The TLB-1 is the 4 ft light bar at the heart of ThinkGrow's modular Model One system. Each 90W bar carries four spectrum channels — white, deep red, far red and UV — and plugs onto a TLD-4 driver (sold separately), so you can add, remove or re-space bars as your canopy changes instead of replacing whole fixtures.
