Gavita RS 1900e LED 208 – 480V

The Gavita® RS 1900e produces 1900 μmol s-1 PAR and an impressively efficient 3.0 μmol/j and delivers a broad white light with an enhanced blue spectrum, which some studies show may intensify secondary metabolites, such as terpenes and cannabinoids.

This powerful, full-spectrum light source is intended for full-term plant growth – from the vegetative stages to higher-light-requiring bloom and finishing stages.
