GROWTH, TRENDS & MARKET DRIVERS
Transforming Agriculture
with LED Lighting Solutions
By 2050, the planet’s population is
likely to rise from 7.7 billion today
to 9.7 billion. This growth, along
with rising incomes in developing
countries, is set to raise the global
demand for food by nearly 70%,
according to the Food and
Agriculture Organization.
In order to keep up, the agricultural
sector and farmers will need to
increase food production while
finding ways to cope with
challenges such as insufficient land,
droughts, and climate change.
The use of LED technology in
developing horticulture lighting
systems for food production is
playing an integral role in cutting-
edge farming practices that are
increasingly seen as potential
means to address food production
challenges. Today, LED-based
horticulture lighting is one of the
largest and fastest growing markets,
estimated to be worth $690 million
annually.
Since plants respond to light in an
entirely different way, horticulture
lighting is quite distinct from other
lighting applications. Light, in the
wavelengths useful for horticulture,
is called photo-synthetically active
radiation (PAR) and falls within the
400-700nm range.
Why LED Horticulture Lights?
“The systems that we are talking about are never going
to replace field crops. What we are going to do instead is
add another layer of crop production into the current
system, which is robust enough to survive climate change
and adds security to the food chain.”— Dr. Phillip Davis,
Former business manager at the Stockbridge Technology
Centre, UK (LuxReview)
Photosynthetic Photon Flux, or PPF,
measures the total amount of PAR
photons generated by a luminaire.
A higher PPF means the lighting
system is more efficient at creating
PAR.
THE LED ADVANTAGE
As researchers continue to establish
new findings around lights of
specific wavelengths and their
impact on different plants and
stages of growth, broad-spectrum
sources such as HPS lamps —
popularly used in greenhouses —
are being outperformed by
horticulture LED lights due to their
ability to produce PAR wavelengths.
LED-based substitutes for HPS
lighting, like Cree’s high power grow
lights, offer more than 50% PPF
efficiency compared to traditional
grow lighting.
A host of other compelling benefits
of horticulture LED lights makes it a
far-superior option for
supplemental lighting in green-
houses as well as vertical and
indoor farms that rely completely
on artificial light.
Control over spectral output
LED lights allow you to better
match spectra to plant’s need,
plus their luminosity can be
tailored to accentuate
production depending on plant
species and growth stage.
More precise targeting
With LED lights, you have
superior control over where the
light goes, which increases
efficiency, and reduces energy
consumption.
Lower radiated heat
LED lights can be placed closer to
plants, resulting in more dense
farms. This also lowers water
consumption.
Greater savings
The long lifetime of luminaires,
along with low energy
consumption and lower
maintenance costs, directly
translates to higher ROI for crop
producers.

While the benefits of using LEDs
seem obvious, adoption in the
horticulture space was previously
slowed by the challenges around
the cost of LED-based horticultural
lighting systems and the feasibility
of cultivating a limited number of
crop species using LED grow lights.
Fortunately, the market is changing
rapidly as suppliers, manufacturers
and product designers are
proactively developing and testing
new solutions to bring to market.
Cree®, for example, released a
family of small LEDs optimized for
horticulture, aimed at enabling
lighting manufacturers to reduce
the size of luminaires and lower
their system cost.
While mainstream adoption may
still be years away, we know this
market is poised for growth. It
represents many opportunities for
LED manufacturers, distributors,
installers, and the whole host of
energy professionals and solution
providers to deliver products that
are differentiated with new
functionalities to help farmers find
the ideal light recipe to maximize
yield of various types of crop
growth.
Most importantly, the focus is on
increasing ROI and reducing the
Total Cost of Ownership (TCO) of
end-users, whose goal is not just to
find the lighting system that
successfully mimics natural light,
but to do so at the lowest possible
cost.
The state of the horticulture lighting
industry is reflecting these trends
and several studies and survey
reports point to the growing market
span of LED grow lights.
LED ADOPTION AND MARKET GROWTH
“The high efficiency and
long-term reliability of Cree®
LEDs enables us to lower the
cost of the food we grow
and feed more people better
food."— Matt Vail, CEO at
Local Roots Farms, Los
Angeles, CA
A survey by the Lighting
Research Center (LRC) found
that:
48% of growers currently use
supplemental lighting to grow crops
55% grow crops under HPS lighting,
while 25% grow crops under LED
lighting
Cost, lack of relevant information,
and skepticism were listed as major
barriers to adopting LED lighting
Yet, they also found that the
majority of growers did not
know their monthly electrical
costs for lighting
64% of growers reported that they
pay a flat energy rate or a
combination rate (energy rate and
demand charges) for their
electricity. 20% of growers did not
know how they were billed for
electricity.

