Your comment is just regurgitating tech specs. In reality, the bulbs that are at hand vary so much in quality, that tech spec discussions are almost useless. The flickering is a real issue. I'm not aware of any standard way of rating the flickering of LED bulbs; they can vary from really bad (literally dark 50% of the duty cycle because one stupid diode) to decent (bidirectional diodes), to very good (full voltage regulator).

It’s not, though.

First, this driver actually specifies flicker, and it has a credible number. Second, I own several and have tested them. Performance is excellent. It dims well, too. If you want a crappy driver, you don’t need to spend $25 for it :)

Second, this LED chip is a serious one, with a serious data sheet, intended for people building their own fixtures.

Thanks, your posts were illuminating. I'm not looking forward to replacing my ancient quartz floor lamp, but I'm not sure I'll be able to buy a 3rd replacement bulb, when it finally goes out.
