This is basically what’s inside those fancy LED lights. The white LED that is inside all those lights is really a blue LED with a fancy coating. For this reason, white LEDs are more expensive than blue LEDs, even if you are just buying one. One important thing to notice is that the leads coming off the LED are solid. Solid leads are like solid wire or any solid piece of metal. Bend it enough times and it breaks. So a key part of building a good LED light is to make sure the LED doesn’t move. Companies do that with a combination of good circuit boards, soldering, and sometimes coating it in some kind of plastic or polymer to really “glue” it to the board.
