It's more about the k rating than the w rating :idea:

Ah... That varies on the coating on the outside. My advice? Take pictures of both illuminating a white board and look at how much of a hue adjustment you need to get the raw file to pure white (on a calibrated monitor) in adobe camera raw. That should tell you the colour temp.

Aside from the fact the OP's question was vague, you need to know incandescent and CF bulbs are two entirely different animals, it's just not the coating on the outside.

For the sake of lighting for photography we can ignore the energy necessary to produce x amount of watts. What is important is the color or k rating of the bulbs.

Most incandescent are too yellow (2600k), the CF's also come in lower K ratings but are available from 4100k - 5500k which produces a nice white light.

65 w CF = 200 w incandescent
40 w CF = 150 w "
26 w CF = 100 w "

These ratings are for the twisty style bulb.

With these bulbs I have not found it necessary to do a custom white balance.

Here's an interesting chart listing the K ratings of various sources...
