ThinkGrow M-One 4' LED bar w/ 4 Spectrum Channels

A 4-Foot Bar With Four Independent Spectrum Channels

The ThinkGrow TLB series is a 4-channel LED bar for the modular Model One lighting system, built with SAMSUNG white-based full-spectrum diodes designed specifically for crop cultivation. Four independently controllable channels — white, deep red, far red, and UV — deliver 90 watts of light, letting growers build a custom spectrum recipe rather than accepting one fixed blend.

At 4 feet long, the TLB-1 suits standard-width rows or benches, delivering the same 90 watts across its four channels as the longer TLB-2.

Key Features & Benefits

• SAMSUNG Diode Array — provides the white spectrum base across all four channels.
• 4 Independent Spectrum Channels — adjust white, deep red, far red, and UV separately.
• 90 Watts of Light Output — supports growth from vegetative through flowering.
• Modular Plug-and-Play Design — pairs with a ThinkGrow TLD-4 driver.
• TrolMaster Compatible — adjusts spectrum recipes remotely when connected to a controller.

Who Should Use a TLB Model One LED Bar

Growers building a Model One system who want full independent control over white, deep red, far red, and UV channels, rather than a simpler two-channel bar, are the intended users of the TLB lineup. Choosing between the two lengths comes down to matching the bar to a row's or bench's physical width.

About ThinkGrow

ThinkGrow, TrolMaster's lighting brand, built the TLB series as its full four-channel option, giving growers complete independent control over spectrum rather than the simpler two-channel DR-1 or FR-1 bars. Pairing either length with a TrolMaster controller keeps custom spectrum recipes inside the same automated system already running climate control.

Frequently Asked Questions

Does this LED bar include a driver?

No, it requires a separate ThinkGrow TLD-4 driver, sold separately. The bar itself doesn't include integrated driver electronics.

How many spectrum channels does it have?

Four independently controllable channels: white, deep red, far red, and UV. Each one adjusts on its own rather than as a fixed blend.

Can I control each channel separately?

Yes, when paired with a TLD-4 driver and a compatible TrolMaster controller. Without a controller, the driver still runs all four channels together at a set output.

What diodes does it use?

SAMSUNG white-based full-spectrum diodes designed for crop cultivation. Those diodes form the white channel's base spectrum.
