A Guide To Saving Money And Energy With Green Lighting
Compact fluorescent light (CFL) bulbs use 10% of the energy that a standard bulb
needs and they last 10 times longer. So, change your light bulbs. And if you want to know how to go green in a
bigger way with lights, check out the new LED bulbs. They can be twice as efficient as the CFL
Why You Should Choose An Energy Saving Light Bulb
When people refer to an energy saving light bulb, they are generally referring to a CFL or
Compact Fluorescent Light. A Compact Fluorescent Light Bulb is designed as an alternative to standard
incandescent light bulbs. Because of this, a Compact Fluorescent Light Bulb will fit into any standard light
socket designed for incandescent light bulbs.
An energy saving light bulb, putting out as much visible light as a standard incandescent, will
use less power and last longer. Even though energy saving light bulbs cost more than standard incandescent
light bulbs, they can save you as much as $30 over the period of their use. This is usually a substantial
savings above and beyond the increased cost of environmentally friendly light bulbs.
Of course, green consumers are more interested in the energy conservation achieved by using an
energy saving light bulb instead of a standard incandescent light bulb. This reduction of energy use,
however, is directly related to the cost savings of a CFL in comparison to incandescent lighting.
An energy saving light bulb is rated to last as much as nine to eighteen times longer than the
standard incandescent light bulb. They also use 75% to 80% less energy than their incandescent
Apart from using an energy saving light bulb, another source of green lighting are LED lights or
Light Emitting Diodes. These energy saving light bulbs are not really light bulbs at all but are
semiconductor light sources.
Until recently, LED lights have not really been used as a room lighting source because of strict
current and heat management requirements. Great progress is, however, being made in room lighting
applications for LED. An LED lighting source is longer lasting and uses less energy than the standard
incandescent light bulb. While they have presented cost issues for room lighting, the technology has been
causing their efficiency and light output to grow dramatically. This is expressed by the fact that a doubling
of output has been occurring about every thirty-six months since the 1960s.
Solar indoor lighting is a less known lighting option for the home. Its advantage, of
course, is that it uses solar power to create indoor lighting as opposed to power from off of the grid. There
have been many recent developments in the technology of indoor solar lighting, but one of the simplest forms of
indoor solar lighting is using portable lamps. These lamps are very similar to many of your typical outdoor
The indoor lights resemble a standard table lamp and can be placed in any location good for
collecting sunlight during the day. The lamps have small solar panels and collect the light and transfer the
energy to a rechargeable battery. At night, you turn on the light, using the battery to power it.
During the day, the solar panel collects the sunlight and recharges the battery. In this manner of operation,
indoor portable solar lamps are very much like green outdoor lighting, with which most of us are very familiar.
So, you can see that there are many types of energy efficient lighting systems out there to help
you generate light without using the power grid. Choose what best suits your current needs, from indoor solar
lighting to an energy saving light bulb, and do your part to create light while conserving energy.

Green Light Know How - Your Guide To Energy-Saving Light Bulbs
It's human nature. We're always eager to explore the newest product, especially the ones touted
to improve our lives. At the same time, we can be skeptical about new product technologies, and it can be hard to
decide what, and whether, to buy. This is certainly the case with energy-saving light bulbs. The Energy
Independence and Security Act, passed in December of 2007, started the clock ticking on the end of the inexpensive
and reliable incandescent light bulb. While it's true that a few bulb manufacturers have flirted with the idea of
nudging the energy efficiency of Mr. Edison's classic up enough to meet the law's requirements, it now appears
likely that U.S. consumers will need to convert to 21st century green light bulbs for most uses starting in
The mainstream media has been full of news about the coming light bulb revolution. In the last week of May
alone, both The Wall Street Journal and The New York Times ran high profile articles
addressing emerging trends on CFL (Compact Fluorescent Lamps) and LED (Light Emitting Diode) bulbs.
Since they cost more than traditional bulbs, most people buy energy-saving bulbs for two main reasons: they save
money in the long run and they're better for the environment. Specifically, because green light bulbs use much less
energy to produce the same amount of light, they reduce harmful gas emissions from coal-fired power plants (which
generate 50% of the electricity used in the United States).
