The 150W/230V DLH4-300 Tungsten DMX Light Head from Dedolight is a 6.9 x 6.7 x 5.2" light source that employs aspheric lens technology to achieve an impressive 4.5 to 48-degree beam spread that's especially valuable for long-throw work. The DLH4-300 has a built-in power supply and uses a special, separately purchased, 3200K black-topped 150W/24V lamp that centers the light source and provides formidable evenness in output. The fixture is also dimmable, and while you can make light intensity adjustments locally on the fixture, you can also make them remotely from a console via onboard DMX.
Dedolight offers an expansive range of accessories for the DLH-300. The Imager optical projection attachment offers optional, interchangeable 60, 85, 185, 120, and 150mm lenses for various projection distances. The device can be focused from a soft spot to a hard-edged optical spot. Framing shutter blades are also available as is an iris to select the size of the circle. There are also barndoors, gobo holders, and more.
