If you can look past the super-cheeeese factor in this video, it shows those lights being used in a variety of ways. All the people shots were with those lights. This video was for an internal training day for a client, the company gave us free reign to make it as silly and lighthearted as we wanted, but we had to use the company employees as talent.
The "anonymous" style shots were with two lights facing toward the subject for the edge lighting, and a third light on the background.
The "selling" shots were with two lights on the green screen behind the subject, and one light on the subject. Not ideal for lighting the subject; we've since gotten a couple more lights for better green-screen.
The "wizard" shots (that's me, by the way) were with the main light below the subject, just out of frame, lighting up from underneath. Not the "proper" way to light most subjects, but we wanted that eerie, almost ghoulish effect. The other two lights were behind the subject, just out of frame to left and right. Smoke machine was immediately behind subject's back. Green tint and particle effects were added in post.
Of course, you can use them for standard three-point lighting. We also have a longer video where we used the lights in a more standard setup for a newsdesk-style video - I can't find that one, I don't think we ever put it on Youtube. It worked pretty well for that - since we had two people at the desk, we had two equal main lights in front, and one shared hair light overhead.
