ThinkGrow M-One 4' LED bar w/ White & FR Dual Channels

A Two-Channel Bar Built Around Far Red

The ThinkGrow FR-1 is a 4-foot LED bar for the modular Model One lighting system, built with SAMSUNG white-based full-spectrum diodes designed specifically for crop cultivation.

Its two spectrum channels — full spectrum and far red — cover essential growth stages from vegetative to flowering. Targeted far-red exposure at specific times can help shift plant response, encouraging earlier flowering and supporting overall yield.

• SAMSUNG White-Based Diodes — Full-spectrum output built for crop cultivation.
• 2 Spectrum Channels — Full spectrum and far red, independently adjustable.
• Onboard Dimming Knob — Adjust output without an external controller.
• TrolMaster Compatible — Schedule targeted far-red exposure when connected to a controller.

Who Should Use the FR-1

The FR-1 suits growers who want to use targeted far-red light to influence flowering timing alongside full spectrum light.

Pairing With a Driver
