Pro Grow 620w SE HPS 2k Globe

The new Pro Grow HPS 620W & 1000W single ended lamps exceed the output of even the best European branded lamps. All Pro Grow lamps offer up-rated components specifically tuned for use with high frequency digital ballasts. Improvements include monolithic arc tube construction, more robust frame wire material, extruded ceramic ark tubes (not molded) decreased frame wire thickness (for reduced shadow print) and low iron glass for enhanced UV penetration. Grow like a pro at half the price of equivalent Euro branded lamps (virtually all lamp brands are now manufactured in China).
