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!! |

That's right. Awesome! I like the sound of that!! :-) Thanks. I assumed that if since it was rated for 15 hours that it would last for 30 hours if run at approx half the rated volts. -- Sven Weil New York City, U.S.A. |
