I recently returned some compact fluorescent light bulbs (CFLs) to my local hardware store because they were too dim and white. The traditional bulbs they replaced had been much warmer and brighter, and I prefer this kind of light.
Martha Stewart Living had an article in their September 2008 issue that highlighted the differences of all the CFL options. I highly recommend consulting this guide before you head out to purchase some new bulbs. I wish that I would have first consulted the guide. Here are some the recommendations they offer:
Table and floor lamps: Compact fluorescent in warm white.
Some general tips on color size and shape:
Energy-saving bulbs have adopted the shapes, sizes, and appearance of traditional bulbs, making it easier to phase them in.
When in doubt, opt for a warm-white CFL, 3,000 degrees Kelvin or lower. It has the color quality most associated with traditional bulbs.
This color temperature is best avoided. It washes out skin tones and makes reds, oranges, and browns look muddy.
In general, you should use a daylight bulb only in a reading or task light. The cool, bright tone makes text jump off the page.
