ThinkGrow Model-I Plus LED Grow Light 720W. 1,944 µmol/s, 4-Channel Spectrum

ThinkGrow Model-I Plus 720W: Four Channels in One Slim Bar The Model-I Plus shares its chassis with the standard Model-I, but the diodes behind the lens are split four ways. UV, white, deep red and far red each run on a separate channel. The fixture is rated at 1,944 µmol/s from 720W, an efficacy of 2.7 µmol/J. It shows an average of 684 µmol/m² with the bar hung 2.5 ft above canopy, which is also the minimum mounting height. Coverage runs 4 x 4 ft in flower and 5 x 5 ft in veg. The V-shaped bar measures 45.24 x 4.36 x 6.46 in, weighs 22.33 lbs and carries its driver inside. Input auto-senses 100–277V, drawing 6.23A at 120V, 3.09A at 240V and 2.71A at 277V. Power factor holds at or above 90%. The housing is IP66, rated L90 above 54,000 hours under a 5-year warranty. What a 4 Channel LED Grow Light Changes in the Room Separate channels let one fixture act like several. In veg, many rooms lean on white and trim deep red to keep internodes tight. Through flower, deep red climbs, and far red comes on for short end-of-day treatments that can speed the flowering response. UV is normally saved for the final weeks. Every change happens from the controller, with nothing to swap on the ceiling. Recipes are set through a TrolMaster HCS-2, HCS-3 or a Hydro-X with the LMA-T adapter, and that hardware is part of the real cost. Without it, the fixture cannot give you what separates it from the plain Model-I. The slim bar casts little shadow, so it fits greenhouse benches as well as sealed rooms. Its tall minimum hang keeps it out of stacked racks, though. Rooms on three-phase service should look for the 347–480V version of this fixture. Key Features 1,944 µmol/s at 2.7 µmol/J: Full flowering intensity for a 4x4 bench from one 720W bar. Four Independent Channels: UV, white, deep red and far red each tune separately for veg, flower and finishing recipes. Far Red for End-of-Day Treatments: A short far-red pulse at lights-out can speed the flowering response. V-Shaped Bar with Built-In Driver: Little shadow under greenhouse glass and nothing remote to mount or wire. IP66 Housing: Stands up to humid rooms, spray drift and washdown between crops. TrolMaster Recipe Control: HCS-2, HCS-3 or Hydro-X with LMA-T runs channel recipes and group schedules.
