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. High-frequency ballast 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."