A 2016 Navigant Research study
estimated the worldwide shipments
of luminaires with LED lamps for
horticulture applications would see
a steadier growth compared to
other types, namely incandescent,
fluorescent, and high-intensity
discharge (HID) lamps [Figure 1].
A recent report by the market
research firm estimates the LED-
based horticultural lighting market
will reach $3.8 billion by 2027.
Another study by Reportlinker
predicts the overall horticulture
lighting market to grow from USD
$2.43 billion in 2018 to USD $6.21
billion by 2023, at a CAGR of
20.61%.
The market growth in horticultural
LED applications, according to
analysts at Navigant Research, is
helping lower installation costs for
luminaires, providing a stronger
incentive for growers to embrace
LED technology.
Another key factor influencing
market growth is the tremendous
leap in LED efficacies over the past
few years. For example, in 2014, the
best LED horticulture lighting
systems were at par with double-
ended HPS fixtures in terms of
efficacy. Today, LED-based lighting
systems are capable of achieving
45% more photon efficacies
compared to double-ended HPS
fixtures.

Farms of the Future
KEY APPLICATION AREAS
Greenhouse applications have been
the main drivers of the horticulture
LED lighting market for many years,
but emerging fields and new types
of farming are poised to lead the
future growth of the industry.
One of these reasons is indoor and
vertical farming. The greenhouse
use case for LEDs is mainly as a
supplementary light source to the
sun, whereas indoor farming uses
LED fixtures as the primary light
source.
More and more growers are
embracing these new farming
methodologies. Because of this,
they are more likely to depend on
LED-based horticulture lighting
systems for higher crop yields and
other benefits that LEDs offer.
While these new farming practices
are in the early stages and may be a
few years away from taking off,
they are poised to provide strong
growth potential in the next
decade. The 2017 Horticultural LED
Lighting report by Yole
Développement estimates emerging
applications and a horticultural
lighting market boom with a 16.4%
CAGR between 2018 and 2023
[figure 2].
Cree® and LEDiL® are two of the
leading brands supporting and
facilitating these changing trends by
bringing promising new products to
market that meet the needs of the
existing and emerging application
areas.
LED Horticulture Lighting
Applications
With a broad range of different spectra in multiple form
factors, LED lights are helping crop producers achieve
repeatable, predictable results across a wide array of
plant varieties and controlled environments. While
greenhouses were the main users of LED-based grow
lights, the application area of these lighting systems has
radically expanded, and continues to grow.

While traditional greenhouses have
been the most popular means of
cultivating in a controlled
environment, other techniques such
as vertical farming are increasingly
heralded as the next-generation of
modern agriculture — a future that
is not too far away.
Due to factors like decreasing
technology costs (LEDs in particular)
and rising demand for locally-grown
food, alternate growing systems,
particularly fully enclosed vertical
systems, are being preferred for
high density crop production in
urban environments.
A greenhouse differs from an
indoor farming facility by allowing
farmers to control growing
conditions like temperature and
humidity, while they are still able to
take advantage of light from the
sun. Indoor farming, on the other
hand, completely eliminates the
need for natural light. Therefore,
farmers can produce high density
crops in relatively smaller spaces,
while being able to precisely control
all factors that affect plant harvests.
Then, we have smart farming. The
available LED technology, coupled
with IoT-based intelligence, will
MODERN GROWING TECHNIQUES
“There is certainly a trend to try
and grow more crops and certain
types of food indoors for a variety
of reasons, such as pest control
and environmental control to
increase yields.”— Paul Scheidt,

enable future growers with sensor-
controlled lighting systems. This
technology will not only optimize
plant growth and yield, but also
automate the growing process by
eliminating the need for human
intervention.
We will discuss more about these
growing techniques in the next few
sections.

