Nine-channel wireless LED controller TrueSpectrum Lite


Availability:  Out of Stock

* Interface flat cable:

We believe that a well-designed LED lamp does not need active cooling. Therefore TrueSpectrum Lite controller has no possibilities of using the fan cooling and the temperature sensor.
All other function of controller TrueSpectrum Lite is same as in the controller TrueSpectrum.

Supercapacitor lifetime** controller lifetime

“*” Matching connectors are included
“**” The supercapacitor can keep the clock running for 7-12 days. If the controller board is powered off for a longer period, the real time clock will be reset to the default value and you will have to set the controller date and time anew. 

When purchasing the controller, do not forget to buy the required length of flat interface cable The cable is required for connecting the controller to the drivers.
