Watt's The Deal with Lightbulb Options?

  1. 1. It’s true: As of Jan. 1, 2014, the US government has legally phased out all incandescent manufacturing and importing. Read more on the topic here.
  2. 2. or
  3. 3. First, some definitions: • Watts: energy input
  4. 4. First, some definitions: • Watts: energy input • Lumens: light output
  5. 5. First, some definitions: • Watts: energy input • Lumens: light output • Footcandles: actual level of light to reach surfaces
  6. 6. First, some definitions: • Watts: energy input • Lumens: light output • Footcandles: actual level of light to reach surfaces • Efficacy: ratio of light output to energy input
  7. 7. Next: Are you over illuminated?
  8. 8. Check the Illuminating Engineering Society (IES) Lighting Handbook here for recommended lumens for your space type.
  9. 9. One more thing: Do you have the right ballasts?
  10. 10. Swap out outdated magnetic ballasts for electronic alternatives and increase energy savings by 30%.
  11. 11. Swap out outdated magnetic ballasts for electronic alternatives and increase energy savings by 30%! Now, back to the big decision...
  12. 12. Traditional fluorescents have a higher efficacy than LEDs, according to DOE.
  13. 13. But they are not good in especially cold temperatures, and some blow long before their expected duration.

  15. 15. LEDs are up to 90% more energy efficient and have a longer lifespan.
  16. 16. But they are not effective in especially hot temperatures and can flicker if the correct dimmer isn’t installed.
