Yes, you must have a ballast to fire a MH lamp, or fluorescent bulb. The ballast is what limits the current in the circuit. Basically, it powers your lights, without a ballast-you have nothing.
Here are my three, top is an IceCap 660 for my actinics, and the bottom two are each IceCap electronic 250 watt MH ballasts.

Keep in mind that ballasts aren't usually all open like Hurt's ballasts, with the wires exposed like that. His picture is a DIY solution, but it does illustrate clearly the different types of ballasts out there.
You can buy commercially made ballasts where everything is enclosed in a metal box with connectors for your power cord and lights.
