>I've already replaced dimmers to work with LEDs. While not impossible - the LED driver is a switch mode power supply, most of them would be universal one taking 90V-260V with rather variable frequency. What dimmers do - they chop the sine wave, normally that would not affect too much the driver (aside made them hot or require more bulk capacitance, which they lack) - so they have to know that the sine wave was chopped and react by reducing the duty cycle, reducing the brightness of the LEDs. That complicates the driver, however if you don't keep the LEDs at full brightness and they are not hot on touch - they should last. The other option would be communicating through the zero cross of the sine wave, but I doubt very much it's the case. The external dimmer is not a smart feature but more like necessity, unfortunately.
