TODAY’S PRESENTATION

1.  What are LEDs? 2.  Why should I switch to LED lighting? 3.  How do I choose the right LEDs? 4.  The Rebate Process

Focus on 4 Main Topics

1. WHAT ARE LEDS?

LIGHT BULB EVOLUTION

Incandescent Edison Lights

1879 CFL

Compact Fluorescent

Lights 1976

LED Light

Emitting Diode 1995

!  1907: “Electroluminescence” was discovered, i.e. material lighting up when electric current is applied

!  1962: Dim red LEDs developed !  1971: Green, orange and yellow

LEDs developed, but still dim !  1993: Bright blue LED developed !  1995: White LEDs hit the market

LED TECHNOLOGY

A Brief History

LEDS – WHERE ARE WE NOW?

! From the awkward, large and funny looking bulbs of just a decade ago…

! Now widely used in !  Commercial and residential lighting,

computer monitors and televisions !  Headlights, indicator lights, brake lights,

traffic lights, street lights

! Price has dropped in 15 years from $200 per unit to only 5¢ per unit

Evolution of the LED bulb

2. WHY SHOULD I SWITCH TO LED?

LOW ENERGY USE AND LONG LIFE

! Typical Household Bulb !  Incandescent

!  CFL (Compact Fluorescent Light)

!  LED

Compare Incandescent, CFL and LED

60 Watts 1,200 hour lifespan (around 1 year of

average use)

13-23 Watts 8,000 hour lifespan (around 6-7 years

of average use)

5-13 Watts 50,000+ hr lifespan

(over 40 years of average use)

LOW ENERGY USE AND LONG LIFE

!  Incandescent !  60 watts * 4 hours/day * 365 days/year * $0.13/kWh

!  CFL !  13 watts * 4 hours/day * 365 days/year * $0.13/kWh

!  LED !  8 watts * 4 hours/day * 365 days/year * $0.13/kWh

Calculate the savings

Annual Cost 1 bulb = $11.39/yr 20 bulbs = $228/yr

Annual Cost 1 bulb = $1.52/yr 20 bulbs = $30/yr Year after year…

Annual Cost 1 bulb = $2.47/yr 20 bulbs = $49/yr

WHAT ABOUT THE COST OF THE BULBS?

!  22 standard incandescent bulbs "$22 !  3 CFLs " $6 !  1 standard LED bulb " $5-$10*

It takes over 20 incandescent bulbs to last as long as 1 LED

*not including available rebates from AMP

ENVIRONMENTAL IMPACT

! LEDs waste less energy as heat (which can also cause people to use their AC more!)

! LEDs don’t waste energy making light that is emitted in the “wrong direction”

OTHER BENEFITS

! Durable quality !  Don’t break easily !  Resistant to vibrations,

temperature and weather

! Come in a rainbow of colors

HOW DO LEDS COMPARE TO CFLS?

Comparison CFL LED

Work with most modern dimmers No Yes

Work in most enclosed fixtures No Yes

Can be turned on and off frequently without consequences

No Yes

Come on instantly No Yes

Sparkle in chandeliers or accent lighting No Yes

Emit UV light Some Almost none

Release Mercury if broken Yes No

HOW DO LEDS COMPARE TO HALOGENS? Comparison Halogen LED

Bright light that doesn’t fade Yes Yes

Operate on line voltage Yes Yes

Operate on low voltage Yes Yes

Good for landscape, desk lamps, chandeliers, accent lighting, etc.

Yes Yes

Bulb gets extremely hot to the touch Yes No

Longer life than incandescent About 2 ½ times longer

About 20-40 times longer

More efficient than incandescent By 10-20% By 80-90%

HALOGEN TORCHIERE LAMPS

! Very popular! !  Super bright, upward wash of light !  300-500 watts – lots of energy! !  Fire hazard – should be replaced

for safety

! Bright LED replacements are now on the market (3000 lumens)

Does anyone here have one of these?

3. HOW DO I CHOOSE THE RIGHT LED?

BUY BASED ON LIGHT OUTPUT & COLOR

Light Output = LUMENS


Light Output = LUMENS

8.5 watts

800 lumens


! Until 200 years ago, we spent most of our waking time outdoors, now it’s the opposite!

! We used to be exposed to different color light at different times of day

Light Color

Mid-day light is blue, a “cool color”

Evening light is orange, or “warm color”


! Until 200 years ago, we spent most of our waking time outdoors, now it’s the opposite!

