Maximize yields and quality with this high-efficiency full-spectrum light, designed for 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 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 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.
