Flip Flop Relay

Newbie here looking for a Flip Flop Relay thats actually cheaper then a 600W HPS ballast.

Anyone have any links to a cheap Flip Flop Relay?


( A Flip FLop Relay is used to alternate the output of one 24 Hr a day Ballast to two 12 Hr a day Lamp and Hoods. It's used when the two lamps are in opposite light cycles)

cant you just buy 2 timers or check out hydrofarm catalog

all you need is a relay,you have to attach the 12/12 timer to the "signal pins" and the "switching pins" switches between the ballast and 2 600w lamps. don't know the details, i haven't made it yet search it and you'll definitely find something.
