Numbers make Hilldweller's head hurt...
Markers are at 25yards L/R, 50 yards L/R, 75 yards L/R
Jeep is on the right side of a 2-lane road; camera on hood in front of driver. Reading are taken at 12" height from road surface --- this is an important stat since the LUX number could be higher at different heights. But, for consistency, the 12" number should be used to compare to other lights previously tested.
Ambient illumination from stars less than 1 LUX
Lights are aimed with about a 2" drop at 25 feet --- the lowbeams need to be aimed higher than many other types of lights due to the sharp cut-off and lack of ECE "uptick" for road signs.
