I bought this projector a couple of months after it came out and i'm still on the original bulb! It's our primary, well our only TV. We have kids so they watch their shows on it as well as the wife and I in the evenings. I've had to reset the hours on it twice.
I run it in eco mode all the time. Currently over 6000 hours on the original bulb. I bought a replacement 2 years ago for superbowl just in case it went out and have never had to install it.