So consumers should immediately replace all their incandescents with energy-saving light bulbs, right? Well, not
so fast. With lighting, quality matters especially in our homes where we gather, read, cook, eat, celebrate and
entertain. There's a perception that green light bulbs require sacrificing light quality. Don't believe it. Many
eco-friendly light bulbs cast soft, beautiful light. And no one should feel guilty about not switching out every
fixture containing a regular light bulb. Invest first in replacing the bulbs used most frequently. Savings will be
bigger and pay back periods shorter with this approach. And truth be told, there are scenarios where the best bulb
is the old-fashioned incandescent.
7 Keys to Choosing the Best Green Light Bulbs for Your Home or Office
Choosing from the many energy-saving light bulbs on the market today can be tricky. Gone are the days when all
that mattered was bulb wattage and shape.
By keeping these seven simple guidelines in mind, you'll be on a path to making smart decisions about what to
buy to meet your needs for energy-saving light bulbs in this new green age:
1. Pay more, not less - to save money in the long run, your new green bulbs should be able to
last for several thousand hours. If you buy the cheapest ones you can find, the odds are greater that they
2. Pick your spots - if a fixture is completely enclosed or is lit for less than 15 minutes
at a time and less than two hours a day, CFLs are a poor investment. Low energy, mercury-free halogens are
available that are worth a look in these situations. Wait until the existing bulb burns out (or hold onto it for
later use - see #6).
3. Nobody likes the blues - the bluish light cast by many fluorescent tubes is not appealing
to most homeowners. When buying CFLs and LEDs choose "warm white" or "soft white" labels for color that will look
pleasingly familiar. Energy-saving light bulbs labeled "cool white," "natural light," or "daylight" are blue-hued
and best for targeted applications like reading, task lighting and exterior fixtures, not for living areas,
atmosphere or accent lighting.
4. Dimming - most CFL and LED bulbs can't be used with dimmer switches. Look for green light
bulbs that are boldly labeled "dimmable." And while the industry has made great strides in recent years, most
energy-saving light bulbs do not dim as well as traditional incandescent bulbs. However, the big energy savings are
compelling for most homeowners. Making the switch to dimmable CFLs or LEDs in a busy family kitchen can be a real
money saver, including reduced cooling costs because neither type generates as much heat as incandescents. Last
point: the dimmer switch should be compatible with the green light bulbs you buy.
5. Let's do the twist - spiral or "twister" CFLs are the least expensive type. If these green
light bulbs are hidden behind a shade (though not totally enclosed), buying a spiral lamp will cut the payback
period versus glass covered CFLs.
6. Stay out of the closet - most closets need short bursts of instantaneous light. This is
usually true of powder rooms, basements, attics and garages. Among energy saving bulbs, CFLs in particular aren't
suited for this purpose. Traditional bulbs (or again, low energy halogens) are best in these scenarios until
something better comes along.
7. Innovative, intriguing, expensive - mercury-free LED bulbs are the future of lighting,
case closed. These green light bulbs use less electricity than even CFLs and they last 30,000 hours or more.
However, current prices per bulb are as high as $100, which means the payback period for most home-based uses is
too long to justify the price. If you are curious about this new technology and live in an area with high retail
electricity costs, you might consider LED replacement bulbs for one or two fixtures that get a lot of use (6+ hours
per day). Re-read Key #1 before you invest in these types of energy-saving light bulbs.
Ignore the Naysayers - Green Light Bulbs Are Here to Stay
One last point: mercury makes CFLs (and fluorescent tubes for that matter) work. Some serious people, including
syndicated columnist George Will, say we should avoid energy-saving bulbs for this reason. We disagree. Coal-fired
electricity generation is the largest contributor of mercury to the environment. Through reduced electricity
consumption, a single CFL will keep a lot more mercury out of the environment over its lifetime than it contains.
Still, releasing any mercury into the environment is a bad idea, so it's important to recycle CFLs when they stop
working. Recycling your used bulbs is getting easier all the time.
Green light bulbs are here to stay. This is good news for our wallets and our world because the cheapest,
cleanest kilowatt of electricity is the one that is never produced in the first place. Become smart enough to
buy the right energy-saving bulbs and don't look back.

