I own a recently built smart home. Last weekend I added LED under cabinet hard-wired lights using wires installed during the build. I changed out the regular switch with a Lutron dimming switch. The switch is on the same circuit as the overhead kitchen lights. Now my overhead kitchen LEDs will dim to almost nothing when I turn their switch off (not a Lutron switch) and have to turn the Lutron switch on and off to get them to completely turn off. Any ideas as to why and how to correct the issue?

There are half a dozen ways one could do this, but I would do it this way
- Purchase 2 Lutron RF Maestros. ( The RF part is important, as they sell none RF Maestros too) ( for non dimming use MRF2-6ANS )
- One Pico wireless switch
- One Pico switch plate adapter
- One 2 gang decor plate
- Change both switches to the RF Maestro and put the Pico next to the switch that controls the recessed lights using the Pico adapter and 2 gang wall plate. (No cutting necessary).
- Program the Pico to turn on both RF Maestros and you're done.
- If using electronic or magnetic LED the Maestro will need to be compatible and same goes for the recessed lights. But since you are not dimming these you do not need to worry about that nor would you need to worry about the wattage.
This is probably the LED driver inside of your flood lamp enclosure discharging any charge that is left in its circuitry. I couldn't imagine this being in issue, especially is its a very short flash

There are lots on compatibility issues with dimmers and LEDs. LED lights are not as simple as the old incandescent lamps. They have little AC to DC power supplies (called "drivers") built into them because LEDs work on very low voltage DC power. Then there are literally dozens of different designs of "dimmers" and many of the electronic ones have what's called "leakage current" through them even when off. When used on circuits with resistive devices on them, like the old incandescent lamps, the leakage is so low that it is undetectable. But because the LED drivers are designed to be very efficient and the LEDs don't consume much power themselves, this leakage current is often enough to keep the drives and LEDs excited enough to "glow".
The solution is to only use dimmers that say they are SPECIFICALLY designed for use with LED lamps. These will usually have a detectable OFF detent in the slide / rotary knob that is used for dimming. The totally electronic type where there is no slide or knob are the type that usually don't work to totally turn off LEDs. So you either change out the dimmer or learn to live with it.
