Dynalite MP500 500WS Power Pack with Built-in Pocket Wizard Digital Radio Receiver Circuitry. (M500wi)

• Dynalite shooters aren't forced to lug big, fat, slow gear on location. They travel light and fast, without sacrificing a single f/stop. Dynalite is famous for beautiful light from portable, powerful packs and heads. That tradition continues in their new Roadmax Series Packs & Heads.
• Studio power that's meant to go anywhere you do. 500 or 1000 watt seconds, Roadmax packs are our top of the line units.
