Default Cfl

We are using CFL nearly everywhere. Several kind of CFL exist :
  • The classic CFL emit a "standard" artificial light. May be noted 2700°K on package.
  • The "daylight" CFL emit a light closer to natural light. Usually noted 6500°K on package.
  • The spot CFL emit a narrow light, as classic spots.

Here are several examples :
  1. The classic CFL (2700°K)
    This one is a classic CFL consuming 21w (100w equiv.) and is replacing a classic 100w bulb, ie 79% saving.
  2. The "daylight" CFL (6500°K)
    This one is a "daylight" CFL consuming 20w (100w equiv.) and is replacing a classic 100w bulb, ie 80% saving.
    We are thinking about changing a few classic CFL with "daylight" CFL.

  3. The "daylight" spot CFL (6500°)
    The spots CFL are 9w (39w equiv.) and replacing 50w spots, ie 82% saving even if these are less efficient than other CFL. These spots CFL are "daylight" so even if the light is a little bit weaker (136w equiv. instead of 200w), the light quality is better.
