What does LED stand for?a. Light Electronic Diodeb. Laser Exuded Directionallyc. Light Emitting Dioded. Lower Electricity Demand

Answera. Light Electronic Diodeb. Laser Exuded Directionallyc. Light Emitting Diode

d. Lower Electricity Demand

Early LEDs were often used as indicator lamps for electronic

devices, replacing small incandescent bulbs.

Originally, one common use for LEDs was digital clocks.

Now they’re used everywhere,from street lights to display cases

to offices & warehouses.

How can LED lights increase your health & safety?

a. Fewer headachesb. Fewer accidentsc. Improve your skind. A & Be. B & C

Answera. Fewer headachesb. Fewer accidentsc. Improve your skin

d. A & Be. B & C

LEDs have been shown to cause fewer headaches, due to reduced

glare, hum and flicker.

LEDs help reduce accidents in 2 ways.

First, because they don’t need to be changed as often, you spend

less time up on ladders.Second, they emit

better, more consistent light, making it easier to

see and avoid danger.

In which of these places CAN you use LEDs?

a. In hospital patient roomsb. On a farm where livestock is

housedc. In grocery store refrigerators

and freezersd. All of the above

Answera. In hospital patient roomsb. On a farm where livestock is

housedc. In grocery store refrigerators

and freezersd. All of the above

LEDs emit less heat, making them even more cost & energy

efficient in grocery store refrigerators and freezers...

Because the cooling units will also use less energy to counteract the

effects of heat coming from the lights.

LEDs are more effective & efficient for use in livestock

housing where longer hours of

lighting are needed.

The durability & reduced heat output also make LEDs safer

(no toxic materials when broken and

reduced risk of fire.)

How much mercury is there in an LED bulb?

a. 0 mgb. .03 mgc. 2.1 mgd. 3.5 mg

Answera. 0 mg

b. .03 mgc. 2.1 mgd. 3.5 mg

LEDs contain NO mercury.In 2008, nearly

300 million compact fluorescent bulbs were sold, each containing

about 5mg of mercury.

When you add it up...

That’s the equivalent of 3,306 pounds of mercury, each year, in our homes,

and eventually in our landfills.

How much money could we save in energy costs

each year if the entire U.S. converted to LEDs?

a. $900 millionb. $250 billionc. $845 billiond. $16 trillion

Answera. $900 million

b. $250 billionc. $845 billiond. $16 trillion

Yes. That’s billion, with a “B”.Every year.

Which lamps function at peak efficiency in

subzero temperatures?a. Metal Halideb. High Pressure Sodiumc. Light Emiting Diodesd. Induction

Answera. Metal Halideb. High Pressure Sodium

c. Light Emiting Diodesd. Induction

Fluorescent lights are designed to operate at 77°F.

At lower temps they are less efficient and

give off less light. At very low temps

they won’t start AT ALL.

Because LEDs are electronic light

instead of gas, they turn on & off

instantly, at full capacity, regardless of the temperature.

If every American home replaced 1 light bulb with 1 LED bulb,

we would save enough electricity to power how many homes

for 1 year?a. Half a million homesb. 1 million homesc. 3 million homesd. 10 million homes

Answera. Half a million homesb. 1 million homes

c. 3 million homesd. 10 million homes

We would save about $680 million in annual energy costs...

and prevent 9 billion pounds of greenhouse gas emissions a year...

That’s equivalent to reducing the emissions from roughly 800,000 cars, each year.

By the end of 2014, which of these incandescent light bulbs will manufacturers be prohibited from making or importing?a. 100W bulbsb. 75W bulbsc. 60W bulbsd. 40W bulbse. all of the above

Answera. 100W bulbsb. 75W bulbsc. 60W bulbsd. 40W bulbse. all of the above

This is a result of the 2007 Energy Independence & Security Act, intended

to reduce our energy footprint and dependence on foreign fuel.

You might still see some of these bulbs on the store shelves, as it isn’t illegal to sell current or leftover inventory, but

over time they will all disappear.

How many incandescent light bulbs can be replaced with 1 LED bulb?a. 7 bulbsb. 14 bulbsc. 42 bulbsd. 83 bulbse. C or D.

Answera. 7 bulbsb. 14 bulbsc. 42 bulbsd. 83 bulbse. C or D.

Incandescent light bulbs last about 1,200 hours. LEDs last anywhere

between 50,000 and 100,000 hours.That means you’d have to replace your incandescent bulb between

42 & 83 times before the LED bulb burned out.

That’s a lot of bulbs.

How does more light affect a lactating dairy cow?a. She needs to eat more.b. She produces more milk.c. She’s happier.d. She is sick less often.

Answera. She needs to eat more.

b. She produces more milk.

c. She’s happier.d. She is sick less often.

When cows get 16-18 hours of light

per day, they produce

approximately 5.1 pounds more milk

per cow.LEDs cost less to run,

and last longer, making it more cost effective to keep the

lights on longer.

True or False:You’d have to remodel to convert

your light fixtures to LEDs.

Answer

FALSE

LED lamps can be used in many existing fluorescent fixtures

with minimal retrofitting.