Greenhouses are currently the most popular and widely
practiced method of alternative cultivation across the
globe. According to Technavio's market research
analysts, the global greenhouse horticulture market will
witness a CAGR of more than 11% by 2022. And, it’s not
hard to see why — greenhouses have been around for
the most time and can be set up with a lower investment
in artificial lighting since they are not entirely dependent
on it. These are encouraging factors for growers wanting
to switch from conventional outdoor farming.
Greenhouses can be either soil-based or hydroponic.
Either way, they are designed to trap solar light and
humidity, creating favorable conditions for growing
various types of plants. Greenhouses protect plants from
external factors like the extremes of weather and dirt.
However, since greenhouse growers heavily rely on
sunlight, they give up the opportunity for better
production and higher quality yield that can be achieved
using artificial lighting.
Compared to greenhouses, a completely enclosed facility
like those used in indoor growing gives cultivators more
precise control over ventilation, CO2, light, and other
important factors to achieve the highest crop yield and
optimal growth. With an increased level of control,
challenges to production are easy to overcome.
The greenhouse use case for LEDs is primarily as a
supplementary light source to the sun, although artificial
lighting is increasingly critical during short days of winter
when sunlight isn’t available.
Greenhouses
“Where solar light is abundant, it should be
leveraged for crop growth. However, within 10
years there will be significant integration of LED
sources into all kinds of horticultural growing,
including closed spaces. As LED costs go down and
efficiencies go up it will be more compelling. It’s not
going to happen overnight, but you’ll see
differences in five years."— Dr. Cary Mitchell
Professor of Plant Physiology Purdue University
(GreenhouseGrower)

According to the Lighting Research
Center (LRC) Survey 2017, 37% of
growers used greenhouses with
supplemental lighting, while the
same percentage of growers did not
use supplemental lighting in their
greenhouse facilities. Even then, the
greenhouse applications have been
attributed the largest share of the
horticulture lighting market.
Greenhouses are more spacious in
comparison to other indoor
facilities, which is why they are
often used for tall crops. In this type
of facility, LED grow lights that serve
as a supplemental source are
installed above the plant canopy.
Cree® Solution for
Greenhouses:
Cree’s XP-E LEDs targeted at
greenhouses where there is more
room for larger light emitters.
The XP product lines deliver a
higher photosynthetic photon flux
density (PPFD) than a traditional
high-pressure sodium lamp, while
requiring only half the power. PPFD
measures the amount of light
between 400 nm and 700 nm,
which is the band that is useful in
plant photosynthesis.

