General Procedure Choose Average BEFs for Magnetic Ballasts Choose BF and Calculate Watts Input Normalize Watts to a 95% BF

For a 2F40 T12/ES Ballast Case (1) Start at BF = 95% Case (2) Start at BF = 88% (1) 'Average BEF = 1.24 at BF = 95 W = 95/1.24 = 76.6 W
(2) Average BEF = 1.24 at B F = 88 W = 88/1.24 = 71.0 

# W aliz ed Inp ut Watts = (95188)* 71 = 76.6 Watts
