problem with dimming LED lights

We purchased a cheap dimmer off Amazon which advertised "suitable for LED", but when we hooked up some of the lights we have, the lights started flashing instead of dimming. Dimming worked OK for incandescent bulbs. Looking around for solutions, found these videos which gave some good info.

Apparently the issue is that those LEDs which are sold as "not dimmable" (or in our case which specifically don't say "dimmable") contain an SMPS with a capacitor across it, so the pulse width modulation of the dimmer circuit causes it to flash instead of dim. 

Apparently we can dim such bulbs using a capacitor - https://www.youtube.com/watch?v=JH68wBXO5j0 . But then we can only have discrete dim levels, and probably the light will just cut out completely at some point. 

Using duct tape, parchment paper etc we can physically block the light and thus dim it too,

But in our case, creating a motorized mask like the above seems more difficult than just buying some "dimmable" LEDs. So the next step might be to explore such products.
