Thank You electronupdate! The microscope views of the arrays under the phosphor were cool! No flicker is a big surprise for such a cheap bulb from China. I expected no filtering at all. Amazing! Wonder what that array would have done with diminishing sine wave off an autotransformer, just at the cut off-point? Maybe not much different than what you had, due to it's solid state controls. If a designer knew that the user had varying level of sign wave input, perhaps there could have been SOME dimming.
Thanks for what you do!
Experiment on cool stuff, instead of forum conversation involving assumptions and endless arguments of STUPIDITY! You just tear stuff apart and show us all! REFRESHING!!!
I guess China's Filabulb is one of the patent holders.

Also this site sells the filaments. Some specs there. 10mA @ 75-85 input voltage with 120-130 lm/w & 90-95 CRI

These guys have the glass enclosure down RIGHT! (it looks more like the vintage looking carbon filament shaped bulb we are all familiar with)

Edit... That site is not pulling up the photo now, but it had a photo of a LED powered filament bulb in the classic edison carbon shape. But at 6X the cost! (compared to Ebay $10 vers)
It can be seen here in the 5th row from the top in all its Australian glory...

Someone should let Filabulb know how important the enclosure is in many applications! Perhaps they could supply lamps to directly to the "lovers of the" Edison carbon filament market directly. They would probably crap their pants if they knew they could get $60 (US equiv) in an vintage Edison looking enclosure.
They are prob a young company that doesn't understand the "retro" market. Or they just don't care, and want to push volume.
They are LEDs with phosphor. No magic.
I say it IS magic! Lest no one up till this point has produced the retro look of a filament, WHILE doing it in LED's. NOVEL! From an artistic perspective, anyway. Think what this could do for the EL wire market! It is much brighter.
