Switching over to CFL light bulbs can be a bit startling. First there’s the cost. You just have to remind yourself that they’re going to last A LOT longer than regular incandescent bulbs and use less energy to get over that one. Next is the color. When CFLs first came out, they emitted a fairly harsh blue light. Luckily, now there are a variety of CFLs on the market including ones that produce a softer, more incandescent light.
Kelvin Ratings and Color
Basically, a bulb’s Kelvin rating will tell you what kind of light it will produce. For instance, bulbs rated at 3,000° K and less will produce a warm or soft white, much like the familiar incandescent color. Bulbs rated at 4,000° K start to get a little cool, meaning they throw a slightly bluish hue. Bulbs rated at 5,000° K are perceived to throw daylight light and are the brightest and bluest of all CFLs.
