For reliable and powerful lighting solution for small and large commercial grow rooms, this Gavita RS 1900e is perfect.

Maximize yields and quality with this high-efficiency full-spectrum light, designed for cannabis cultivation and large-scale grows.

The Gavita RS 1900e produces 1900 µmol/s PAR with an efficient 3.0 µmol/J, delivering a broad white light with an enhanced blue spectrum. This full-spectrum fixture supports vigorous growth from veg to bloom, with studies suggesting potential boosts in terpene and cannabinoid production. Designed for commercial and high-performance indoor grows, it ensures even light distribution and deep canopy penetration for maximum yields.

Why It's the Smartest Investment

HPS systems can't match the efficiency and uniformity of the RS 1900e. With lower heat output and higher light intensity, it's ideal for high-light cannabis cultivation, vertical farming, and large-scale grows. Its balanced spectrum provides optimal plant response through every stage, making it a one-light solution for serious growers looking for higher-quality harvests.

Is the Gavita RS 1900e Energy Efficient?

With 3.0 µmol/J PPE, it outperforms HPS fixtures (1.3–2.1 µmol/J), meaning more light per watt, lower energy costs, and reduced heat stress. If you're upgrading for better efficiency and higher yields, this is the light to get.

FAQs

How many watts do I need for my grow space?

The wattage depends on the size of your grow tent or room. A general guideline is 30-50 watts per square foot for high-light plants like cannabis. For example, a 2x2 ft area may need 100-200W, while a 4x4 ft area may require 400-600W for optimal coverage.

What is the difference between full-spectrum and red/blue LED grow lights?

Full-spectrum LED lights mimic natural sunlight, providing a balanced mix of blue (for vegetative growth) and red (for flowering and fruiting) light. Red/blue LED lights focus on specific wavelengths but may not support plants as effectively as full-spectrum lights.

Does Gavita offer energy rebates for their grow lights?

Yes! Gavita offers energy rebate programs to help offset the cost of upgrading to high-efficiency grow lights. We will assist you in accessing these rebates. Visit our Energy Efficiency Rebate & Incentive Programs page to explore available savings.

Can Gavita lights help reduce my electricity costs?

Yes! Gavita’s high-efficiency LED fixtures produce more usable light per watt, reducing overall energy consumption. Plus, lower heat output means less cooling is required, cutting down additional energy expenses. This leads to a significant drop in electricity costs over time.
