and compare the available clearance with the lamp dimensions.
