The code printed on your old lamp or its housing should match one of the codes listed above. Hitachi and third-party suppliers sell the same lamp under several numbers.
The model number is on a label on the base or rear of the projector, and in the on-screen menu under Information. Still unsure? Send a photo of the old lamp and we'll confirm the match.
If your projector is one of these rather than the ED-X31, the same lamp is the correct part.
