    how do you measure the efficiancy of an LEd light from source to surface For example if I have a 1,000 lumen light and 10 luxes reach the surface 10 feet away.

    I got my cigar and I smoked it.



    Reading the discussion between you two has been quite helpful, I appreciate you both posting the technical debate, google has taken keen notice of it too. Extra kudos for both getting, AND smoking, your cigar, classic quote, I'm going to re-use that
    someday. :)
