Gavita CT 1930e LED Light - 120-277V

Replace HPS Lighting with the Gavita CT 1930e, 120-277V

The Gavita CT 1930e is a professional commercial LED grow light engineered as a direct replacement for legacy high-pressure sodium systems in commercial indoor cultivation facilities. Operating on 120-277V AC and drawing roughly 780W -- about 22% less than the 1000W double-ended HPS fixture it typically replaces -- the CT 1930e combines Gavita's full-spectrum output with IP66 ingress protection and the reliability commercial operators expect from the Gavita brand. Purpose-built for growers ready to transition from HPS to LED without compromising yield or crop quality.

Key Features & Benefits

• Direct HPS Replacement Performance: Engineered to match or exceed the crop performance of equivalent HPS systems, enabling a transition from HPS to LED without new grow protocols for most crops.
• Lower Power Draw Than 1000W DE HPS: Drawing roughly 780W versus the 1000W draw of the double-ended HPS it replaces, the CT 1930e delivers measurable electricity cost reductions from the first crop cycle after installation.
• IP66 Ingress Protection: Fully sealed against dust and high-pressure water jets, the CT 1930e withstands the wet cleaning and high-humidity conditions standard in professional grow facilities.
• 120-277V Wide-Range Input: Operates on standard single-phase voltages across the full 120-277V range, making the CT 1930e straightforward to deploy in existing and new-build facilities.
• Full-Spectrum Output: Covers the complete photosynthetically active radiation band to support productive crop development across vegetative and reproductive growth stages.
• Integrated Driver: No external ballast or driver unit is needed, simplifying installation and reducing the number of components requiring maintenance.

Who Should Use This

Commercial greenhouse and indoor cultivation operators currently running HPS systems who want to reduce energy consumption, improve light spectrum quality, and benefit from LED longevity without disrupting established growing practices.

Compatibility

The CT 1930e operates on 120-277V AC and is compatible with Gavita's EL3 master controller for centralized dimming and management. Power cords, dummy plugs, and interconnect cables for the CT 1930e are sold separately. Verify facility circuit load capacity and hanging hardware compatibility before installation.

Frequently Asked Questions

How much less power does the CT 1930e draw than the HPS it replaces?

The CT 1930e draws approximately 780W, compared with the 1000W draw of a typical double-ended HPS fixture it replaces -- roughly 22% less power for comparable canopy output. The LED technology converts electricity to usable photons more efficiently than HPS, which wastes a significant share of energy as infrared heat.

Can the CT 1930e be used as a direct replacement for double-ended HPS fixtures?

Yes -- the CT 1930e is designed as a direct replacement for commercial HPS systems, including DE configurations, with hanging and electrical connection points positioned to simplify fixture-for-fixture swaps in existing grow room infrastructure. Most facilities can swap fixtures without redesigning their mounting layout.

What accessories are needed to operate the CT 1930e?

The CT 1930e requires a compatible power cord, sold separately in 120V, 208-240V, and 277-400V variants, appropriate hanging hardware, and optionally a Gavita EL3 master controller for dimming and zone management. Dummy plugs are also available for unused connection ports.

Does the CT 1930e require a separate driver or ballast?

No -- the CT 1930e has an integrated driver, so no external ballast or driver unit is needed. This simplifies installation compared with separate-driver LED systems and reduces the number of components requiring maintenance.
