While the Classic DLH4 is controlled from a separate ballast or power supply, the Classic DLHM4-300 has a built-in ballast with or without DMX function. The Classic DLHM4-300 (manual dimming) is among the most popular focusing dedolights and is available in rental houses across the world. With a 40-year proven track-record in the professional lighting industry, this Classic is high up on the aspheric optics family tree. The Academy Award winning design has an awesome output (6 times that of a comparable Fresnel). The optics deliver a completely homogenous clean beam with very little drop-off at its edge. There is light where you want it, and outside of that there is only shadow. It is what your favorite rental house will hand to you configured in the 3-head "Master Kit".  Built like a tank, there is still no other system in this class that compares to the performance and longevity of the Classic Dedos. 

With its built-in ballast and AC power cable, the DLHM4-300 plugs directly in a regular household outlet. The ballast converts AC to 24v to use low-voltage 24v 150w or 100w tungsten lamps.  It dims beautifully from 100% to 0%.  The manual ballast adjusts the intensity by turning a simple knob.  A DMX/Manual model is also available (DLHM4-300DMX). Running a Dedo low-voltage system increases the longevity of your lamp (4 times longer running time) and efficiency with twice the lumen output of typical studio halogens.
