I frequently receive junk mail with commercial lighting products. Hi-Bay 4' four lamp F54T5 style fixtures w/lamps cost about $215 or less at wholesale prices. Also E-bay often have a few of these. I paid $40 for a four lamp new in the box F54T451 (4100K lamps) I bought 3000K for budding and 5000K for veg at about $9 per lamp.
