And while I’m sound liking a crazy person talking to myself 
…
Another good reference:
Lutron’s LED product selection.
I went there and specifically searched for LED bulbs tested with Reverse phase dimmers in the past 2 years.
And there it is, the same GE Relax bulb from Lowes that won’t work with the LZW36. It works with a few of Lutron’s reverse phase dimmers (MOSFET) from from 2% to 100%.
And knowing Lutron we all know they wouldn’t considered it passed a test if it was flickering all over.
Lutron search page:
The point here is that the light bulbs I’ve been testing are supposed to work.
From @EricM_Inovelli on an old post where apparently people are talking about similar issues:
So this is something that I have really pressed the firmware team on and the response I have received is that it is a hardware limitation […]
Having said that, there are varying bulbs that may perform better with the device than others. So your experience may be different from other users.

Two things here: MOSFET is clearly not the limitation, I would say it is the solution. I think there is something wrong with Inovelli’s design.
As for there are “varying bulbs that may perform better”… I just wish you could name one, I would buy it and be happy
