Still in process of switching entire house and exterior to CFLs.
Thus far, I've run into these behaviors on different 13W (40W resistance
lighting equivalent advertised) CFLs.
Lights in hallway and front porch- half second delay before any illumination
at all. Relatively dim illumination to the others mentioned here. Makes me
nervous without instant lighting.
Hollywood style lighting over sink. Immediate turn-on, practically no wait
time for full illumination.
Recessed lighting in kitchen- takes about a minute before full illumination.
Quite bright when that time expires. No time delay for some initial
illumination, but, very dim initially. If switched off, and immediately
turned on, full illumination is there right away.
Believe they're all GE make. First set bought at dollar store. 2nd and 3rd
sets bought at Ace Hardware.
Why the different turn-on and illumination behaviors?
All CFL's have a warmup behavoir. After they are warm they get brighter.
Higher wattage is more noticable. Colder location affects this as well. I
have 3 yellow ones outside, this time of year they are very dim when turned
on. Some are better at reducing the initial startup time than others. You
get used to it.

They are reviewed at Popular Machanics mag about a year ago, maybe in
homeowner section and Consumers Reports. My ext floodlights take 12min
+ at 10f to get bright, a minute or so at 70f. Different brands are
made different, old ones are not as advanced. HD has the 9w which
equals 40w here for 1$, HD at Pop Mech was rated #1 in skin color look
and has a 7 yr warranty. 13w should equal 60w, compare by Lumen
Rating. Outside they are no good for motion sensors to light up quick
but they work and last I have found. I use at least 50. HD has the
best deal, light, and warranty I have found. Soft white are most like

Way too many factors to give a good absolutely correct answer.
1. Temperature is a main factor in initial brilliance. Warmming up
brings up the light level, then probably then are mounted in a
location that is cold(er) than typical interior spaces.
2. Some lamps take longer to achieve full brillance. IMHO just cheap
design. Buy from China, and you takes your chances... <g>
3. Ditto for intial light, some lamps don't seem to come on as quickly
as others. Again, low or non-existant quality control from cheap
Just because it says "GE" on the package, doesnt' mean that GE made
it, or that it is quality! Instead all the name means is that some
company paid GE for the rights to use their name.
Some simple tests may be to take a CFL that is working well in one
location and try it in a location that is not working well... Also
measure the temperatures at the socket (when off). If too cold you
will see both delayed startup and low initial light output. Not to say
you can't use CFLs in cold locations (I use one on my back deck, gets
to -20 in the winter) just that you have to comphensate for that
initial minute or so to full brightness. In my case I just turn it on
a minute before I plan to go out.
Summary: Cheap lamps with low quality control/poor design, and low
temperatures (often combined) will cause the problem.
The thing about this is that no matter how much a pain it is it won't
get repealed. The prevailing thinking will be that as long as the
public is hassled then the impetus will be there to increase the
So........why is it that no one has a toilet that can flush more than
a tissue worth again?
Put XYZZY somewhere within the subject line of any emails to me or it
will be summarily deleted.

Bulbs sold and marked as "appliance lamps" are exempted from federal and
state "ban-the-bulb" laws; so bulbs for your oven and fridge aren't going to
disappear any time soon.
LEDs love cold and so interior refrigerator lighting is going in that
direction including screw-in replacements. Lots of LEDs in store freezer
cases already. They start instantly at full output and never need to be
Some CFLs are slow to start because of the ballast circuit, not temperature.
Look for "cold cathode" CFLs; they start instantly.
If you want to raise your chances of getting a quality CFL product, look on
the package for "Energy Star" or at least the manufacturer's "800" number.
Energy Star lamps have to meet performance requirements, are regularly
tested and have to be marked so you can contact the manufacturer for a
replacement in case of problems.
If you buy CFLs only on price, sooner or later you'll get stung.
