Good Bulb
The n:vision CFL line is one of my favorites.
The 23 watt bulb is marked 2700k and is marked warm on the package. It is good for living rooms and kitchens. I’ve been using them for a while. My wife does not notice when I switch them out.
Many manufacturers don’t mark the kelvin, or light temp. I like that this one is marked.
The bulb is 4 3/4 inches tall, and just under 2 1/2 inches in diameter.
My comparison Sylvania bulb of 100 watts – regular tungsten – is 4 inches tall and 2 1/2 inches in diameter, so this compact fluorescent should fit in most fixtures.
The package says it should be in an enclosed fixture if it’s used outdoors, so it appears to be OK in a closed fixture.
The bulb starts gradually – you can watch the spiral warm up. It is quiet – no buzzing.

Light quality/color: Good
I have had this in use for a long time. Years? Color goes well in the living room.
Size
Total height is 6 inches, diameter is 2 1/2 inches. Fits in our lamp – barely.
Comments
The plastic housing is turning brown on top. I will revise this post with wattage and heat.
The amount of light is acceptable for the wattage. Subjective measure of course.
Starts like a bulb should. Again not scientific, but not noticed one way or the other.

Nice light, that works in your home; long life, not too toasty. I’ll be measuring temperature and voltage soon with an infrared thermometer, and a Watt Meter.
Bad Bulbs
Glaring blue green. Rotten for indoors. Hot. A waste of money, because you didn’t buy them for the garage.
