Sorry to post right away, I searched the forums with no luck. I own a DG747 (not 747L which is the newer version). I have looked online and everything seems to be pointing to this as the correct bulb: Amazon.com: Bulb for idglax ,lamp for Digital Galaxy DG-V737/DG-737/DG-747/DG-757 Video projector: Electronics However I have opened top of projector and viewed the bulb and unless that picture on amazon is not depicting the bulb itself, and just the fixture or something, it doesn't look right. The bulb inside looks more like this: http://i01.i.aliimg.com/wsphoto/v0/...LCD-b-font-font-b-Projector-b-font-font-b.jpg, it is a bright halogen bulb that is installed behind a larger domed glass casing. If someone could help clarify I would appreciate it so much! Haven't gotten any helpful answers from the company, but the amazon link seems totally correct, I just don't understand why I don't even see a bulb in the picture. Thank you so much for your time!
