Good day Elmar,
The Rania is not rated to control LED products, only incandescent and halogen. However is you require to dim LED products you could incorporate and power booster between the dimmer and the lighting load, NGRX-PB-CE. You can generate a list of compatible LED products for the NGRX-PB-CE by visiting
www.lutron.com/ledtool. Once here select NGRX Interfaces from the Lutron Control Menu, select only 240V from the voltage menu and click search. After the page reloads, scroll down to view a list of compatible LEDs. By clicking on any of the LED model number you can view a detailed report which provides you with all compatible Lutron controls, the amount of LEDs they are rated to control and the dimming range you will experience.
We have some application note about Rania controls.