! We used to be exposed to different color light at different times of day

Light Color

Moonlight is also a cool blue

! Light Color affects our hormone production


Light Color

Well-being, reduction of carbohydrate craving, impulse

control and a healthy stress response

Promotes SLEEP…

DOPAMINE SERATONIN CORTISOL

Cool White MELATONIN

Warm White


! Color is measured on the CCT scale (Correlated Color Temperature) in degrees Kelvin

Light Color

“Daylight” bulbs ≈ 6500K

“Cool White” bulbs ≈ 4500-5000K

“Moonlight” bulbs ≈ 4000K

“Warm White” bulbs ≈ 2700-3000K


Light Color

2700 K

LIGHT COLOR & HEALTH

! Tuning lighting to follow natural light patterns and our circadian rhythms !  Improves mood, productivity and sleep !  Studies in workplaces and schools show positive

results for daily light modulation

Human Centric Lighting

LIGHT COLOR & HEALTH

! You can buy and turn on different lights for different times of day !  Cool white or “daylight”

for mid day rooms !  Warm white for

evening rooms

! Use controls !  Tunable LEDs !  Computer app “f.lux” !  TV box “drift TV”

Human Centric Lighting

LIGHTING FACTS LABEL

! Which is which?

Additional Information

BULB TYPES

! Bulbs get a Letter and a Number !  Letter is for the shape !  Number is for the size, in 1/8’s of an inch

! Standard Lamp bulb is A-19

!  A means Arbitrary shape !  19 means 19/8”, or 2 3/8”

Shape and Size of common bulbs

A - 19

! Omnidirectional !  Only choose these if you need them

LEDs are directional by nature

!  A: Arbitrary (standard) shape

!  G: Globe

!  Ca: Candelabra (old fashioned chandeliers)

!  B: Blunt tip candelabra

SHAPE OF BULB


*

*not Energy Star certified

SHAPE OF BULB

! Directional – ideally suited to LEDs

!  MR: Mirrored Reflector – accent lighting

version so far, made by AXP

!  3-way bulbs !  Satco has a few Energy Star approved

3-way bulbs !  30/70/100 watt equivalent

Specialty Bulbs

LIGHT BULB BASES

!  Look at the base of your bulbs before shopping !  Note: bases are measured in millimeters

!  Take a sample with you to be sure it matches !  If you have GU24 sockets, you can always use an

adaptor to install regular screw base LEDs

Buy the correct base!

RECESSED LIGHTS

!  If you already have Recessed Lights, replace with LED Kits

! They come in all sizes, plus gimballed (light can tilt)

LED Replacement Kits

LIGHTING CONTROLS

!  Dimmers (read the fine print) !  Occupancy sensors !  Motion sensors

LEDs are compatible with all types of lighting controls

LIGHTING CONTROLS

!  Prism LED Desk Lamp !  Zigbee with remote or computer control !  Philips Hue uses phone or tablet App !  Amazon Echo is voice controlled

Hi-tech controls are now on the market!

ARE THERE BETTER BRANDS?

! Look for the Energy Star Logo

Many Brands – some familiar, some not

WHERE TO SHOP?

! Local !  Hardware stores

! Big Box Stores !  Home Depot !  Lowes !  Target !  Costco

! Online !  1000bulbs.com !  Amazon

LEDs are in all stores now

WAIT! BEFORE YOU SHOP…

RETHINK YOUR LIGHTING

! Ambient Lighting !  General, background light

! Task Lighting !  Kitchen counter, reading light,

desktop, workbench

! Accent Lighting !  Inside cabinets, on artwork

Light Layering


! Colors, surfaces and objects in the room affect the light quality !  Colors – light or dark !  Paint – glossy or matte !  Ceiling color and gloss level !  Surfaces – bumpy or smooth !  Materials – reflective or absorptive !  Mirrors & other reflective surfaces !  Items that block the spread of light

Enhance your desired light levels


! Turn off your lights during the day! !  Open blinds and curtains during

the day !  Consider light, airy curtains or blinds !  Install skylights or sun tubes

in dark spaces

Invite in the Daylight


Evaluate what you have now

Do I have enough task lighting or am I relying on ambient light for tasks?

Do I have the right lumens in my

spaces, or are my existing lights too bright or too dim?

Should I change the room or should I change the brightness of the bulbs?

Do I need omnidirectional or focused lights?


!  Test out LEDs before buying in bulk – there is lots of variation among incandescent, CFL and LED bulbs

!  Brightness detected by your eyes !  Color of light !  Appearance of colors in the room !  Spread of light

Explore your options

Incandescent (40W)

CFL (8W)

LED (5W)
