Maiceman, DId not know you knew mark. Either way I think (note this is once again me and my observations) that the only real difference between a 36W and a 55W and a 96W PC
bulb is its lenght.
Now there are suttle differences when it relates to the pin configs and all but overall a 36W bulb is about 18" in lenght and a 55W bulb is just under 24" and a 96W bulb is 36" long.
tyler, it sounds like your talking about a 13W PC
kit then. If thats the case then yes each ballast goes to its own bulb. I have a 2 X 13 W kit from them for when I had my 45 gal
up and running. I used 2 X 13W actinic bulbs. Back then the ballast was just a small white square with some wires comming out if it. No real diagram on it.
