Calculation of light output from opal fittings
Methods for calculating light output of enclosed or reflecting fittings; formulas derived from Ryde and Cooper's work, and experimental results give satisfactory confirmation; light output of any specified fitting is shown by nomogram and comparison made between B S S 324 and German specification DIN 5036.
