So what else is available in state-of-the-art LED controls? It seems what we really need is a sort of closed-loop device that looks at the incoming voltage and maintains the constant current feeding the LEDs even as the voltage fluctuates,…

What if we had a type of resistor which could accommodate the changing voltage? There is such a device, and it is used by many LED cluster manufacturers. The device is called a Linear Regulator, and it is a small step up in control technol…
