Hydrofarm DX400HPS High Pressure Sodium Lamp;

Digilux lamps are now improved! Digilux high pressure sodium (HPS) lamps are favored by growers because of their wide color spectrum and efficiency. They are engineered for use in digital ballasts and feature enhanced red and orange spectrum, better color uniformity, longer lamp life, and less lumen depreciation. Digilux lamps can be used in both vertical and horizontal fixtures. Digilux HPS lamps offer superior performance compared to traditional HPS lamps. Digilux HPS lamps deliver 25% more energy in the red and orange spectra than many lamps of the same type and wattage.
