I bought one of these from Lowes today to do some testing. It works great on an outside light, I just swapped out one of the CFL flood light bulbs to an incandescent. The ramp up and down is fine.
I tried it in another location that has 3 CFL’s it wasn’t so great there. I may do some research on LED’s that are dimmable and may work w/out a neutral on the dimmer for that location.
I don’t know why I never thought of this before, but am so glad I read this thread!
I’ll never use the dimming feature but at least I was able to easily add a smart switch where I wasn’t able to before.
