ThinkGrow Model One 4' LED Light Bar | Full Spectrum + Far Red - FR-1

Want to accelerate flowering transitions and maximize yields without the complexity of multiple spectrum channels?

The ThinkGrow Model One FR-1 LED Light Bar combines essential full spectrum lighting with targeted far-red wavelengths, providing the precise spectral control needed to manipulate plant responses and optimize flowering performance.

This streamlined two-channel system is designed for growers seeking enhanced flowering control and yield improvements while maintaining simplicity in their lighting setup.

Equipped with proven Samsung white-based full spectrum diodes engineered specifically for crop cultivation, the FR-1 delivers 234+ μmol/s PPF across two strategically designed spectrum channels: full spectrum white light and targeted far-red wavelengths. This combination provides comprehensive coverage for vegetative growth while enabling precise flowering manipulation through strategic far-red application.

The targeted far-red spectrum channel allows growers to trigger specific plant responses, accelerate flowering transitions, and increase overall yield potential by applying far-red light at optimal timing intervals. When integrated with TrolMaster controllers, this system provides automated control over both spectrum channels throughout different growth phases.

Built with the same modular plug-and-play design as other Model One components, the FR-1 operates efficiently at 90W power consumption while delivering over 54,000 hours of reliable performance in demanding growing environments.
