The E-Series LED Adapter is designed to be used with the Gavita 1650e LED fixtures. This product runs inline with the power cord to the fixture. Using this device in conjunction with the LED fixture will allow you to control them with an EL series controller. These adapters utilize cables with RJ45 connectors for daisy chaining the control signal between adapters. Please use 906715, 906716 or 906717 for communication with the EL controller. Adapters are cETLus listed as well as IP66 rated for commercial use.
