The ‘e’ in ‘e-series’ stands for external control. These fixtures can be controlled centrally by a Gavita Master controller. This replaces the often cumbersome installation with contactors and clocks, and adds safety features such as automatic dimming of your lights at high temperatures and even a safety shutdown. We were the first to launch a double ended 1000W HPS lamp in this market, and we were also the first to introduce a double ended 750W HPS lamp. This lamp bridges the gap between a 600W single ended, and a 1000W double ended fixture.
