Around the globe, governments have passed laws phasing out traditional #incandescent light #bulbs citing reasons tied to #environmental #sustainability. This presentation explores the topic through the lens of the most commonly cited alternative options: compact fluorescent lamps (#CFL) and light emitting diode (#LED) bulbs. The presentation examines the advantages and disadvantages of each option and evaluates other sustainable lighting options, such as #halogen light bulbs. Included is a cost/benefit analysis and the importance of recycling both CFL and LED light bulbs. From multiple perspectives. you will learn how easy or difficult it is to transition to these alternatives and #recycling them once they reach end-of-life.

The Sustainable Evolution of the Light Bulb

  1. 1. (LALED,2013)
  2. 2. • Recently passed laws are phasing out traditional incandescent light bulbs • Alternative options include compact fluorescent lamps (CFL) and light emitting diode (LED) bulbs • In this presentation, you will learn how easy or difficult it is to transition to these alternatives from multiple perspectives • Advantages and disadvantages • Other sustainable lighting options • Cost/benefit analysis • Recycling (HomeDit,2013)
  3. 3. • “CFLs use about 75% less energy and last up to 10 times longer than traditional incandescent bulbs • Use about one-fourth the energy of traditional incandescent bulbs • Offer the same brightness and colors as traditional incandescent bulbs” (U.S. Department of Energy, 2013) (ThurstonTalk.com,2013)
  4. 4. • “[CFL] bulbs contain Mercury which is a highly toxic heavy metal which is especially dangerous for children & pregnant women” (EcoWise LED, 2013) (EcoWiseLED, 2013)
  5. 5. • “Compelling reasons to use LED bulbs: • Each LED light can last you 17 years • You‟ll save hundreds of dollars in electricity • You‟ll will be helping your health – and the environment • LED lights are not annoying • LED lighting is both extremely safe and durable” (LEDlightsandbulbs.com, 2010) (iJDMToy.com,2013)
  6. 6. • High upfront costs • Voltage is low so light isn‟t very bright • Tend to „dim down‟ after only 25% of their life span requiring you to change them more frequently (SparkNET, 2013) (UrbanVision, 2013)
  7. 7. • Halogen bulbs • Highly efficient • Provide bright, white light • Greater quantity of light and longer life as compared to regular incandescent bulbs • Downside: Become hot and generate heat (Bulbs.com, 2013; Lighting Fixtures & Ceiling Fans, 2004) (Public Domain)
  8. 8. • Least expensive option over expected lifespan • Use 11% of the energy of incandescent bulbs • Highly cost efficient (LEDBulbsandLights.com , 2010)
  9. 9. • Contains no mercury • No harmful UV emissions • No flickering and quiet in operation • Operates at a cool temperature • Use solid state components – extremely durable and safe (LEDBulbsandLights.co m, 2013) (LEDBulbsandLights.com , 2010)
  10. 10. (DrummondHouse Plans.com,2013) • LED bulbs: • Don't contain mercury • Aren’t considered a hazardous material so they may be safely recycled • Some stores and recycling centers will take them, e.g., Batteries Plus (Bellevue-Factoria) • CFL bulbs: • Contain mercury • Are considered a hazardous material • Most stores and recycling centers will take them for special processing
  11. 11. (Send Your Light Bulbs to Washington, 2013) • CFL bulbs need to be safer to use and easier to recycle • LED light bulbs need to become more affordable • Consumers often left with more questions than answers
