Urbis Evolo lamp holder assemblies

Regarding my previous post about different Evolo optics, the adjustable plate for the lampholder is different too. The ZX3 optic (right hand lantern) lampholder is on top, and the Sapphire optic (left hand lantern) lampholder is below. The bottom one has more material between the screw holes to force the lamp to be closer to the column end of the optic than the street end.
