The OLD STYLE 1X65W replacement ballast for Coralife Aqualight Fixtures will run one 65W compact fluorescent lamp. Though the ballast does include the straight pin connector and the quick disconnect, because the wires will be too short in some situations you may have to cut the wires and re-connect the wires with wire nuts to install the ballast. You will need to open up your fixture and look at the ballast to see if this matches the ballast in your Coralife fixture. The 1X65W ballast this replaces has Model: BH-APL0551A written on it.
