Do you know ELV dimmer? Jun 07 ,2021
How do you dim a combination of a MR16 bulb and an “electronic” led power supply? Turns out that if you chop the beginning of the AC wave, it causes the led electronic driver to hum and buzz unpleasantly because of the sudden wall of AC power coming into the device. So the solution was to chop the t...
