A budget yet quality 400w HPS lamp manufactured in Australia. These lamps have been specifically made for use in flowering although they also emit a sufficient amount of blue spectrum to be used as a dual spectrum growth/flowering lamp.
Tip: A HID (HPS/Metal Halide/CDM) bulb will drop approx. 30% of its lumen output within 12-14 months of continuous use. We recommend replacing every 3-6months for optimum plant growth and yield output!
