PWP wants you to replace your old incandescent light bulbs with energy-efficient compact fluorescent light bulbs (CFLs) and/or light emitting diode bulbs (LEDs).

THE GOAL: All 53,000 Pasadena households switch to at least 10 energy-saving bulbs -- our city will eliminate over 10,000 tons of carbon dioxide emissions every year!

THE PLEDGE: Make a pledge to switch to 10 energy-saving bulbs, tell 10 Pasadena friends to do the same, and help Pasadena eliminate over 10,000 tons of carbon emissions every year.
Pledge here!

THE KIT:  Between August and September 2008, every household in Pasadena received a Power of 10 Challenge energy-saving starter kit from PWP. Inside the kit were two free CFLs, a recycling pouch for safe disposal of CFLs, plus an order form for $75 worth of free CFLs.

Benefits of CFLs

CFLs come in many different styles and and fits for a variety of light fixtures in the home or business.

  • Energy-efficient - They use up to 75% less energy than regular bulbs.
  • Long Life Span - They last 10 times longer.
  • Safety - Bulbs are cooler to the touch.
  • Cost-Effective - Replace 10 of your old bulbs with CFLs and you'll save $530 or more on your utility bill over their life span.
  • Just as bright as your old energy-sapping bulbs!


Always recycle your used CFLs as electronic or hazardous waste because they contain a trace amount of mercury. NEVER throw them in the trash bin or blue recycling bin. Put them in a sealable "safe disposal pouch" (available at CFL drop-off centers) and bring them to an e-waste or hazardous waste collection center.

If you accidentally break a CFL, use precaution when cleaning it up: Read these Safe CFL Cleanup Tips.

Benefits of LEDs

The most common residential use of LEDs is for holiday lighting. LED holiday lights come in a variety of colors and festive styles, and can be easily found at most retail and hardware stores that sell traditional holiday lights.

  • Energy-efficient - They use 90% less energy than regular lights.
  • Long Life Span - They last up to 50,000 hours.
  • Stay Lit - One bad bulb won't shut off the whole string.
  • Safety - Bulbs stay cool and pose less of a fire hazard.
  • Sturdy Bulbs - Durable plastic bulbs are less likely to break than traditional glass bulbs.
  • Cost-Effective - In most cases, they pay for themselves in energy savings in the first year.
