ThinkGrow Model-I 720w LED Grow Light


Model-I is designed specifically for Greenhouse and single-level indoor cultivation.

This fixture is a high performance LED grow light for horticulture cultivation. The compact design with a built-in driver balances the energy efficiency and human work environment. The innovative V-shape design on the LED panel improves light distribution, which lowers the height from the canopy needed as it reduces light energy loss.

Full-spectrum design with UV provides a better spectrum similar to the natural sunlight covering each critical phase of growth from vegetative to flowering. Extra Far Red spectrum channel allows a 10-15 mins exposure under Far Red, it can be applied to crops to help finish the flowering cycle faster (External Controller required).

It provides great external control ability and allows up to 256 fixtures per channel with outstanding efficiency at 2.54 umol/J.


  • Built-in driver
  • External Controllability – 256 Fixtures per channel
  • Full Spectrum + Individual Far LED
  • V-shape LED Panel Design
  • IP66 Waterproof
  • Outstanding Efficacy 2.54 umol/J

The Model-I is only compatible with TrolMaster Hydro-X control systems. With the TrolMaster lighting adaptor LMA-T, the Full Spectrum and Far Red channels can be controlled independently from the Hydro-X controllers. This will allow the Far Red channel to be turned on 10-15 mins after light off to help finishing the flowering cycle faster. One LMA-T adaptor can run up to 256 fixtures in the same daisy chain channel.

*The Model-I will operate at Full Spectrum Channel only without connecting to the controller.
