Poles, exterior fixtures, resi recess, comm recess, (HID too) canopy, & landscaping available from RUUD LIGHTING, as mentioned above.
WW Grainger has catalog, CD, and "on line pricing, once you register at there site.
I used the estimator book & software version a while back; thought the pricing was "high" for some items, and average for others.
Light fixtures (comm) best buy pricing usually comes from supply house. Find a supply house with a comm lighting guy.
I don't know where you are located, but Graybar seems to be pushing "service". They are "choosy" about opening accounts., but they do quote for cash sales quickly.
Let me know if this helps.
