This Dedolight 4-Light Kit is based on the DLH4 light head. 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 300 watt Fresnel studio fixture. In the spot position, it equals or exceeds a 1000 watt Fresnel studio fixture. The inexpensive, specially designed lamps provide precision beam aim, coupled with long life expectancy. The kit also includes stands, barndoors, bulbs, clamp, flexible stand extension and accessory box.
