If this bulb lasts the same 2.5 years the first one did,ill be ready to move on to another tv before that anyway,assuming 4k becomes close to this affordable in large screen sizes as well in the next couple years.
These are not interchangeable like light bulbs. The lamps are specifically manufactured to match each chassis model. The voltage and current draw has to be exact to prevent the TV's computer from faulting out. That's why other lamps cause problems, especially the Chinese knockoffs.
I bought a sensor for about $100 and downloaded free calibration software to calibrate several sets owned by friends and family. There is a learning curve, but after doing it several times, you start to get good at it. Each calibration can take up to 4 hours, so it helps if you are patient and a bit of a perfectionist.

There should also be a calibration thread for your model here in the forum. It will contain tips, and instructions on how to access the calibration controls of your TV.
The lamp's properties change a lot in the first 200 hours or so, then settle down and change slowly over time, until the rapid dimming that you noticed near the end of the lamp's life. Most people calibrate every year due to this lamp aging, and 200 hours after they change lamps. I found that if I calibrate the second (and final) time near the middle of the first lamp's life, there is really no need to re-calibrate at all. When the lamp is replaced, the wow factor outweighs the slightly off calibration, which improves steadily until the lamp's mid-life, and by the time the picture is off again enough to notice, it is time to change the lamp again anyway. YMMV, etc.
