IF you are going to try and use an LED dimmer, you need to make sure your awning lights are on their own ground. LED's dim via pulse modulation and will not work with a shared ground.
I replacer my white strip with a set of color changing (to keep DW happy) but dimmable. Love being able to run the lights at half brightness instead of lighting up my site like a stadium...
