watt's the deal with lightbulb options?
DESCRIPTION
In another great presentation from Poplar Network you'll discover exactly which lightbulb options are best for you. Incandescents, CFLs, LEDs - the options can be confusing! This straightforward guide from a LEED education provider will help you choose the wisest, greenest solution.TRANSCRIPT
Incandescents are out because…
1. They’re inefficient.
2. Alternatives aren’t expensive.
3. The federal government says so.
Incandescents are out because…
1. They’re inefficient.
2. Alternatives aren’t crazy $$$.
3. The federal government says so.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.
First, some definitions:
• Watts: energy input• Lumens: light output• Footcandles: actual level of light to
reach surfaces

Check the Illuminating Engineering Society (IES) Lighting Handbook here for recommended lumens for your
space type.
Swap out outdated magnetic ballasts for electronic
alternatives and increase energy savings by 30%!
Now, back to the big decision...
But they are not good in especially cold temperatures, and some blow long before
their expected duration.
But they are not good in especially cold temperatures, and some blow long before
their expected duration. You may have heard that CFLs spontaneously explode. This is
just an urban legend.Find detailed information here.
But they are not effective in especially hot temperatures and can flicker if the correct dimmer
isn’t installed.
But they are not effective in especially hot temperatures and can flicker if the correct dimmer
isn’t installed.For now, LEDs are a higher initial investment, too. But many
speculate that prices will drop in the coming 12 months.

Then, if you can and the location is appropriate, invest
in LEDs.
Otherwise, find a comparable CFL substitute.
