Going insane ...

I'm having trouble with some Lutron products, and I'm rapidly going insane. Hopefully someone here can point me in the right direction. Here's my story ...Setup: 2 bathroom lighting fixtures, initially controlled by a Lutron Diva DV-600P. The bulbs were unknown spec halogens/incandescents. We never really noticed that the lights never actually dimmed at all (wasn't originally supposed to be a dimmer anyway), but they turned full-on and turned full-off, so we were happy. Ah, those were the days … Then the problems began:1) First, one of the bulbs went out. I happily thought I could switch to LEDs, so I bought a pack of these: https://www.amazon.com/gp/product/B0...ie=UTF8&psc=12) As soon as I installed one, I noticed it seems bright enough, but way too cold. So I ordered a different pack, with warmer temps: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 3) When the new bulbs arrived, I installed them, only to find that they were quite dim, and barely dimmable - they had about two settings, and both were bad. They also flickered to a varying degree. 4) … so I switched back to the colder bulbs, but they were doing the same thing. It *seemed* like those had been brighter before, but all the LEDs at this point were not working well with the dimmer …5) … so then I stuffed the original working unmarked halogen/incandescent in just to get some light back … and it didn't work now. 6) I figured I had maybe gotten oil on the bulb, or broken the filament when I was uninstalling, so I ordered a pack of these now: https://www.amazon.com/gp/product/B0...ie=UTF8&psc=17) When these arrived, I was eager to be done with the whole thing … and yet they didn't work AT ALL. Like, darkness. The LEDs still gave a paltry, flickering light. 8) Now I had the theory that the dimmer had been burnt out at some point, either before when it didn't appear to, well, dim, or after, when I hooked up LEDs to a non-LED-supporting dimmer like the Diva, so …9) … I ordered and installed a Maestro MACL-153M.10) Long story short: exact same situation: LEDs flicker in a totally useless, medium setting, and the halogens that I ordered above were totally dark. I went through the "configuration" to set the low and high end a bunch of times, but when in that mode, the LED bulbs would never stop flashing (not flickering here, full on flashing).So … there we are. Thoughts on how I got here, and how to make this problem go away? I'm frankly baffled at this point.
