Yes, I've googled it, but there are many different
approaches. Which one is used in domestic LED bulbs?

Varys with who is doing the bulbs. The cheapest ****
does it differently to the stuff with the long warrantys.

Don't they all use something similar to CREE LEDs?

Nope, the cheapest **** has the individual leds clearly visible.

What do you mean by that? You can always se individual LEDs can't you?

Nope, no visible individual leds with the high end led bulbs.

There's a plastic over over it.

That's actually what CREE calls a remote phosphor.

What's your point?

That you cant SEE the individual leds.
