Too bright...

I tested my Fetaya red LED filament lamp in my E27 adapter at my room at my father home, and it was too bright and too glaring to be used as a nightlight. It also had an afterglow at turning off and the light is flicker free, which means that the driver have a capacitor, despite rated as dimmable.
It seems that the red coloring is actually a ruby, similar to IR lamps.
