Rob, I'm probably being dense but I don't follow the math. Then again I was never really good at math. what is the ^6? Elevated to the 6th power? So is this bulb going to last a while? That's right. P.S.: If it blows in my lifetime I'm not replacing it again. The only reason I did so the first time was because the original had blown its glass envelope (I _don't_ know why). Yikes!! |
