Lutron Rania dimmer switches are suitable for use with a variety of lighting types including some LEDs. This includes GU10s, MR16s and integrated LED downlights. Lutron Rania dimmer switches contain both trailing edge and leading edge dimming types. When dimming LEDs you may need to use the Danlers RESLOADE which provides stability to the circuit and resolves low load issues.

Available in a choice of three finishes with many others available on request. Multi-way dimming can be achieved by ordering an additional accessory (or slave) dimmer.

LED Compatibility

Although this dimmer switch has both leading edge (MLV) and trailing edge (ELV) dimming settings it doesn't work with every LED on the market.

To change the settings of the dimmer you need to go into the advanced programming settings. The most suitable for setting for LED is usually trailing edge (ELV) with blip mode on. If you're dimming the Halers H2 Pro you must set it this way otherwise the dimmer can send a pulse output which can cause the H2 Pro to fail. Once these settings are made it will function perfect well.

The advanced programming instructions can be downloaded here.

Some LED lights may flicker with the Rania, fitting a resistive load such as the Danlers RESLOADE or Aurora AU-LR50 can often solve this. We've found this can stabilise the load and allow it dim high loads of LED tape using one of our TRIAC dimmable LED drivers. When the resistive load is installed it mainly works better on leading edge mode (MLV) but it's worth testing with each type to ensure your getting the very best, flicker free dimming range.
