  • Compact Fluorescent Light Bulb

    Gonna go buy some compact fluorescent light bulbs today. My brother recommended them to me because they save lots of energy.  Bright White or Cool White, that is the question. I'll get both and experiment which color looks nicer.

    "In comparison to incandescent light bulbs, CFLs have a longer rated life and use less electricity. In fact, CFLs save enough money in electricity costs to make up for their higher initial price within about 500 hours of use."

    "CFLs are produced in varying shades of white:

    • "Warm white" or "Soft white" (2700 K - 3000 K) provides a light
      very similar to that of an incandescent bulb, somewhat yellow in
      appearance;
    • "White", "Bright White", or "Medium White" (3500 K) bulbs produce a
      yellowish-white light, whiter than an incandescent bulb still but on
      the warm side;
    • "Cool white" (4100 K) bulbs emit more of a pure white tone; and
    • "Daylight" (5000 K - 6500 K) is slightly bluish-white."

  • Thanks for the info. =P

  • ah yes- incandescent bulbs are TERRIBLE in efficiency. i always get emails from the environmental groups about them =P
    "soft white" and "warm white" sound so nice, but i tend to like the really white ones better...

  • I love them, but I hate the "color" they produce. Typically whitish or blue. It's very "cold" feeling, and office/businesslike, or like an operating room. You just can't set the mood with that kinda bulb. The daylight's are nice, but typically too bright to set the mood too. haha. Anyways, forget the mood, I'm poor!
