So LED lamps are about 20% cheaper than CFL

For both LED and CFL, the main failue mechanism is the electronics
that are used to change the 120V to the higher, or lower, voltage
that these lamps actually use....
The light source themselves are very long lived. The electronics
are
not. A power spike that an incandescent can ignore can easily wipe
out the high voltage inverter in the CFL base, or the current
limiting
capacitor and reverse diode in the LED base.

You have to look at the entire assembly, and not just what the
manufactures publishes as "lamp life"..... You will NEVER get the
claimed numbers if you live in a place where there are power outages,
thunderstorms, or higher temperatures....
