Great link. Just skimming that document you can see Richardson's style shine. (literally, shine.) So bold.
Another example of his signature "hot spot" on last year's Jeter commercial he shot.

Par cans take par64 globes. They come in flood, medium and spot (also VNSP, very narrow spot if memory recalls). You change the bulb to change the beam angle. Lights with multiple banks of bulbs arranged in a grid are generally called maxi brutes.

What is the best way to make this daylight balanced instead of incandescent
Most Parcans use PAR64 globes, you have to swap the whole globe out to get wide, medium, spot, and narrow spot, etc. configurations. Of course there are smaller Parcans that use globes like PAR36, etc.

Usually there is no switch in line, it just comes on when you plug it in. It's pretty basic wiring like any light bulb, but obviously something is wrong either in the wiring, the power cord, the connections, or the bulb.
I'd see if you can find an electrician to take a look, or take it to a lighting rental house and see if they can help you.