Green Lighting - Useful Information
Good News on the Green-Lighting Front - Energy-Efficient
Light Bulbs Are Here to Stay
"Energy efficiency isn't just low hanging fruit, it's fruit
lying on the ground." - U.S. Energy Secretary Steven Chu, June 26, 2009
In December 2007, then-President Bush signed the Energy
Independence and Security Act into law. Among other things, this law opened the
door for energy-efficient light bulbs to gain market share in the U.S. However,
several commonly used lamp types were exempted under the Act. On June 26 of this
year, Energy Secretary Steven Chu announced a new set of efficiency standards for
General Service Fluorescent Lamps (GSFLs) and Incandescent Reflector Lamps (IRLs).
The rules will go into effect in the second half of 2012.
Since these two lamp categories represent 45% of total lighting
electricity consumption in the U.S., new energy-efficient light bulb rules are
significant. Vast amounts of electricity, and the harmful emissions attributable to
its production, will be saved over the decades ahead. This represents good news for
the American wallet and the environment we all share. Green light bulbs are here to
Green Light Bulbs for Downlight Fixtures
The rest of this article will focus on the opportunities to save
energy with state-of-the-art incandescent reflector bulbs, even before the new
efficiency standards go into effect.
The current minimum efficacy (in lumens per watt) standard for
PAR20 and PAR30, 120 volt, 75 watt IRLs (established in 1975) is 12.5. The new
rules that take effect in 2012 are applicable to the same lamps and increase the
minimum efficacy to 16.0 and 18.9 lumens per watt, respectively. This increase in
the standard represents a 28% and 51% increase in efficiency, respectively.
Eco-friendly light bulbs, which meet the newly announced 2012
standards, are already on the market (though they're not easy to find). The savvy
reader will suspect that a Compact Fluorescent Lamp (CFL) can easily surpass the
new efficacy rules for IRLs. And they'd be correct...CFLs typically produce 40 or
more lumens per watt, making them much more energy efficient than the more popular
halogen variety. But there's a catch: the light cast by CFLs and some other green
light bulbs, while satisfactory in the home or office, is inferior to halogen light
in terms of its ability to crisply render colors and fine details.
A Small Business Case Study: The Merits of Energy-Efficient
A small, green, retail business owner wants to reduce
electricity costs and carbon emissions without sacrificing the light quality needed
to properly showcase merchandise. In terms of switching to the right
energy-efficient light bulbs, what can the owner do now?
Single location, green home-goods retailer in central New Hampshire
occupying 300 square feet of space
36 recessed cans, mounted on 4 tracks, are used to light the store
28 cans contain green light bulbs (R30 CFLs) using 15 watts each for
8 cans, mounted in a track which lights an alcove occupied by a
paint-chip display for eco-friendly paints, contain PAR30 long neck
halogen lamps of 75 watts each (note that these 8 lamps consume 59% of
lighting electricity in the store).
Challenge: The owner wants to improve the energy
efficiency of the alcove lamps without sacrificing the crisp, flattering light of
the halogen lamps currently in use.
Recommendation: Replace 75 watt PAR30 long neck
bulbs with 48 watt GE Long Life HIR(TM) PLUS PAR30 long neck lamps. These
energy-efficient light bulbs yield output of 850 lumens, 90 lumens less than the
existing lamp. The owner found this reduction to be acceptable after testing the
new lamps for several days.
The new bulb produces 17.7 lumens per watt, making it 42% more
energy-efficient than the old lamp. Furthermore, it is 5% more energy-efficient
than Secretary Chu's just-announced standards for a 48 watt, 120 volt, PAR 30 (16.8
lumens per watt).
Finally, these lamps have a 40% longer life expectancy than the
old, a redeeming merit due to the typical higher price tags of energy-efficient
light bulbs. This advantage will reduce replacement costs and boost overall
Savings Forecast Using Green Light Bulbs
New Hampshire is a high cost electricity state with a commercial
rate of 15.6 cents per kilowatt hour as of March 2009 (citation: US Energy
Information Administration). The store owner estimates 2,000 hours of annual use
for these new energy-efficient light bulbs. At a retail price of $15.38 per lamp,
she expects to virtually break even after one year. And over two years, during
which time she would have had to replace the original 75 watt bulbs, she expects to
save $155, or 30%, using green light bulbs to light her alcove with the eight
The newly announced efficiency standards for GSFLs and IRLs are
welcome news for those concerned with reducing harmful gas emissions stemming from
electricity generation. And according to the Office of Energy Efficiency and
Renewable Energy, these green light bulbs will save U.S. consumers $1 to $4 billion
per year starting in 2012.
