I have a 48" Hamilton fixture for sale. The fixture is in good condition and includes two 4" fans, 2 mogul sockets and T12 sockets for 2 flourescent bulbs installed. I'm asking $225 OBO for the fixture and two 175w MH F-can ballasts (there's no ballast for the flourscents).

PS. A NO output flourescent ballast can be picked up at HD or Lowes for less than $10 while a VHO ballast can be ordered from Hellolights for around $35.
