The revolutionary new Gavita CT 1930e is the first and only LED that is a direct replacement for HPS. With a footprint designed to fit seamlessly in existing HPS layouts, the CT 1930e is a highly energy efficient LED delivering serious growing power. It’s designed to be the true 1:1 replacement for the fixture that helped revolutionize the industry nearly three decades ago, the Gavita Pro 1000e DE HPS. Compatibility with wiring and electrical requirements for most indoor growing environments means this compact toplight is able to dramatically limit the cost and downtime required to convert facilities of every size. The CT 1930e delivers more crop-loving light in a broader spectrum at up to 20% energy savings than Gavita 1000 W DE HPS fixtures (based on average wattage of each fixture). Compatible with Gavita EL Master Controllers (sold separately) and most building automation systems. Patent-pending controller technology embedded within each fixture enables control of up to 2,000 fixtures per EL Master control channel and helps maintain unwavering output from light to light.
