Metal Halide Bulb (MS400/HOR/T15/4K) is the 400W / 4000K version. 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. The E39 lamp base is the physical interface for this model. The 4000K colour specification helps distinguish this lamp from warmer and cooler versions for the same existing installation.
Buying tip: Check the existing socket for the E39 base and compare the available clearance with the lamp dimensions.
