ThinkGrow Model-I LED 720W Toplight Spectrum Tunable Grow Light, Each

Tunable full-spectrum top lighting with far red, 720W

Growers who light a greenhouse or a single-level room need even coverage without a bulky external driver. The Model-I puts a full-spectrum LED bar and its driver in one compact fixture, and a V-shaped LED panel spreads light more evenly so the fixture can hang closer to the canopy. It is rated at 720 W input, with efficacy of at least 2.54 μmol/J and PPF of at least 1829 μmol/s.

This is a single 720W toplight sold each. It suits growers who run a regular indoor room or greenhouse bay and want one dependable fixture per lighting zone, and it scales to larger rooms by adding fixtures on a compatible controller.

Key Features & Benefits

• Built-in driver — fewer separate components and quicker installation.
• Full spectrum plus a separate far-red channel — covers vegetative growth through flowering, and the far-red channel can be controlled on its own with a compatible controller.
• V-shape LED panel — improves light spread across the canopy.
• IP66 rating — built for wet and humid growing environments.
• Autosensing 100-277 V input — runs on common commercial and residential supply voltages.

Who Should Use the ThinkGrow Model-I

Greenhouse operators and indoor growers who light a single level of plants will get the most from this fixture. It is also a fit for growers already running TrolMaster Hydro-X control systems who want independent control of the full-spectrum and far-red channels.

Frequently Asked Questions

Q: What controller does the Model-I work with?
A: It is compatible with TrolMaster Hydro-X control systems. Other controllers are not listed as compatible, so confirm before you buy if you use a different system.

Q: What does the far-red channel do?
A: Far red is a separate light channel at the long end of the spectrum. With an external controller you can switch it on briefly after the main lights go off, which growers use to help finish the flowering cycle.

Q: What does IP66 mean?
A: IP66 is an ingress protection rating. It means the fixture is sealed against dust and strong water jets, so it suits humid growing rooms and greenhouses.

Q: What voltage does it need?
A: The fixture autosenses input from 100 to 277 V. Amp draw is 6.23 A at 120V, 3.09 A at 240V and 2.71 A at 277V, which helps you size circuits.

Q: How high should I mount it?
A: Mount it more than 2.5 ft (76.2 cm) above the canopy. The V-shaped panel is designed to spread light so the fixture can hang closer than many designs.

Q: How is it covered?
A: The distributor lists a 5-year warranty. The fixture is also registered to CE, ETL and FCC standards.
