Sunmaster Super HPS HO Bulb, 1000 Watt - 2000 K is no longer available

With 2,200 µmol in total output and 1,900 µmol in the key 400-700nm range, the 1,000-watt Sunmaster Super HPS High Output Lamp offers up to 20 percent more µmol and over 47 percent more red to far-red energy compared to other 1,000-watt single-ended HPS lamps. This impressive orange-red spectral output encourages earlier flowering and increases the total number of branches, internodes and flowers.
