ThinkGrow LED Model-H Plus Grow Light

Model-H Plus is a true 5’ wide LED grow light designed to be used in indoor grow rooms for high PPFD cultivation practices in vertical farming.

The fixture has a total of 3368 pieces of highly efficient top-bin diodes with a total wattage upgraded to 720 watts, resulting in an 18% PPF increase in performance.

Users can have onboard dimming or adjust the spectrum and light intensity by connecting the fixtures with a controller. Four spectrum channels including UV, White (full spectrum), Deep Red and Far Red are fully controllable to customize your desired spectrum/recipe of light your plants need. (Only available on the TrolMaster HCS-2/3).

The patented plug-and-play light bar design also offers ease of installation and facilitates future maintenance.

Tech Sheet  

Ultimate Controllability

Model-H Plus is only compatible with TrolMaster Hydro-X control systems. Up to 256 fixtures can be controlled in the same daisy chain channel by using the LMA-T adaptor. When connecting to the original HCS-1 controller, the full spectrum channel and the Far Red channel can be controlled independently. The Far Red channel can be turned on for 10-15 mins after the light is off to help finish the flowering cycle faster. When connecting to the HCS-2/HCS-3 controller, the same Far Red function can be implemented and an advanced spectrum tuning function is available for creating the desired lighting recipes.

Adjustable Spectrum

The spectrum tunning feature allows growers to experiment with spectrum recipes for different crops and different stages. It can be achieved by the on-board dimming knob or controllers.
