>For the film 'Monster' we put a china-ball on the end of a poll on the dolly during the skating rink scene. We used a 4D size battery (very large boat or truck battery) and an inverter with a paper lantern and a 500w globe (probably an ECT). If you need to hand-hold the paper lantern, such as in a 'walk and talk' situation, and can't have any cable to the light, I find it best to use a Jem-Ball with a 200watt or 400watt Joker-Bug, slimverter, and battery belt, all slid into a backpack. The Joker-Bug usually has a CTO glass if you need to be tungsten balanced, and bobinette is usually good if it's too bright. Hope that helps.
>A note about the battery: Any large auto-type battery will work, but the best is some sort of sealed gel-cell, as auto or marine batteries can be dangerous - flammable hydrogen fumes and spillable battery acid among them.
Los Angeles, CA or anywhere else I'm invited
