Years ago....
......PG&E (our gas/electric provider) was subsidizing the cost CFL bulbs making them extremely inexpensive to purchase.
I bought a LARGE supply at the local hardware chain store (OSH) and still have MANY.
I am one to use things up before buying new so will most likely be using CFLs for many years to come.
I do have some LED bulbs (refrigerator, hanging light with candelabra bulbs, post lamp...) Christmas lights as well.
CFLs have presented some issues for me. When they fail, they tend to do so with smoke and burning smells.
CFLs also don't "play nice" with lighted wall switches. In a 3 way switch application, the CFL flashed on and off when it was turned off so I had to replace it with an incandescent bulb.
On the flip side, LED bulbs require compatible dimmers and don't work well with "old school" dimmers.
