Warm Compact Flourescent Lights (CFLs)
My roommate and I were very displeased with some CFL bulbs we tried over the last month. One was an expensive Philips Day-Light bulb which was just plain too whitish/blueish. Yuck. But on a recent trip to Home Depot I was able to spot on Nvision’s packaging a yellow to blue spectrum indicator showing that if I wanted the warm/yellowish incandescent color I needed to buy the “soft white”.
It’s great. No one believes it’s fluorescent.
Here’s some oneline help for buying the CFL you want:

Here are some specific numbers:
Between 2,700 and 3,000 degrees Kelvin—the color matches the typical incandescent light. The lower the temperature, the warmer the light. Higher temperatures mean cooler, more like sunlight. 4,000 degrees Kelvin equals a “cool white” incandescent bulb. source
