LED FAQs
- Why
LED's?
As a rule, LED bulbs use 90%
less electricity than standard bulbs. They have an unparalleled
even spectrum of light and have a lifespan beyond ten years.
LED's provide us the most efficient way to save energy and
conserve our natural resources. If LED's were implemented right
now universally, we would not need to build another power
plant. LEDs would actually eliminate the need for over 30
existing power plants!
- Do LED light bulbs contain
mercury?
No. LED bulbs do not contain
mercury. They can actually be recycled as they do not contain
hazardous substances and are manufactured without hazardous
substances.
- How do LED light
bulbs compare to CFL
bulbs?
Studies show LED light bulbs use
50% less energy than CFL bulbs and in many cases last 10 times
longer than CFL light bulbs. They are much more durable,
environmentally friendly, vibration and shock resistant and
offer excellent light quality, both indoor and outdoor.
- Do LED bulbs produce
as much heat as CFL or Incandescent
bulbs?
LED light bulbs emit much less
heat than a CFL or incandescent bulb. In many cases, you can
actually feel the temperature difference just by being near the
light. LED light bulbs will always operate at a lower
temperature than a CFL or incandescent which has immediate
benefits in reduced cooling bills in the summer months where we
are paying for our Air Conditioning to cool our offices.
- Why are LED lights
more expensive?
LED light bulbs use an actual
circuit board to operate and are made of electronic components.
Essentially, they could be considered an electronic device.
This technology continues to gain advantages almost daily. The
manufacturing and supply/demand of general lighting products
are gearing up today, and we will see costs continue to decline
as the adoption rate of LED Lighting increases.
- Is LED light a
different type of light?
Yes, LED light is said to be a
safer, healthier light. LEDs do NOT produce any sort of
ultraviolet radiation which causes fabric fading, color fading
in Art, carpeting and other soft goods. There is none of the
'buzzing' or 'flickering' that many people are sensitive to
with LED Lights. Residential and especially commercial and
industrial plants, stores libraries, galleries, and warehouses
can immediately benefit from LED Lighting.
- How long do LEDs for
general lighting really
last?
Remember, the longevity of LED
Lighting can be 100,000 hours. LED’s are Solid State devices
(SSL – or “solid state lighting”); they will not burn out. Life
expectancy for SSL lighting is upwards of 50,000 to 100,000
hours or more which means no maintenance costs for facilities
workers to replace lights. Over time, the cost of the
fluorescent or incandescent bulbs themselves can add up to a
significant savings when converting to LED’s.
LED lights are typically rated
to last about 100,000 hours. An incandescent light bulb is
rated for about 1000 hours. CFLs or Fluorescent Tube lights are
rated for 6-8000 hours. The product replacement cost math is
easy: (see chart below showing the next 10 years)

Did You
Know?
LED lighting offers excellent
light quality for both indoor and outdoor uses. It takes 50
incandescent light bulbs or 8 CFL's to equal the lifespan of 1
LED light bulb.
LED light emits 90% less heat
than a conventional bulb therefore producing more light than
heat and gaining maximum energy efficiency.
An LED light is the bi-product
of electricity jumping between two different alloys. This
produces a small amount of light and depending upon the alloys,
the color is dictated.
LED light is truly a solid state
light as there are no gases, no filaments and no moving parts
to fatigue.
Q. What are the main
benefits of LED-efficient lighting?
A: There are several key
benefits. Energy efficient LED
lighting just makes sense. Spread the word.
1. First,
it uses a lot less energy per unit of light output.
2.
Second, you'll save money.
Energy-efficient lighting lasts a lot longer, so be sure to
amortize your bulb costs over the expected life of the
bulb. In addition to the cost of the bulb, you should
include the cost of the labor to change the bulb. The
high-temperature bulbs increase the load of your A/C and
add to your cooling costs. If you have
to move retail racks or food preparation equipment, or
disassemble a luminaire, or find a ladder or lift, gas to
the store, the labor cost to replace a bulb or string of
lights can be high. There’s always the risk that the person
changing the bulb will break the luminaire or something
under it, so a 50,000 hour LED has a big advantage over a
2,000 hour halogen, for example, because the re-lamping
occurs much less frequently. Additionally, there’s a risk
the bulb will be dark for a while before being changed.
What is the cost to your reputation if your hotel,
restaurant or other business that has burned out lights?
With long-life bulbs, it just won’t happen as
frequently.
3. Third, since
energy-efficient lighting lasts longer, you’ll be
generating less trash for our landfills.
4.
Finally, you can feel good about using energy-efficient LED
lighting. You’re being a good corporate or private citizen
for conserving energy. Increasingly, people will notice
your energy conservation. And that’s great for your
reputation.
Halogens, a type of improved
incandescent lamp, are somewhat energy efficient, but are
losing ground to more energy-efficient technologies. They tend
to get really hot, too - halogens can hit over 350
degrees. Incandescent lights, the ones
Thomas Edison commercialized over 100 years ago, are
obsolescing rapidly. The bulbs are really cheap, but they don’t
last long and they consume far too much energy to be
competitive except in locations where they are rarely used,
such as an attic. They make decent heaters, but you wanted a
light, right? Especially if you have to pay for air
conditioning to offset the 90% heat output those 19th century
relics are throwing off.
The goal is to pay LESS for
lighting, including all the cost factors: the bulbs, the cost
of replacing the bulbs, gas to get them, the additional heat
and you will pay higher power-rent each monthly check you write
to the electric company.
Q. OK, but there's no
way it will make sense to replace a cheapo halogen cup bulb I
can buy on discount for $5 with an LED lamp that might cost
$45, right?
A: Wrong. It is less expensive
to use a $45.00 LED MR16 cup lamp than a FREE halogen cup
lamp that averages 3000 life-hours. That’s right!
If you used it 10 hours/day and pay 13 ¢/KW hour, you’ll save
$48.75/year (see our example) with the high-tech LED lamp and
that does assume paying someone to change and you to buy
another halogen bulb during that 3,650 hour
year. So you could take out halogen bulbs
you’ve already paid for (essentially free, at this point) and
save money by buying a $45 LED MR16. If the
light is inconvenient to change because of its location, you’re
even better off with the LED because it lasts so
long. If the bulbs still work, you’ll be
tempted to keep them, but remember; the biggest
cost of lighting is the energy consumed, not the
bulb.
