At the heart of this Dedolight Standard HMI 400 watt 1 light kit is the DLH400D – a 400 – 575 watt daylight fixture for single ended HMI lamps. Used in conjunction with the Dedolight DEB400D electronic ballast, the 400D brings the same level of superior, sophisticated performance to the world of HMI, as the 436 and 650 provide for tungsten.

The head is powered by the DEB400D electronic, flicker free ballast. It has automatic input adjustment from 90 – 260 volts AC and dual power adjustment from 400 to 575 watts. It is dimmable to 40% of full power. Its active power factor correction assures constant Kelvin temperature throughout dimming range, and with different line current voltage.
