Transformer requirement for LED lights

[calo247]

no you can not just run any 12-24v supply, a 24v supply WILL fry the leds, the dimmer module has no idea what the led max voltage is... the dimmer is intended to be used with a light that comes with the appropriate power supply, and cut the voltage with 100% being running the lights at their normal undimmed output.

if you have a 24v supply on the input 100% will be 24v output and will fry the 12v rated leds. please do not get a power supply rated at more than 12v

trust me, i am an electrician
