Family is mostly OK on it. We used to have issues with iOS devices not noticing some new messages & calls, but that seems to have stopped a few months ago. Family is usually impatient about me getting to my phone and rings me using 3 different services in a row, one of them Snikket xD
Have not yet managed to get any friends onto it.
The phosphor absorbs some of the blue and downconverts it to green and red. Some of the blue is let through for us to see. The mixture of R, G and B looks like white to us (but not necessarily to other animals with different cones in their eyes).
I’ve never seen a red LED die inside a white LED. I’ve only ever seen blue dies on their own.
Technically UV-pumped white LEDs exist, but they’re rare and I’ve never seen one. They’re less efficient and require a third phosphor (to make the blue).
You can remove the yellowish looking phosphors on the LED with a small pick to reveal the blue die underneath. Fun fact: some high-power “red” LEDs are actually blue leds + phosphors, not that it’s a particularly good choice but it’s a thing: https://halestrom.net/darksleep/blog/018_led_cob_cutting/
