Gavita RS 1900e LED Grow Light

Commercial-Grade LED Output with the Gavita RS 1900e

The Gavita RS 1900e is a professional-tier LED grow light delivering 1900 µmol/s of photosynthetic photon flux at 650W input power -- achieving 3.0 µmol/J efficacy -- across a full-spectrum output built for high-intensity indoor cultivation. With a 6-bar configuration, wide-range 208-480V AC input, and a compact 44.8 x 43.25 x 3.3in form factor at 29.8 lbs, the RS 1900e is engineered for large-scale commercial operations that need both strong photon output and installation flexibility.

Key Features & Benefits

• 1900 µmol/s PPF at 650W: Delivers the photon flux density needed to drive strong photosynthetic rates across dense commercial canopies, supporting productive crop cycles.
• 3.0 µmol/J Photon Efficacy: Efficient conversion of electricity to usable light reduces the energy cost per unit of light delivered compared with legacy HPS or lower-efficiency LED systems.
• 6-Bar Light Bar Configuration: The multi-bar fixture design provides wide, even light distribution across large canopy footprints, reducing hot spots and helping keep PPFD consistent edge to edge.
• 208-480V AC Wide-Range Input: Handles a broad span of facility voltages, so the fixture can be wired into diverse electrical setups without step-down transformers or custom rewiring.
• Full-Spectrum Output: Spans the photosynthetically active radiation band plus far-red wavelengths, supporting plants from early vegetative growth through finishing.
• EL3 Controller Only: Built to pair with the Gavita EL3 Master Controller for centralized dimming and scheduling; legacy EL1/EL2 controllers are not supported.

Who Should Use This

Large-scale commercial indoor cultivators, greenhouse operators, and vertical farm facilities that need strong photon output per fixture while keeping energy consumption in check. The RS 1900e suits operators replacing high-wattage HPS double-ended systems with modern LED technology.

Compatibility

Runs on 208-480V AC and pairs with the Gavita EL3 Master Controller for centralized dimming and environmental management across large fixture arrays. Hanging hardware and rail system brackets are sold separately, so confirm facility electrical supply and distribution capacity with a licensed electrician ahead of installation.

Frequently Asked Questions

How does the RS 1900e compare with a 1000W DE HPS in crop performance?

The RS 1900e's 3.0 µmol/J efficacy means it delivers more photons per watt than HPS, and its full-spectrum output matches indoor crop spectral needs throughout all growth stages. Facilities that switch from DE HPS to the RS 1900e commonly see similar or better crop results while drawing noticeably less power.

Can the RS 1900e be dimmed or controlled centrally?

Yes -- the RS 1900e pairs with Gavita's EL3 master controller for centralized dimming, scheduling, and environmental response across a facility's fixture array from one control point. It is not designed to work with the earlier EL1/EL2 controller generations.

What mounting hardware is required?

The RS 1900e works with Gavita's LED Rail System and standard commercial grow room ratchet hangers. For rail-based setups, pair it with the Gavita LED Rail System Hanging Bracket, sold separately, to keep the fixture level and secure.

Is the RS 1900e suitable for both greenhouse and fully enclosed grow rooms?

Yes -- its wide-range 208-480V input and durable build suit both controlled-environment greenhouses supplementing natural light and fully enclosed indoor grow rooms running on artificial light cycles alone. The 6-bar layout also fits standard greenhouse truss spacing without modification.
