The focusable, i-light & id-lights are great DC powered location choices.
By the way, they also make great broadcast camera-top lights.
They use rugged long-life lamps, & the accessories of the Pro-light. They provide essential key or fill light, eye-light, and contrast control in news and documentary shooting, without overwhelming available light.
Choose the dimmable id-light or the non-dimmable i-light, both fitted with a high intensity reflector & Prismatic Glass to give an even flood & uniform spot, and a full range of light control & mounting accessories to bring convenience & dependability to places where AC dares not go.
