You need to read the specs for the specifical lamp your TV is using.
Most rear projection lamps have a half-brightness life of about 1000-1500 hours (some can go up to 2500 hours).
Divide hours by how many hours you watch TV per day and you will have a pretty good estimate.
Turning on/off the lamp shortens its life as well, so don’t just turn the TV off for 5-10 minutes
About 2-3 years depending on how much you watch it.
on average about 3 years somtimes less
UHP lamps come in different wattages, so there really is not one UHP. Generally speaking, most of the UHP lamps are rated at 2,000 hours. see ref
