If you have a projector than you are using a projector lamp module. Inside that module is an Osram or Philips bulb.
The bulbs made by these companies are generally considered "original" bulbs. Sometimes that word is tossed around a lot to convince people they are buying a genuine original lamp module when they are not. The bulb itself is only one component of the lamp module.
