Description
A 5ft, Four-Spectrum Bar for the ThinkGrow Model One System
The ThinkGrow TLB-2 5ft LED Bar is the long light bar of the Model One modular system: one 90W bar per driver, built with Samsung white full-spectrum diodes plus deep red, far red and UV on four separately controlled channels. It puts out more than 252 µmol/s (about 2.8 µmol/J), and because each bar has its own driver, you can space bars close together for high intensity in flowering or further apart for young plants in vegetative growth.
Key Benefits
- Four spectrum channels - white, deep red, far red and UV, each adjustable from a TrolMaster controller
- Build your own layout - add bars one at a time to fit any room shape
- Efficient - over 252 µmol/s from 90W
- Slim and light - 146 cm long and under 1.5 kg, with an IP56 rating
- Long life - L90 above 54,000 hours
How to Use
- Pair each bar with a TLD-4 driver - the four-channel Model One driver, sold separately. Two-channel TLD-2 drivers do not run the TLB-2.
- Power each group of drivers with a ThinkGrow Model One UK power cord (TDC-240u), which is not included and must be bought separately, and link the rest with Model One daisy-chain cords.
- Hang the bars at least 15 cm above the canopy, closer together for flowering and further apart for young plants.
- Connect a TrolMaster Tent-X or four-channel Hydro-X controller to set each channel; without one, the far-red diodes stay off. The original Hydro-X HCS-1 controls only two channels.

Frequently Asked Questions
What else do I need to run it?
One TLD-4 four-channel driver per bar, a ThinkGrow Model One UK power cord (TDC-240u) to connect each group of drivers to the mains, and Model One daisy-chain cords between drivers. None of these comes with the bar.
What is the difference between the TLB-1 and TLB-2?
Both are 90W four-channel Model One bars that run on the TLD-4 driver; the TLB-1 is 4ft long and the TLB-2 is 5ft.
Will it work with my Hydro-X?
The original Hydro-X HCS-1 controls only two channels, so the TLB-2 will not work properly on it. Use a TrolMaster Tent-X or a four-channel Hydro-X system.
