ThinkGrow Model-I Plus LED 720W Toplight, Spectrum Tunable (Each)

Tunable 720W LED light for greenhouse and indoor rooms, 1 each

Growers who need even light and flexible spectrum control often end up juggling separate drivers and extra wiring. The Model-I Plus puts the driver inside the fixture and uses a V-shaped LED panel to spread light more evenly. It draws 720 W and lists efficacy of at least 2.7 μmol/J.

This listing is for a single fixture. That suits a grower trialing it in one zone, and the control options let commercial rooms scale up with several fixtures on a shared control channel.

Key Features & Benefits

• Built-in driver — simplifies installation and keeps the fixture compact.
• Four spectrum channels — UV, white, deep red and far red let you adjust the light recipe.
• V-shape LED panel — spreads light more evenly across the canopy.
• IP66 rating — suits wet environments such as greenhouses.
• 5-year warranty — gives long-term coverage on the fixture.

Who Should Use ThinkGrow Model-I Plus

Greenhouse and single-level indoor growers who run TrolMaster Hydro-X control systems and want tunable spectrum. Independent channel control needs a compatible controller.
