Wiring new hqi MH reflector??

[jerr1827]

Hello. Just got in new hqi reflectors to replace my old pendents; the reflectors have 2 wires coming out, however the 3 prong power chords that plug into the ballast from the old pendents have 3 wires; 1 green, 1 black 1 white. How do i wire the new reflectors to the old 3 prong power chords? The ballasts are made by blueline and have the 3 prong inputs so i need to use the 3 prong power chord. Please enlighten me!

Ground the 3rd green wire to the pendants housing. Find a bolt or screw and ground there. You can ground to a screw or bolt inside the housing if you have access to it.
