Replying to Lights for Urban

So my friends and I started shooting some urban last year, we realized our biggest problem was lighting. Our rig is currently 15 flashlights taped together... it works better than you'd think haha. I know there are lights you can attach to your camera, and lights you can post into the ground (not sure of the terminology). Anyway, are there certain LED lights on the cheaper side that you guys would recommend for shooting urban at night? thanks!
