when filming on location without outlets, what would be a good alternative lighting source?
50W LED floods which can be run from car batteries/inverter. 12v worklights are an option too.
Generator?
For very cheap, you can get battery-powered LED panels (linkage) in varying sizes and mounting options. Many have a camera-shoe attachment as well as a 1/4" 20-thread hole to screw onto the top of lightstands.
They come in all shapes & sizes, and last quite a long long time. Obviously, keep a large stack of extra AA's on hand.
Bounceboards are always needed, regardless of where you are. They can be grabbed off the shelf for about $5.00 at Home Depot or similar, for a 2" x 4" foam board - white on one side, and silver reflector on the other. Found in the insulation section.
Do some math & make sure you're not going to drain your car battery fast with what you plug in. You can get deep-cycle batteries that might be more suitable, but if you're prepared to lug around a rack of those you'd probably just be better off with a small genny anyway.

i've been thinking about that but i'm afraid the noise from it (if it's gas powered) will be too much for the sound gear plus they might not allow those on the streets for filming, battery powered is an option due to its small size and quietness but those run about 5,000 to 10,000 a pop. i'm just worried that a led clip light won't be powerful enough out in the sunlight.
i certainly have enough manpower.
