I've had my PJ750 for 3 years and it's been a great projector. I've had to reset my bulb timer twice, so I know it's getting old. this is what I'm trying to find out. when purchased, the PJ750 has a lumen spec of 2200. after looking at alot of reviews here, that spec means very little. I'm trying to get an idea of what my existing lumen level would be equivalent to todays projectors. I can tell my bulb has lost alot of brightness over the years. Just trying to get an idea of what lumen level it is truly at. Any help would be appreciated..
