If you break a CFL at home, you are SUPPOSED to go through a fairly lengthy procedure - https://www.epa.gov/cfl/cleaning-broken-cfl ... who ever did all that ...

Thankfully LEDs have come to the rescue and seem to be a viable alternative to good old incandescents. However, I recently installed a 12-bulb fixture in my bathroom and it would have cost more for the bulbs than for the fixture to install LEDs, so I bought incandescents for it. LED lights can be found cheap on Amazon, but they are still quite pricey in retail stores; and the cheapest LED lights aren't dimmable.

Good post. What about the drop-off? Don't they lose 40% of their output within a few months.

Depends on the reputation of the manufacturer. Use Cree, or Lumiled based fixtures, and the output is guaranteed to decay less than 10% after 50,000 hours of continuous operation.
