The standard of rental studios worldwide, Profoto offers action-stopping short flash duration and fast recycling times for any type of application.

Heavy-duty design, self seeking voltage, consistency of light output and color temperature, and compatibility with a full line of modular light shaping tools, make the Pro 7 power packs the first choice of photographers around the world.
