FAQ – Gavita RS 1900e LED 208–480V
Q: What is the difference between the Gavita RS 1900e LED and the Gavita Pro RS 2400e LED?
A: The key difference is light output and design. The RS 1900e produces 1900 µmol/s PAR with a 6-bar, lightweight foldable frame, while the Pro RS 2400e delivers 2400 µmol/s PAR with an 8-bar design. Both share premium Gavita components, 208–480V compatibility, and dimming with the EL3 Master Controller. Your choice depends on the intensity and coverage needs of your grow space.
Q: What are the benefits of the 6-bar foldable design of the Gavita RS 1900e LED?
A: The foldable 6-bar design makes installation, transport, and storage faster and easier. It provides uniform light distribution across the canopy to minimize hot spots, ensures consistent plant growth, and at just 29.8 lbs, it’s lighter and simpler to mount in commercial facilities.
Q: Can I use the Gavita RS 1900e LED for the entire growth cycle?
A: Yes. The RS 1900e is a full-spectrum fixture with enhanced blue light that supports all phases of growth—vegetative, flowering, and finishing. Using the EL3 Master Controller, you can dim the fixture to precisely match plant needs at each stage, optimizing both yield and efficiency.
Q: Do I need a separate controller to dim the Gavita RS 1900e LED?
A: Yes. While the fixture runs at full power on its own, pairing it with the Gavita EL3 Master Controller unlocks precise dimming down to 10%, sunrise/sunset simulations, and temperature safety features—helping you fine-tune your grow environment and reduce energy costs.
