TESTS OF WALLACE AND TIERNAN FA-240 RANGE LIGHT

The shape and intensity of the beam emitted from the FA-240 Range Light with different lenses and 12-volt lamps were investigated. The report concludes that the flatlite lens should not be used with a 12-volt lamp and that the advertised intensity values for the range light are overrated. (Author)
