Properly made compact florescents last essentially forever. I have two bulbs that I bought in the 1977ish
time frame to try out the technology. Kinda big by today's standards, but fine for a lamp. They are a bulb
base with the electronics and a about 7-8 inch diameter ring florescent, all packaged to fit in a medium to large
table lamp. These have been in normal home use for over 30 years, still start quickly, give nice color light
and have lasted long enough to be a problem for the company making them, I would bet. My second
generation compact"er" florescents used in the cabin were purchased in about '95-96 and were quite expensive
for the time. IIRC, list price was about $18 each, but we found a big box store going out of business and
bought about 15 of them for $10 each, still expensive. These have been in use in the cabin since then, have
had not a single bulb failure. Of course, we are only there a small portion of the year, so compared to a full
time home, use is much less. These are just a bit larger than normal bulbs, in a glass envelope.
One possible issue with LEDs is that the light is extremely narrowly spectrum, not broad spectrum. If you look at a
spectrum of a LED it will have several different color LEDs put together to make a rough approximation of white
light but it is really only a few extremely narrow frequency bands, literally spikes on a spectrum that it makes.
I have always wondered whether this extremely abnormal light will have long term effects on humans. Seems
fine in the short run but is WAY not normal light.
When my stock of incandescents are all used up, and the quality CFLs in place burn out, I hope that LEDs are lower in price.
At this point, the combination of lots of good stuff on the shelf, extreme cost of LEDs and finally that nasty burr
under my saddle of government compulsion all add up to NO SALE for me.
I'm just about hard headed enough that if the government ordered me to have ice cream once a day, I'd
figure out a way to keep from doing it. Don't want the bureaucrats telling me what to do!
Not sure that the garbage Chinese CFLs aren't part of the plot to force LEDs on us. Current
China production are really just junk.
