Hello Steve, we're sorry to hear about your experience. The dimming range for LEDs varies from bulb to bulb depending on the bulb's design. Due to the lack of manufacturing standards in the industry, all LED bulbs are made differently and thus are subject to different performance with different dimmers. That's why we engineered our LED+ dimmers with a low-end adjustment, which allows you to adjust the dimming range of your LED bulb. For easy step-by-step instructions for adjusting the dimming range on your Maestro LED+ dimmer,, please see step 7 on the following guide:

We also suggest making sure we've tested and approved your dimmable LED. Lutron offers a mobile-friendly web tool to help you select bulbs that work best with Lutron dimmers. To use the tool, please visit lutron.com/ledfinder.
