>EL= RL * ( RV / AV )^13.1 >Now plug in 100 volts for AV. The life of the bulb soars to 8172 hours.
I ran into this formula many years ago and was initially excited by the result. But it was one of a pair of formulas, the second formula gave the lumens of light produced vs voltage. When I tried that equation I discovered that the light output declined rapidly too. A long-lasting light bulb that produced almost no light was not too exciting. ************************************************************************ * ==> QUICK LIST-COMMAND REFERENCE - Put the following commands in <== * ==> the body of an email & send 'em to: [EMAIL PROTECTED] <== * Join the list: SUBSCRIBE COMPUTERGUYS-L Your Name * Too much mail?
