This Dedolight DLH4 150W Spotlight with DT24-1 is a universal quartz halogen light head with new double aspheric lenses and zoom focus, and it comes with a 120V dimmer.

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.