Manufacturers of energy-efficient light bulbs and their
forward-looking distributors are ahead of the curve however. It is therefore
possible for home and business owners with downlight fixtures to immediately start
phasing in green light bulbs, without sacrificing the great light quality they
enjoy from IRLs.

Green Lighting - Electricity That Drops Down To Light Up
ENERGY STAR gets the LED out
On September 30, 2008, ENERGY STAR put their Solid-State Lighting (SSL) Program into effect.
This means you can eventually buy ENERGY STAR qualified solid-state lighting. How soon? Manufacturers first need to
submit lighting products and get them ENERGY STAR qualified. Once done, you'll be able to pick them up for your own
We give you some notes to get you up to speed on solid-state lighting. When you hear solid-state
lighting, think LEDs (light emitting diodes). That's what we'll talk about . . .
How Do LEDs work?
Kind of like plunging in a roller coaster
LEDs differ from traditional light sources in the way they produce light. In an incandescent
lamp, a tungsten filament is heated by electric current until it glows or emits light. In a fluorescent lamp, an
electric arc excites mercury atoms, which emit ultraviolet (UV) radiation. After striking the phosphor coating on
the inside of glass tubes, the UV radiation is converted and emitted as visible light.
Electricity makes a wire glow in incandescent lamps and makes atoms emit ultraviolet light in
fluorescent lamps, which the tube then converts into visible light. So far, so good?
In an LED, electricity flows through a semiconductor chip's junction which has holes in it. The
electricity falls into these holes and releases light. Kind of like when you take a plunge in a roller coaster and
release a loud scream.
What Color Is Your Parachute?
You get different colors from LEDs depending on the material of the diode:
red - aluminum gallium arsenide
blue - indium gallium nitride
green - aluminum gallium phosphide
white - the red, blue, and green colors combined
Since there's no test at the end of this, forget about the high tech materials and remember red
+ blue + green make white. Oh, you know that already? That was easy.
What's So Different About LEDs?
Compare these against incandescent and fluorescent lighting:
Directional light emission - directs light where it is needed.
Size advantage - can be very compact and low-profile.
Breakage resistance - no breakable glass or filaments.
Cold temperature operation - performance improves in the cold.
Instant on - needs no "warm up" time.
Rapid cycling capability - lifetime isn't affected by frequent switching.
Controllability - compatible with electronic controls to change light levels and color characteristics.
No IR or UV emissions - LEDs intended for lighting do not emit infrared or ultraviolet radiation.
Where Can You Stick It?
You already can see some places where this will work for you ("cold temperatures" - refrigerated
In-cabinet accent lighting
Adjustable task lighting
Refrigerated case lighting
Outdoor area lighting
Step and path lighting
Spaces with occupancy sensors
Food preparation areas
Retail display cases
Art display lighting
And The Energy Efficiency:What's The Bottom Line?
Warren Buffet-sized returns on investment
The bottom line is looking up. In fact, you'll see quadruple-digit returns on your investment.
You may know that compact fluorescent lamps (CFLs) can last up to 10 times longer and use 75% less electricity as
incandescent lamps. Check this out:
Incandescent: about 1,000 hours
Comparable CFL: 8,000 to 10,000 hours
LEDs: 30,000 to 50,000 hours
Energy Efficiency: LEDs are comparable to CFLs, and getting better due to technical
improvements. LEDs look even better when you consider that 50% of incandescent or fluorescent recessed light is
lost inside the fixture; LEDs produce directional light. To you and me, that means no light loss and twice the
efficiency in those applications.
The Return On Your Investment: lasts 30 to 50 times as long as incandescent, while
using 1/8 of the energy. If that was your car, it would last 300 to 500 years instead of 10, and drive you from LA
to NY and back to LA on one $80 tank of gas. Then, in 300 years, your descendants later sell it on Ebay as an
antique and make a pot of money. Yep, Warren-Buffet sized investment returns.
