Just found a source for 3 Light socket cluster with 6" wire attached. Cost is $2.25 each. Using 9 equals 27 bulbs; 23W CFL mentioned above for $.50 each. That means cost will be 9 x $2.25 (3 light cluster) $20.25 + $13.50 (lights) + 15.03 (wiring & plugs) = $48.75 total for lights, sockets, and wiring and I'll get 43,200 lumen!
