We have the n:Vision (by TCP) brand of this bulb in warm/soft white. This little CFL just sips electricity - just 9 watts! It is perfect for those lamps that are smaller and typically call for a max of 40w bulb. Gives off plenty of light, and with good color tone. No flicker, hum, or buzz.
These are pretty good CFL bulbs for your home, they do take a few minutes to reach full brightness, but they turn on right away, last forever and use very little electricity, plus they're not too terribly expensive if memory serves.
