So with a 245.00 bulb, and if we use 4000 hours of use as an example the cost per hour comes to roughly 16 hours of use per dollar. I actually had less than that on my original bulb around 3600 and I used eco, I know some have posted longer times, just didn't happen for me.
So right now I'm at approx 1550 hours and I paid 43.00 about 8 months ago (that same bulb is 54.00 now) so I'm at roughly 36 hours of use per dollar so far. I would need at least 700 hours based on 4k hours use to break even. I bought a replacement bulb when I ordered my projector back in 2015 and this was before I really did any research on genuine vs generic and I paid around 165.00 for it and I wished I had just waited, but too late now. I used it for about a month and then pulled it for the Maxi cheap replacement to see if it would work. I wrote the hours on it and stuck it back in the box. I don't know if that bulb was genuine or not, I think it had the Osram logo or whatever it was, I forget. But I never noticed any difference in quality or brightness, granted I have this in basement with walls painted black and usually don't have much ambient lighting but I didn't before either. Only difference is I paid 122.00 more for the first bulb and it may actually be a knock-off too.
Yes, it's a low-cost projector, I could see paying more for the bulbs if it were a $10k or a $5k PJ, but it's not. It wouldn't surprise me if the 245.00 bulb you're ordering is indeed a knock off too, they're all made in China.
