Q & A
What ballast do I use for this fixture ? Each fixture has two bulbs

Mark @swimwear

Here are 4 potential ballasts that should work with these bulbs. Depends on the voltage you are looking for. 120, 277 or multi-tap. http://www.bulbs.com/T12_Lamps-Fluorescent_Ballasts_--_U--Bent-Ballasts-Category/2-Number_of_Lamps/2_x_40W_--_44W/results.aspx
