Bulb Life:
The manufacturers give two numbers: B3 and Tc. B3 indicates the minimum number of hours 97 percent of the lamps will last. After this time elapses, the frequency of failure starts to increase. By the time the Tc value is reached, 63 percent of the lamps have likely failed. Sorry if it sounds so complicated, but it is not that simple for all kinds of things due to tolerances.
