Hello brycenesbitt,
Thank you for your post!
The Caseta dimmer is a digital control. Because of this, there is no mechanical relay inside which turns the lights on and off. As a digital control, there is a very small amount of electrical current that runs through the circuit when the lights are off. Some LEDs react to this current by dimly glowing in the off-state. There is no safety concern with this happening, but there are ways to stop this from happening.
The first is replacing one LED with an incandescent or halogen bulb. Incandescent bulbs in essence act like sponges absorbing the current leakage and should make the lights turn off. However, the color temperature and lumen output will more then likely not match.
The second solution is using an LED on our LED compatibility tool,
www.lutron.com/compatibility (

I understand this is a rental, you can always include this link in your rental documents to help tenants make the best design decisions and we are open 24/7 at 1-844-588-7661 to answer any questions they may have.
The third is changing the Caseta dimme to a analog dimmer such as the DVCL-153P. This has no power draw in the off position and fully turns off the circuit, this is a guaranteed solution to resolve your issue.
Keep in mind using this analog dimmer will prevent you from using a Smart Bridge and Pico remotes.
The fourth solution is changing the Caseta to a neutral based dimmer, such as the PD-10NXD, and pulling a neutral to the wallbox. The neutral helps to bypass some of the power draw from going to the LEDs, this typically alleviates the issue, however we cannot guarantee this solution.
Hope this helps!
