We're sorry to hear about your experience with your LEDs not shutting off completely. We assume you are controlling dimmable LEDs? Because there is no industry standard for manufacturing LEDs, not all LEDs are designed the same. That's why Lutron has a a mobile-friendly web tool to help you select bulbs that perform great with Lutron dimmers. We specifically test to ensure that the bulbs we list on our tool are not susceptible to a variety of issues, including bulbs that will not turn completely off. To use the tool, please visit lutron.com/ledfinder.
