ThinkGrow FR-1 4 ft Model One LED Bar. Full Spectrum + Far Red, 90W

ThinkGrow FR-1 Puts Far Red on Its Own Channel Far red is useful, but most growers do not want it at the same level all day. The FR-1 separates it from the rest of the spectrum. One channel carries full spectrum white light, and the second carries far red only. On a TLD-2 driver the two channels dim independently from 0 to 100%. That makes it simple to add a far red boost at the end of the day or hold it back in veg. The bar draws 90 watts and puts out 234 µmol/s of PPF. ThinkGrow rates the TLD-2 and FR-1 pairing at 2.6 µmol/J. It is sealed to IP56 and its diodes are rated L90 beyond 54,000 hours. The manual lists the bar at 45.35 × 2.68 × 2.20 in with a gross weight of 1.65 lbs. The box holds one FR-1 bar with no driver or cord. Adding a Far Red LED Bar to a Model One Fixture Hang TLD-2 drivers on an MB-series mounting bar, then click an FR-1 into each one. The assembled fixture runs about 45 in long, 2.05 in wide and 4.04 in tall. Mount it more than six inches above the canopy. FR-1 bars can share a mounting bar with DR-1 or TLB bars to build a mixed spectrum. Link the drivers with TDC-2, TDC-3 or TDC-4 daisy-chain cords. A TDC-120, TDC-240 or TDC-277 splitter cord feeds power and the controller signal to each group. A TrolMaster controller can then run a far red schedule separate from the main light cycle. Drivers, cords and mounting bars are sold separately. If a room needs UV as well, the four-channel TLB-1 adds it on a TLD-4 driver. For background on how far red affects plants, see our guide to far red grow lighting. Wiring diagrams are in the Model One manual attached below. Key Features Separate Far Red Channel: Dims and schedules far red apart from the full spectrum light. 234 µmol/s at 2.6 µmol/J: Rated output of the FR-1 on a TLD-2 driver. Two-Channel Simplicity: Runs on the TLD-2 driver without the extra UV channel. IP56 Sealed: Suitable for damp grow rooms and greenhouses. Mix and Match: Shares mounting bars with DR-1 and TLB bars in one fixture.
