Metal Halide Bulb (MP450/BU/PS) is the 400W / 4000K version. Use this model when servicing a compatible HID fitting whose ballast is rated for this exact lamp type and power. 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. For the existing installation, 4000K offers a white-light appearance between warmer residential tones and cooler daylight colours. This model is sold here as a 12-unit pack.
Buying tip: Check the existing socket for the E39 base and compare the available clearance with the lamp dimensions.
