for the clamp on scoop lights (brooder lights), do yourself a favor and get the ACDelco clamp lights. They come with longer cords and have a bolted hinge point that won't fall apart like the friction knuckles. I went through half a dozen of the standard clamp lights in my first year of shooting before I got my first ACDelco...which I'm still using 3 years later.
For the work lights, Coleman has a 500w you can get through amazon that goes up to 7' tall.
At a craft barn type of store, find white foam core in big sheets to use as soft white bounce cards...then buy shiny metallic stretchy fabric to fit the foamcore and clamp it to the board to make a silver or gold reflector...or red...green, chartruse, whatever.
There are plans out there to make your own barndoors to attach to worklights and clamp lights as well...they work like a champ (as long as you use the compression screw method of attaching rather than the pop rivet method).
