We're sorry to hear about your experience. To confirm you're using the proper product, the MALFQ (models vary) is rated only for incandescent and halogen bulbs, so performance issues can occur when using LEDs. We do, however, offer an LED version of this product, model # MACL-LFQ-XX (xx indicates color choice), which is designed specifically to control dimmable LEDs.
We also suggest making sure your dimmable LED has been tested and approved by Lutron. We have a mobile-friendly web tool to help you select bulbs that perform well with Lutron dimmers. To use the tool please visit lutron.com/ledfinder.
If you have questions or concerns, please reach out to our Customer Satisfaction team at customersatisfaction@lutron.com, or call us 1-844-LUTRON1. We're here 24/7, so please call us any time!
