Query: Life is NOT 10,000 hours

10,000 hours = 416 days. In other words, more than a year.I bought this replacement bulb on Oct 6, 2005. Today is the first of Feb. 2006--it died. Assuming that I never turned off the lamp during those 3 months, my math tells me that in order for the bulb to burn out I must have had the lamp on for 111 hours/day for five months. (111 hours x 30 days x 3 months = 9990 hours.) Only, I never quite lived a 111 hour day yet.If I figure I used the lamp for no more than 6 hrs/day for those 3 months. I only got 540 hours out of it. However you look at it, it seems this bulb missed the mark on the 10,000 in a premature death.
