Equipped with a fixed 8.5" reflector. Accepts snoots, diffusers, gel holders, barndoors, and umbrellas for versatile light control. As an added plus for portrait work, instead of utilizing one bright modeling lamp, the M90s use three 25W lamps. This allows the models to look into the light without squinting and helps cut down on the amount of heat on the set. A power supply for this flash head is required.
