Has anybody here used Commercial Lighting 14w spiral lamps before?

Hi, I was looking for a lightbulb and all I could find were these 14w
spiral lamps that we've had laying around forever. I tried them and they
look great! They don't flicker like our other older flourescents and
they seem whiter.

I also tried some Ikea 11W ones that we had but the color isn't quite as
white. Does anybody here know what the CRI or color value is for the
Commercial Lighting 14w spiral lamps is?

These sure appear to me to be 2700 K with CRI of 82. Problem is, many
other compact fluorescents have the same specifications.

Now for some compact fluorescents that are apparently or obviously
enough other than 2700 K with CRI of 82:

1. Some have a different specified color temperature. Look for color
codes such as /SPX41, /841 or /D841 (for 410K versions) for example.

2. In recent years, Sylvania appears to favor 3000 K over 2700 K for a
"usual warm color" compact fluorescent, and I have noticed a trend for
Sylvanias to be more-pinkish less-yellowish than incandescent.

3. 2700 K twintube compact fluorescents on magnetic ballasts appear to me
to have some trend of being more-pink less-yellow than other 2700 K types
that have electronic ballasts.

4. "FUL" types, often 12 watt, which normally come in "cool white" (4100
K with CRI of or close to 62) or "warm white" (3000 K with CRI of or close
to 53).

5. Dollar store compact fluorescents are a different animal. I have seen
11 different models, with only one ("Capitol Electric") having either a
triphosphor spectrum or a reasonably incandescent-looking color (it has
both). "Fieldbreeze" models have a purplish sort of "warm white" color
and a spectrum that appears to me to have a CRI in the 50's or 60's.
Both of two "Lumilar" models, all five "Telstar" models that I have seen
(including four that I saw in packages saying "soft warm white light") and
the one "Volt Power" model that I have have a "daylight" color, and
usually (not always) a little noticeably more blue than 6500K.
Oh, and 10 out of 11 dollar store compact fluorescents appear to me to
have light output in or close to the 325-400 lumen range, regardless of
claims ranging from 60 to 125 watts "incandescent replacement" and one of
these with an actual lumen claim (550 lumens). The one not in/near this
range was lower, looking like about 250 lumens to me.
