ELI5: Why are LED light bulbs so expensive while LED diodes are so cheap?

Diodes are literally a dime a dozen, but a quality LED bulb is at least $10 in the US. What gives?

In addition to the difference in cost caused by adding fixtures, structure, electronics, power flux capacitors etc to the LED, costs also increase because LED bulbs are rather new and aren't as refined as Incandescent or CFL bulbs, and probably aren't made in as large quantities.

Over time, you'll see further improvements in LEDs, costs will decrease, and they'll become the pragmatic choice for both the long term and the short term.
