From Incandescents to LEDs:

Watt’s the

Deal?

Page 3: Watt's The Deal with Lightbulb Options?

Another valuable presentation from the world’s leading

green building network:

Page 4: Watt's The Deal with Lightbulb Options?

Incandescents are out because…

1. They’re inefficient.

Page 5: Watt's The Deal with Lightbulb Options?

Incandescents are out because…

1. They’re inefficient.

2. Alternatives aren’t expensive.

Page 6: Watt's The Deal with Lightbulb Options?

Incandescents are out because…

1. They’re inefficient.

2. Alternatives aren’t expensive.

3. The federal government says so.

Page 7: Watt's The Deal with Lightbulb Options?

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.

Now, on to the BIG decision…

Page 9: Watt's The Deal with Lightbulb Options?

CFL or

LED?

Page 10: Watt's The Deal with Lightbulb Options?

First, some definitions:

• Watts: energy input

Page 11: Watt's The Deal with Lightbulb Options?

First, some definitions:

• Watts: energy input• Lumens: light output

Page 12: Watt's The Deal with Lightbulb Options?

First, some definitions:

• Watts: energy input• Lumens: light output• Footcandles: actual level of light to

reach surfaces

Page 13: Watt's The Deal with Lightbulb Options?

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

Page 14: Watt's The Deal with Lightbulb Options?

Next: Are you over illuminated?

Page 15: Watt's The Deal with Lightbulb Options?

Check the Illuminating Engineering Society (IES) Lighting Handbook here for recommended lumens for your

space type.

Page 16: Watt's The Deal with Lightbulb Options?

One more thing: Do you have the right ballasts?

Page 17: Watt's The Deal with Lightbulb Options?

Swap out outdated magnetic ballasts for electronic

alternatives and increase energy savings by 30%.

Page 18: Watt's The Deal with Lightbulb Options?

Swap out outdated magnetic ballasts for electronic

alternatives and increase energy savings by 30%!

Now, back to the big decision...

Page 19: Watt's The Deal with Lightbulb Options?

Traditional fluorescents have a higher efficacy than LEDs, according to DOE.

Page 20: Watt's The Deal with Lightbulb Options?

But they are not good in especially cold temperatures, and some blow long before

their expected duration.

Page 21: Watt's The Deal with Lightbulb Options?

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.

Page 22: Watt's The Deal with Lightbulb Options?

LEDs are up to 90% more energy efficient and have a

longer lifespan.

Page 23: Watt's The Deal with Lightbulb Options?

But they are not effective in especially hot temperatures and can flicker if the correct dimmer

isn’t installed.

Page 24: Watt's The Deal with Lightbulb Options?

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.

Our best advice?

Consult a professional first to determine what light level you

really need.

Page 26: Watt's The Deal with Lightbulb Options?

We happen to know some great ones, like

Bruce Wilson in Coopersburg, PA!

Or browse our entire growing membership here.

Page 27: Watt's The Deal with Lightbulb Options?

Then, if you can and the location is appropriate, invest

in LEDs.

Otherwise, find a comparable CFL substitute.
