Most fluorescent bulbs are straight (linear) but some fixtures use circular (Circline) bulbs, while other fixtures use a U-shaped (U-bent) design. Fluorescent bulbs are available in many colors, or color temperatures, which create different light moods. Color temperature is a measure of the light bulb's color when illuminated and is measured in degrees Kelvin. The higher the number, the whiter and then bluer, or cooler the color. The lower the number, the more yellow, or warmer the color. The color of the light itself creates a mood in the lighted space.
