ThinkGrow Model-I LED Toplight - 720W - Spectrum Tunable Full Spectrum with Far Red - 45.86 in

Even toplight coverage with a built-in driver - 720W

Lighting a greenhouse or single-level room usually means mounting a light and a separate driver, then fighting uneven coverage. The Model-I puts a full-spectrum LED bar and its driver in one fixture, and its V-shaped LED panel spreads light across 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 running a regular indoor room or greenhouse bay who want one fixture per lighting zone, and larger rooms can add fixtures on a compatible controller.

Key Features & Benefits

• Built-in driver — fewer separate components and quicker installation.
• Full spectrum plus far-red channel — supports vegetative growth through flowering, with far red controllable on its own using a compatible controller.
• V-shaped LED panel — spreads light more evenly 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 ThinkGrow Model-I

Greenhouse operators and indoor growers lighting a single level of plants will get the most from this fixture. It also fits 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 a compatible controller you can control it independently of the main spectrum, which growers use to manage light timing during flowering.

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 evenly across the plants below.

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