This Dedolight DLH4 150W Spotlight with DT24-1 is a universal quartz halogen light head with new double aspheric lenses and zoom focus, and comes with a 120V 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, minimizing light loss. This produces focusing range and light efficiency, especially in the spot position.
