Gavita Dew Guard 600w Bulb (AFW)
"HPS-lampsHPS lamps are the standard in the market. The lamps used by Gavita are characterized by their high level of efficiency and long light retention. A major benefit of HPS lamps is the heat radiated directly onto the crop, as this encourages growth, and depending on the crop, the formation of buds and fruit.
Gavita lamps are specially developed for a high-frequency ballast. The benefit of a high frequency is that the electric arc in the lamp isn’t extinguished in the interim, creating a constant and higher light output."
