The Powerhouse Convertible ballast is designed to handle either halide or sodium bulbs - each option has seperate wire leads. Bulb choice is determined with the flip of a switch. Save the cost of using 2 differents ballasts - one during the growing stage, then another for the blooming/fruiting stage. The Powerhouse Convertible does both!
