Fan, detached18' head cable. The Dynalite MH2050 Roadmax Flash Head is a fan cooled, economical, minimum weight head with a 2000 watt/second flash tube. It has a built-in recessed reflector with 140° coverage with no hot spot for even light dispersion. Other reflectors can be added if desired for different degrees of coverage.The MH2050 has many of the same specifications as the 2040, which it replaces. Improvements include lighter weight, slightly smaller size, and a direct-plug method for the head-to-pack cable. The elimination of the pigtail ensures a better connection to the power pack, and it saves space when you pack the head away in your location case.A power supply for this flash head is required.
