Frezzi's award winning lighthead, the Mini Fill, was originally designed by Frezzolini for the first Mount Everest climb. It has continuously been updated and improved for the needs of the broadcasting community. The Mini-Fill's reliability, performance, and portability has established its international reputation and inspired an entire line of lighting products available today. Previously known only to the broadcasting community, this exceptional lighthead has become the light of choice for the professional videographer and are available in both standard (on/off) and dimmer control models. The Dimmer Mini-Fill provides the ultimate in flexibility for camera top quartz-tungsten lighting. An advanced pulse width modulation circuit allows instant adjustment of the light intensity while minimizing color change and conserving power. Adjusting the light output is as simple as turning the dial on the back of the unit.
