Yongnuo YN10800 & YN900C Bi-Color LED Panels (with a bunch of NP-F Sony-style rechargeable batteries) usually adapted to various circa 1980s Photoflex Lightdomes/Softboxes (#293 my favorite) mounted on even older Lowel light stands. Never need AC outlets and the softboxes relatively easy to set up and take down. Also using them now more and more to shoot video. Replaced my Dynalight system which too many times had to also lug along a Honda generator.
