I have a 'shop light' and ballast meant to run two 4' florescent tubes - either 2 x 40w T-12 (48") or 2 x 32w T-8 (48").
I'd like to take it apart to run 2 x 24" 20w T-8 bulbs for an aquarium.
Q - could I simply shorten the 48" to 24" and run the 20w bulbs with this ballast? Or, would it burn out the bulbs? (or burn down the house?)
Q - if that would not work, could I instead run the lights in series; ie 2x 20w 24" giving me 40w - which would be the same as the 48" T-12, only made up with a 24" + 24" in T-8?
Thanks
