The Gavita EL2 Master Controller represents a huge step forward for indoor lighting systems. Now you can replace your contactor / timer set-up by communicating with your ballasts directly via controller cables. The Master Controller system switches up to 80 ballasts from a central point and comes with an easy-to use interface and a clear display. You can even split the 80 ballasts between two rooms in alternating 12/12 cycles. If this wasn’t enough, the EL2 comes with a host of features that will increase safety, eliminate inrush current and lower the chances of experiencing botrytis (rot).
