There are two common types of reflector cords used on HID grow lighting fixtures, "standard" and the proprietary "Hydrofarm" type. The two plug types are not compatible unless an adapter is used. If you are purchasing a new ballast or reflector, be sure to review what plug type each uses so you can ensure fitment.
If you have a ballast of one plug type and a reflector of the other, adapters are available at Hydrobuilder.com. You should not lose any performance by using an adapter and they are a simple way to solve this issue at about $10. View all of the reflector cord adapters here.
Solis Tek has created a digital splitter to allow one 1000 watt ballast to have two outputs and control two lower wattage lights for more even coverage or full spectrum coverage.
