I am just starting to wire my new weekend cabin and I am wondering about
using 22 watt CFL or 20 watt florescent bulbs for area lighting.

My inverter produces modified sine ware, if this is relevant.

I have used CFL in my other weekend cabin with no problems, but the new
one is larger.

If the power usage is similar, I would prefer the florescent bulbs for
area and CFL for spot lighting.

Any one done a comparison?

I have installed most;y CFL bulbs in my newly built home.

I believe you will find most will tell you that CFL bulbs do not last long,
despite all the BS about them. I would go with what you said, hands down. I
have had about 40% of my Phi;;i[s CFLs burn out within one year.

 The long tube bulbs seem to give proper light immediately and the CFL ones
take minutes to "warm-up" to temperature. If they weren't so cheap to run I
would remove most of them, where I could. Get the tubes with electronic
ballasts. It became public a few years ago that the ballasts were a huge
concern on energy consumption, too.

I recently purchased some 40/9 watt  450 lumen small globe(spiral

at Target,

 They turn on instantly, with 60-70%  brightness the moment the switch
is turned on!!!!

(After trying out one, I went back and purchased 3 more)..

They have a limited five year warrantee.. (@4hours  day).  

These are the fastest turn on CFL bulbs I've ever seen on the market.
Perfect for bathroom usage,.

Moral to the story.. keep on looking..

 I have purchased some ones that have a quick warm-up time and work well.
Apparently Phillips CFL units are not them...well the later ones purchased.
There isn't much GE bulbs around here but I intend to look next time.

I purchased mostly 6500K bulbs for my home at first but eventually foundthem
too "cold" for general usage.
The 5000K are a little warmer but appear to have a red glow to them.
The 3000K seem to be passible but hard to get the second time around.
The 2700K appear to warm and yellowish for me, depending on the fixture.

I find most CFLs very crappy light in overhead pot fixtures.

I have a 14W LED over my sink now but it appears to be overheating and cuts
out the thermal O/L in the fixture and then retriggers the motion detector
**SIGH**. The single LED source has the old halogen problem with a pinpoint
lightsource. Lots of bright by appearance but hard to actually see due to
glitter on everything. (unless buying a diamond ring...LOL)

 Time for an eighth motion detector. I have run into some crap with that
too.

Actually, I prefer slow-on lamps for my bathroom.  Reason?  It's for when I go
in there in the middle of the night.  With instant-on bulbs, I find it blinding.
