Nothing wrong with capacitive droppers for things like LED bulbs, my point was more about the quality of the components used in the capacitive dropper.
It’s my own antidotal evidence but I think I’ve had one LED bulb where the LEDs have failed and the rest have been a bad power supply (well not even “bad” more “aged out”). Because of their construction fixing the bulb is often more hassle then it’s worth except for the learning experience.
If you are making such products and you are completing in the in the low price point market, shaving cents off the cost of your caps soon adds up. However once you are no longer counting pennies you don’t mind splashing out on better quality caps.
