ELI5: Why do LED lightbulbs use **additional** LEDs to get more lumens, rather than just use **larger** LEDs?

It's probably cheaper and more reliable.  If you have standardized LEDs that are getting mass produced for really fucking cheap, it doesn't make a lot of sense to spend time and money to design a new larger LED that produces the same ammount of light as 5 smaller ones.

Also, I'd 1/5 LEDs dies, you still have 4 functioning ones.
