This is a universal quartz halogen light head with new double aspheric lenses and zoom focus. It is a 150 watt spot light with a 120 volt dimmer and cable.

The optical system of the Dedolight surpasses the traditional concept of studio lights with fresnel lenses. The Dedolight optical system employs two lenses - neither of which is a fresnel. The second lens pre-collects the light, directing it to the front lens and minimizing light loss. This produces unprecedented focusing range and light efficiency, especially in the spot position.

Ultra compact size; Light output equal to much larger light sources.

Project background patterns with optional projection attachment and lenses.

Clean beam - no stray light; very even light distribution.

Variety of power options - Worldwide AC 100V to 255V, batteries, automotive power, or small generators.
