This approved method is a revision of and replacement for LM-35-89, IES Approved Method for Photometric Testing of Floodlights Using Incandescent Filament or Discharge Lamps.1 This version has been revised primarily to collect data using a single enlarged standard set of data points for all beam spreads. The floodlight is aimed horizontally on either a C-type or B-type goniometer. The report (and IESNA-file) continues to be presented in the traditional B-type format.
