The DLH400D head takes single-ended 400W daylight metal halide lamps that can also be operated at 575W when used with the DEB400D flicker free ballast.
The head features a far greater 17:1 spot to flood focussing range than a standard Fresnel, and produces an exceptionally clean beam with even distribution and no stray light due to its high quality optics. The compact and quietly running ballast unit, which comes with a bracket for attachment to a stand, allows dimming from 400W down to 40% and has a boost position for operation at 575W. Four barn doors, cables, a spare lamp, and C-stand are included in the kit, along with gels if required.
