Actually, many CFL’s have internal voltage regulation and are more tolerant of voltage variations that incandescent bulbs.
Incandescent bulbs are very sensitive to voltage verses lifespan. Raising the voltage 10% drastically reduces lifespan.
CFL’s are sensitive to spikes as you say (as in causing failure) but so are virtually all the other electronic devices you have in your home.
I used to purchase incandescent bulbs rated at 130 volts for our lab. We got much longer life out of them.
Which is why people use surge suppressors for electronics. Most people don't buy them for their lights though. All my electronics are on surge protector except for alarm clocks. Even my cordless phone base is on protection. Oh BTW I also buy commercial grade bulbs. They will take lots of abuse. For example you put a standard bulb in say a five story building there is a good chance it won't last a week possibly not a day. I buy what we used at work in the six story building and no problem. Multi story buildings higher than say three stories due to internal support systems and structural factors tend to vibrate a lot. On most bulbs at present voltage I get nearly a year use.
