Oh and by the way, I am a computer scientist and a developer and I know enough to say that a fucking reversioning of the old firmware would cost you nothing, except if you did something very wrong with these lamps.
I don’t want even open this stuff to flash through its serial inputs a fucking firmware found on the web course these bulbs work with 220volts and God only knows how much heat they generate. I think that summer would be a constant fire risk for these (but really unlucky) poor bulbs.
I’m really sorry to be rude but what the hell are you doing. It’s your work or your hobby to support the brand?
