Alright I tore apart my hood and found it is using a Robertson S40BP ballast. The ballast says it is for use with one 30,32, or 40watt bulb. Now the bulb originally being used was a GE 40watt T12. Online ive found that this ballast will support 1 F30T8, F30T12, F40T12, FC12T9, or FC16T9. The hood is 48" long. Now if I'm reading this correctly will I be able to place an Aqua-Glo 40watt T8 in the ballast without any problems? Im unsure so im asking first. The old T12 in the hood is already black on one end so its a matter of time until it dies on me so I just want to make sure I get a compatible replacement bulb.
