I added these to an order from AliExpress to check out how they looked and what the circuitry was like.

The circuitry isn't too bad, with an unusual control chip.
My only real issue is that they have done the common thing of pushing the intensity to the max, when this type of bulb seems more suited to low level decorative use. The LED filament in the simpler shape bulb did have quite a strong band of blue light from the LED chips under the phosphor.

Here's the listing I ordered the bulbs from, but note that I also ordered a star which had a section of LEDs out in it, so the quality isn't guaranteed. The listing may act as a springboard to other similar sellers.
