FulhamWorkHorse Adaptable Ballast, WH2-120-C (2 Pack)

Compact and is the only product that support LPS lamp, wires extending from ballast makes it convenient to wire up and less joints so very safe and no arcking

Need to replace ballasts in old bathroom fixtures. They work better than the original and were delivered in a couple of days!

I bought this ballast to replace an existing one which had 4 wires. This one is the exact same part number with only three wires. Could not use it. I need four wire prongs to plug into the round fluorescent bulb.
