Projector means it uses a lens in front of the bulb. This can be Xenon or Halogen, usually xenon.
Reflector is the old kind, and is usually halogen. Xenon bulbs in these don't work well and tend to blind other drivers.

Bi-xenon means it has high and low beams. This uses a shade that moves down when you want high beams.
Non bi-xenon lights will have halogen high beams in separate reflectors.
