Oh that’s cool, I don’t know which particular bulb you’re using but there’s this bulb that charges whiles being on , connected to electricity and still stays on after there’s no electricity. That’s what we use at home. I don’t know if you know it , if not I’ll ask my brother what brand it is.
That’s what I’ll recommend, hearing the light became dimmer after adding the diffuser.
Wait, unless this bulb doesn’t even use electricity at all.
