MH400/U/ED28 is the Metal Halide Bulb in the 400W, 4000K configuration. This model can keep a matching HID installation in service without treating a similar-looking lamp as electrically interchangeable. 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.
