LUMii Black 720w - LED Grow Light

The Lumii Black 720w LED grow light cleverly bridges the gap between HPS/HID and LED grow lighting with its innovative design, and is easily able to outperform 1000w SE HPS lamps. Due to its relatively low price for a large LED strip fixture, a return on investment is quickly and easily achievable with this light.

Lightweight, full spectrum and easy to install, those looking to make the transition from HPS to LED will be more than happy with what this light offers. You'll be able to select from 4 power settings: 250w, 400w, 600w and 720w; with each providing vastly more usable light and with a much better spread than their HPS equivalent.

For those already using Lumii Black HPS fixtures, further savings can be had due to the fact that existing ballasts can be utilised. Simply select an option from the drop down menu.


  • Far superior light spread and output compared to HPS
  • 2.6 µmol/j
  • Lightweight and Easy to Install
  • Remove Ballast mounting option (cable sold separately)
