Flicker Free LED Lightning it's the most important thing! Which one to buy?
GregAtkinson I'm going to buy some from 2-3 different sellers on eBay; presumably their stock is older. I'll keep you posted on that.
There are a few old, non-flickering ones on eBay. Here’s an eBay listing that has them for about $2 per bulb with shipping.

Here's a couple pictures showing the differences. the newer (bad) box is smaller; the older (good) box is larger.
I bought about 150 bulbs from various sellers that will hopefully last until my kids put me in a nursing home. It’s a large box, but still a very poignant reminder of my limited time on earth.
GregAtkinson Here is the "CENTRIC HOME™ Flicker-Free A21 15W LED Bulb." This is on DC mode.
Finaly, all when we get not thin line wave-style, it mean it has extremly high-freq modulation which you can see limiting threshold window? Not in ms, but in ns?

Many commercially available LED lights can still cause discomfort even at frequencies of 2-3kHz. Higher frequencies, such as 25kHz and above, can significantly reduce flicker-related issues. Some of Tridonic's LED drivers support high frequency PWM dimming, which can reach 30kHz or higher. ShineLong's high-end LED products, such as the Alpha series or the Rancher series, support strobo-free drivers and often prefer high-frequency dimming designs.
