Are name-brand low-energy fluorescent "Green" bulbs any brighter than store brand?

 Just got a 4-pack of the Walmart "Great Value" version of these energy-
saver style fluorescent 23w bulbs which they claim are equivalent to a
100w incandescent bulb. Not even close. It's about like a 40w bulb.

Are the name brand bulbs of this type any better?

A 23 watt CFL lamp should put out a great deal
of light. One thing I have found when dealing
with a number of CFL lights is the fact that the
lamps have a warm up period. The colder the ambient
temperature the more time it takes the darn things
to reach full brightness. I've installed them in
the bathroom exhaust fan/light fixtures at several
business because of the long life of the lights and
soon discovered that in the wintertime it's like a
40 watt incandescent until about 10 minutes later
when it's as bright or brighter than a 100 watt
standard bulb. In the summertime, flip the switch
and it as bright as ever. I imagine that the more
expensive CFL lamps will perform better over a wider
temperature range.

TDD

 
I like that "feature" in the bathroom, because the light doesn't blind me as
badly when I turn it on at night...

 
Okay, I see it gets considerably brighter with time. However, this
seems like something of an annoyance if I want there to be light
*now*. Sort of like revisting TV's that need warming up or something.

 
Indeed.  When we built out house my wife had them put in special
switches that slowly raise the light level because she hates being
blinded.  When we started switching to CFLs on other lights we hardly
noticed.

Some brands are much quicker than others, too.  And some lines within
a brand.  Unfortunately no one puts "full brightness in 47 seconds!"
on the packages.
