I usually can't afford to purchase new equipment unless its on sale. Video is my serious hobby, so I don't have to have equipment right away for a source of income. Over the years I have acquired multiple lights which are essentially kits that were eventually offered by the manufacturers.

Studio kit... LitePanels 1x1 Spot and Flood, ENG, 3x Manfrotto Nano stands
LitePanels Caliper Kit... original LitePanels 3x light kit, 3x Manfrotto Nano stands
LitePanels Chroma Flight Kit... 3x Chromas, 3x Manfrotto Monopods
LumeCube... 3x Panel Pro lights, 3x five foot stands

While the LitePanels Caliper and Chroma lights are capable of being powered by AA batteries, they go through them quickly and at reduced output, making them less useful for long interviews.

What finally made all of these "portable" was my acquisiton, last month, of four Anton Bauer 98 WH batteries and chargers.
