I have four NOS GE M400R2s that I'm considering selling. I got 8 recently and only really want to keep 4. (I don't hardly have room to keep them all!) They are 250/400w 120/208/240/277V dual-wattage quadtap ballasts. They have semi-cutoff refractors. I was thinking of selling them for like $50 each plus shipping. Let me know if any of you are interested. See pictures
here.
