curring for the past three years, which is something … be er vaguely conscious than completely unconscious, I sup‐
pose. This is also a big leap from last year when 52 percent of Americans were “generally aware” of the situa on. In
2008, that number was 21 percent.
Similar to last year, brightness (92 percent), life span (87 percent), energy consump on (82 percent), and
price (82 percent) were among the chief concerns of those switching out incandescents for new bulbs. Respondents
also strongly favored light bulbs that are manufactured domes cally.
And this is interes ng: for the small number (30 percent) of respondents who claimed to own LEDs, only 11
percent of them own stand‐alone LED bulbs meant to replace standard incandescents — a majority of these LEDS
(55 percent) are in Christmas light form.
And in other incandescent phase‐out news, Home Depot, the world's largest seller of light bulbs, has created
an intriguing map that combines 2010 U.S. Census data and a year of combined LED/CFL sales informa on to spot‐
light the 10 largest markets for energy‐efficient light bulb consump on (per capita) in the country: Atlanta, Boston,
Sea le, and Pi sburgh all top the list as do Washington D.C. and two major metro areas in Florida.
The government website, Energystar.gov, provides the following informa on for consumers on the differ‐
ences and benefits of LED and Compact Florescent Lights (CFL).
What are LEDs?
LEDs, or light–emi ng
diodes, are semiconductor de‐
vices that produce visible light
when an electrical current is
passed through them. LEDs
are a type of Solid State
Ligh ng (SSL), as are organic
light–emi ng diodes (OLEDs)
and light–emi ng polymers
(LEPs).
How is LED ligh ng different than other light sources, such as incandescent and CFL?
LED ligh ng differs from incandescent and compact fluorescent ligh ng in several ways. When designed well,
LED ligh ng can be more efficient, durable, versa le and longer las ng.
LED ligh ng products use light emi ng diodes to produce light very efficiently. An electrical curr
