Install compact fluorescent light (CFL) bulbs to save time, energy and money. ENERGY STAR qualified CFLs offer:

  • Long life
    Last up to 10 times longer than conventional bulbs. On average, CFLs are changed only every five to seven years.
  • Big energy savings
    Use 2/3 to 3/4 less energy than standard bulbs. Save up to $30 in energy costs per bulb over its lifetime.
  • Great performance
    Instant turn-on, quick warm-up and excellent light quality.
  • Cool operation
    Operate at lower temperatures, enhance safety and generate little heat.
  • Small size
    Many are no larger than conventional bulbs.
  • Many styles
    Styles for almost every light fixture.
  • Low cost
    Available locally for $1.50-$8. A CFL saves far more in energy costs than its purchase price.

CFL bulbs contain a trace amount of mercury (no bigger than the period at the end of this sentence). When your CFL burns out, please do not put it in the trash. There are convenient, free recycling options available in Fort Collins. Learn more about CFL failure and disposal.
