Thanks for the link Paul, I was trying to recall the definition of candela on my way to work today.

I remembered the steradian part but couldn't dredge up the 1/683 Watts.

The inclusion of 555 nm in the definition is a bit strange though.

It works fine for black body radiation, but technically a 632 nm HENE laser would always have zero candlepower no matter how bright the beam is!
