Think Grow 90w Model One 4 Spectrum Driver Only

The TLD-4, is a modular plug-and-play LED driver that is designed to operate a single 90-watt LED bar. Since the TLD-4 is a modular driver, it can be combined with additional TLD-4 drivers to create a complete lighting system that can fit into any size space, and provide up to 1400 umol of light. It features four spectrum control channels and can be connected to a TrolMaster HCS or TCS controller to allow for remote control and independent settings for each of the four channels. That provides the ability to have customized lighting spectrum and timing control. The TLD-4 works with the 4ft long TLB-1 or 5ft long TLB-2 LED light bars from ThinkGrow.
