I recently changed my bulb after 1300h (10 months) and I wonder if somebody got the same experience like me:
I measured the new bulb with the same equipment and settings::
original bulb with 0 hours: 400 lux
new bulb with 0 hours: 310 lux
The bulb is original form Sony Prime support. It is not the first time, that I found that the replacement bulb's are not performing as well as the brand new, which comes with the projector. I saw this behavior on Sony, JVC projects in the past.
Question: What could be the issue? Do the panels really get so fast "older" and lose light performance?
