These Compact Fluorescent Full Spectrum Lamps (bulbs) are the highest quality available today.
Their Compact spiral design allows installation in almost all light fixtures. And because they are Fluorescent, they are extremely energy efficient. But the feature that makes them so different from most CFLs is that they are Full Spectrum or Daylight bulbs. This means that the color of light is comparable to the color of the sun.
Most CFLs look dull and don't light up a room as well as a standard incandescent bulb. These are much brighter, you can see the difference.
