Features

1. Socket Cup: Die-cast aluminum effectively dissipates heat and assures

lamps maintain proper optical alignment to reflector. Snaps onto reflector
neck for easy tool-less installation. Tool-less adjustable inside or outside fix­ture to accommodate three different lamp sizes. Medium base porcelain
socket with nickel plated screw shell wired and No 18 SF1 leads to J-Box.
