Whoa, that’s an idea. But… with my previous DIY LED projects, I ultimately wasn’t confident about the electronics required for switching light sources, and was left with too many questions about lenses, reflectors, diffusers, and how to ultimately package everything so that it feels safe for long-term home use. I made both a water cooled lamp and passively cooled one with over a kilo of heatsinks. 
For a light bulb that would connect directly to AC230… it’s tempting but probably more than I can handle.
Well, if I could remotely switch the power through different LEDs that’s good enough, or even just changing CCT by switching power off and on again. Are those possible without PWM? Blending different colors is not necessary at all.
As I wrote above, I have an unfinished project with a Meanwell driver and 2 circuits of 80-100W each, different CCT. I suddenly realized that I didn’t know if it was safe to operate a physical switch while powered on due to sparks. Image: https://imgur.com/a/mPK4sJH
TL;DR I don’t know electronics.
LED strips is also something that I feel could work, but I’m not sure how you would integrate those industrial-looking drivers in your home. I guess you buy some fancy box for it so it looks civilized? YUJI has some bi-color LED strips with compatible drivers and remote control, that package is $360 plus shipping and customs though.
Is the store active nowadays? And if so, is there a thread/guide about how to order, because there were some customizations I didn’t understand.
