FGI MH Installation


The H8 660W LED Grow Light is the perfect solution for commercial gardens that need high PPFD output. This unit is designed to be hung under shelves or close to the canopy, and it can be daisy-chained with up to four other units on 240V power. It also has a dimming knob and can be controlled by a variety of 0-10V dimmers, making it a versatile and easy-to-use grow light.


  • Internal LED driver enclosed within side rails.
  • Daisy Chain (power and 0-10V dimming - depends on voltage supplied)
  • Easy to install. No assembly required. Unfold, plug and play.
  • Comes with 120V and 240V plugs.
  • Comes with rope hangars. 
  • Universal control (TrolMaster, FGI Dimming Controller etc...)

The unit is DLC listed for rebates in the US and consumes just 660W of power while outputting 1716 PPF at an efficient 2.6 umols/j. 

An internal LED driver keeps the unit streamlined at only 2" deep making it ideal for hanging undershelves or close to ceiling allowing for maximum plant height in the grow space. 

It can be power daisy chained, up to 4 units on 240V power, reducing the number of receptacles needed in the grow space. 

It ships with a 220V cord with a 110V adapter plug, rope hangars and a 0-10V RJ-16 light to light daisy chain cable. 


Master Controller
