The DR-1 gives that red its own control. One channel carries full spectrum white light, and the other carries deep red. On a TLD-2 driver each channel dims separately from 0 to 100%. Growers can keep a balanced spectrum in veg and lift the red channel for flower. The bar draws \u003cstrong\u003e90 watts\u003c\/strong\u003e and puts out \u003cstrong\u003e243 µmol\/s\u003c\/strong\u003e of PPF. That makes it the highest-output two-channel bar in the Model One line. ThinkGrow rates the TLD-2 and DR-1 pairing at \u003cstrong\u003e2.7 µmol\/J\u003c\/strong\u003e. The housing is sealed to IP56, and the 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.\u003c\/p\u003e\u003ch2\u003eBuilding a Fixture With a Deep Red LED Bar\u003c\/h2\u003e\u003cp style=\"text-align: justify;\"\u003eHang TLD-2 drivers on an MB-series mounting bar and click a DR-1 into each one. The finished fixture measures about 45 in long, 2.05 in wide and 4.04 in tall. Mount it more than six inches above the canopy. DR-1 bars can share a mounting bar with FR-1 or TLB bars for a custom mix. Connect the drivers with TDC-2, TDC-3 or TDC-4 daisy-chain cords. A TDC-120, TDC-240 or TDC-277 splitter cord then carries power and the controller signal to each group. Hydrofarm lists dimming from an onboard knob or from TrolMaster controllers. With a controller, the red channel can follow its own schedule through the day. The driver and power cords are sold separately. For far red or UV control, the FR-1 and TLB-1 are the matching options. The attached Model One manual shows the complete wiring layout.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\u003cul style=\"text-align: justify;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeparate Deep Red Channel:\u003c\/strong\u003e Raises or lowers red independently of the full spectrum light.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e243 µmol\/s at 2.7 µmol\/J:\u003c\/strong\u003e Rated output of the DR-1 on a TLD-2 driver.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo-Channel Driver:\u003c\/strong\u003e Runs on the TLD-2, the simpler of the two Model One drivers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIP56 Sealed:\u003c\/strong\u003e Suitable for damp grow rooms and greenhouses.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMix and Match:\u003c\/strong\u003e Shares mounting bars with FR-1 and TLB bars in one fixture.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp style=\"text-align: justify;\"\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\u003ctable style=\"width:100%;
