Is this a hoax?? I thought candlePOWER was an expression of a RATE of energy (luminous energy put out by a light source) while photons were little packets of energy. It would be possible to express candlepower in photons per unit time, but not in photons alone. And this would depend on the wavelength(s) in the light. -- ------------------------------- Disclaimer: The views contained herein are | dan levy | yvel nad | my own and are not at all those of my em- | an engihacker @ | ployer or the administrator of any computer | at&t computer systems division | upon which I may hack. | skokie, illinois | -------------------------------- Path: ..!ihnp4!ttrdc!levy
