From what I've found on the web, D1S & D2S are essentially the exact same capsule, though in non-compatible mounting arrangements. There is also a D1R and D2R, which are NOT equivalent to the "S" variants. The "R"s have an opaque coating on part of the arc chamber to restrict where the light goes.
The "ballast" isn't really a "ballast" in the strictest sense. It's really the ignition module for the capsule. Attaching it directly to the capsule eliminates the need to run 20Kv wiring to fire off the capsule (like a D1S would require). Once the arc is "running", there is no longer a need for the 20Kv, and the system runs on a considerably lower voltage (85v? not sure...).
