The EL3 enables you to set sunrise/sunset dimming, high-temperature dimming, and high-temperature shut-off for all connected fixtures. Best of all, the EL3 lets you build and program entire schedules for your growing cycles. When using a compatible Gavita or Sun System LED fixture, you will be able to view at the individual fixture level, how each one is performing.
