LEARNING OBJECTIVES:
An Introduction & The Pitfalls of LED Site &
Landscape Illumination
Participants will be able to:
1. Identify the five main light sources available for site and landscape illumination- Incandescent,
Fluorescent, HID (High Intensity Discharge), LED (Light Emitting Diode) and Induction and
evaluate which is most appropriate for a given application.
2. Determine the color in degrees Kelvin and CRI (Color Rendering Index) of light that applies to
the design parameters of a given situation.
3. Assess how “Green” or Sustainable the five main light sources are and compare and contrast
them to the cost and performance of LED fixtures and lamps available on the market today.
4. Evaluate and rank LED lamp and fixture technology by comparing the AC (Alternating Current)
and DC (Direct Current) options and applying the Energy Act of 2005 to site and landscape
illumination to determine the need to retrofit existing fixtures or adjust existing electrical
system requirements.
5 MAIN LIGHT SOURCES:
1. Incandescent
2. Fluorescent
3. HID:
* Mercury Vapor
* Metal Halide
* High Pressure Sodium
4. Induction
5. LED (Light Emitting Diode)
5 MAIN LIGHT SOURCES:
1. Incandescent Light
Common household &
commercial light bulbs and
quartz halogen.
Example: Incandescent Bulb
5 MAIN LIGHT SOURCES:
2. Fluorescent Light
Common household &
commercial light tubes &
C.F.L.s.
Example: Fluorescent Lamp
5 MAIN LIGHT SOURCES:
3. HID
(High Intensity Discharge)
Light
Common commercial
& industrial light bulbs
(Mercury Vapor, Metal Halide
& High Pressure Sodium).
Example: Mercury Vapor
5 MAIN LIGHT SOURCES:
4. Induction
Limited commercial/industrial
light bulbs (Internal &
External).
5 MAIN LIGHT SOURCES:
5. LED
(Light Emitting Diode)
Light
Becoming more common
commercially and
residentially. Technology is
changing daily.
Example: LED Bulb
COLOR RANGES OF LIGHT:
Each type of lamp emits it’s own color range for which individuals have become
accustom to over the years, positively or negatively.
COLOR RENDERING INDEX:
CRI is understood to be a measure of how well light sources render the colors of
objects, materials, and skin tones.
LUMEN/WATT RATIOS:
A measure of the efficiency, or, more properly, “efficacy” of a light source.
Efficacy is easily calculated by taking the lumen output of a lamp and dividing by the
lamp watts.
LAMP LIFESPAN:
An average time period a lamp will function at it’s potential.

COST COMPARISONS:
The following chart is based upon examples of site and
landscape illumination fixtures.
THE LED STORY:
What is an LED?
Rather than heating up wires or exciting a gas an LED emits light
by electronic excitation with very little heat generation.
Diodes are electrical valves that allow electrical current to flow in only
one direction, just as a one-way valve might in a water pipe.
When the valve is "on," electrons move from a region of high electronic
density to a region of low electronic density. This movement of electrons is
accompanied by the emission of light.
The more electrons that get passed across the boundary between layers,
known as a junction, the brighter the light.
THE LED STORY:
How an LED is made:
To make the semiconductor wafers, gallium,
arsenic, and/or phosphor are first mixed
together in a chamber and forced into a
solution. To keep them from escaping into the
pressurized gas in the chamber, they are often
covered with a layer of liquid boron oxide.
Next, a rod is dipped into the solution and
pulled out slowly. The solution cools and
crystallizes on the end of the rod as it is lifted
out of the chamber, forming a long, cylindrical
crystal ingot. The ingot is then sliced into
wafers. The different semiconductor materials
(called substrates) and different impurities
result in different colors of light from the LED.
AC VERSUS DC POWER:
AC Alternating Current
DC Direct Current
AC VERSUS DC POWER:
LED fixtures are available AC or DC & 12 volt &
120 volt.
DC LED’s are more efficient, but require drivers
to convert AC current to DC current. This
process generates heat which is detrimental to
the diodes and can reduce their lifespan.
The drivers can be combined within the bulb
assembly or separately & remotely.
Combined driver/lamps have issues with low
wattage due to the heat generated by the
close proximity of the drivers.
The DC LED lamps are fed with low voltage
power and the drivers are typically remotely
located. 120 volt power is brought to the
driver, but does not have to continue on to the
fixture.
FIXTURE SELECTION
To retrofit or to start anew?
There are TWO very different situations in the
marketplace.
First is converting an existing lighting system
from Incandescent, Fluorescent or HID to LED
by retrofitting the existing fixtures?
The lamp choices are limited due to the size
constraints of the existing fixture and the need
to combine the driver and diodes.
Second is installing a completely new LED
system? This requires all new fixtures and
wiring along with a location for the drivers.
The high cost and lack of lumen output of LED
retrofit lamps limits the conversion from
common lamps to LED.
FIXTURE SELECTION
Many factors influence the fixture
selection?
The intensity of light required.
The color of light required.
The beam spread of fixtures required.
The sustainability requirements.
The electrical system and codes required.
The budgetary requirements.
NOTE: The Energy Act of 2005 has essentially
banned Mercury Vapor & Fluorescent ballasts
in favor of CFLs and LED.
