The DLH4 light head forms the core of the Dedolight Master 3-Light Kit. It's extremely compact, yet (with its dual-lens concept) provides high light output. With a 150W lamp in the flood position, its light output is greater than a 300W Fresnel studio fixture. In the spot position, it equals or exceeds a 1000W Fresnel studio fixture. The inexpensive, specially designed lamps provide precision beam aim, coupled with long life expectancy. Each light head is equipped with a power supply/control unit, and a 150W lamp at a nominal voltage of 24V. Its AC power input is set for 117 AC voltage. Also included are stands, barndoors, bulbs, clamp, flexible stand extension, accessory box, clamps, wall holder, and a hard, compartment divided case.
