	Subject - unit amperage David Hyatt http://www.lithonia.com/Library/IESFiles/IESViewer.asp?FileName=Lithonia_LightingFluorescentLensed_TroffersGt8LTL7425.ies Section 220.4B says you have to use the amp rating of the unit not the wattage of lamps. What is the amp rating of this light? wareagle David The input amperage to the Fluorescent Troffers include the ballast losses. It is slightly higher that the wattage of the bulbs. David Hyatt I agree, but is there a way to get an exact figure? JimmyDee Only way I know of is to read it off from the ballast. Jim