The term ‘indoor farming’ is often used interchangeably
with vertical farming, but its scope goes much beyond
that. Indoor farms exist in many different forms — from
horizontal flood trays to vertical towers, warehouses to
basements, and micro-greens to heirloom tomatoes.
Technically, greenhouses can be considered as a form of
indoor farming too, but they differ primarily in the way
they depend on artificial light — indoor farms utilize
lighting systems as sole-source lighting as opposed to
supplemental lighting in greenhouses.
Indoor farms are mostly hydroponic, aeroponic, and/or
aquaponic, which is one of the reasons why this type of
facility uses less resources. Even though it needs to be
set up entirely with horticulture light systems, which
increases its CAPEX value, operational cost is relatively
low thanks to reduced irrigation, chemical and labor
expenses. Using LED-based grow lights brings down the
cost even further.
Indoor farms produce more per square foot, while
providing protection against the risks of weather
inconsistencies and pest access. Therefore, farming in
indoor facilities enables growers to achieve steady and
reliable results, allowing them to produce high quality,
pesticide-free crops all year round. These are some of
the factors behind the incredible growth of the indoor
farming industry.
According to findings in Agrilyst’s 2017 the State of
Indoor Farming report, indoor vertical farming
operations resulted in 2X revenue compared to
greenhouses. The report also found that indoor growers
yield 10–15 times more than outdoor farms.
Indoor Farming
“Indoor farms not only address the issue of arable
land, but as most of them employ precision
agriculture technology, the dependency on natural
resources like water and soil is also limited…indoor
farming is here to stay." —Indoor Farming: The
Doorway to Agriculture 2.0, Technavio Blog
11
Vertical farming is a specific kind of indoor growing
facility where many racks of plants are stacked vertically,
on top of each other — a feature which enables growers
to utilize the available space in the best way possible.
Stacks of crops can be integrated into structures like a
skyscraper, shipping container or warehouse, making
this type of facility ideal for urban farming. This is why
vertical farms are suitable for growing high density crops
in locations that are near to (or even within) a city.
This practice reduces supply chain costs, decreases fuel
emissions, and retains the freshness as well as nutritional
content of harvested fruits and vegetables till they reach
the consumer’s plate. These are some of the reasons
why vertical farming is being thought of as the gateway
into the next-generation of agriculture.
With lucrative business models of producing better,
fresher, cheaper produce at a fraction of the cost of
organics and with a similar footprint, vertical farms are
currently attracting millions of dollars in investments. In
fact, notable tech billionaires like Amazon CEO Jeff Bezos
and Alphabet Executive Chairman Eric Schmidt have
invested in a vertical farming startup, Plenty, which aims
to grow and sell chemical and pesticide-free fruits and
vegetables at costs that are competitive with organic
produce.
One of the biggest advantages of vertical farming is that
space isn’t a constraint, so farmers can grow crops even
in a square foot of area, yet benefit from a high yield.
Using Controlled Environment Agriculture (CEA)
technology, growers are able to have more control over
temperature, light, humidity, and other factors that
influence plant growth.
Vertical Farming
“Vertical farms, especially developed in cities, is
probably the most relevant solution we found to
produce fresh food and vegetables." — Pierrick
Boulay, technology & market analyst at Yole
(ElectronicsWeekly.com)

Because sunlight is not an option in
vertical farms, they receive 100% of
the necessary illumination from
horticulture lighting and, thus,
require fixtures of intensity higher
than what is needed for
greenhouses. Because of this,
vertical farming is poised to become
the biggest driver of LED-based
grow lights.
Lighting fixtures for these facilities
are typically smaller, enabling
growers to have fine-tuned control
over the light that individual plants
receive. Energy efficiency is critical
and so is thermal performance as
high-intensity lighting produces
more heat, which can negatively
affect plant growth.
Cree® Solution for Vertical
Farming:
Cree’s XQ-E line of vertical farming
diodes are the industry's smallest
high intensity LEDs and about 80%

Smart farming refers to tech-driven strategies for crop
production, which includes the use of data, high-
precision crop-control, and automated farming
techniques.
Analytics-driven precision agriculture enables growers to
make the best possible production decisions while
connected devices and IoT technologies monitor and
automate daily operations, helping farmers overcome
bottlenecks to production such as droughts and other
weather inconsistencies as well as pest management.
Having access to real-time data enables growers to
quickly identify and address problems, improving their
overall yield.
Smart farms monitored using IoT sensors managed by AI-
based data platforms could cut down the need for labor,
creating cost savings for farmers. Experts have estimated
that smart farming could be as much as 50% more
energy-efficient than other indoor growing environment.
A report by BIS Research estimates the global smart
farming market to reach $23.14 billion by 2022, rising at
a CAGR of 19.3% from 2017 to 2022. The market growth
is primarily attributed to rising consumer demands, need
for higher crop yield, the growing penetration of
information and communication technology (ICT) in
farming, and the need for growers to become climate-
smart.
Growing techniques in highly controlled indoor
environments is yet another area that is taking
precedence in the smart farming landscape. While
indoor cultivation methods help to produce the optimal
yield and plant quality, the use of analytics can help
growers accurately identify the different factors affecting
the harvest.
Smart Farming
“As we demand more and more from our farmers,
harnessing IoT technology for smart farming
appears to be the only conceivable way they’ll be
able to succeed. With a world population projected
by the United Nations to be 9.8 billion in 2050 and
11.2 billion in 2100, IoT in agriculture is an absolute
necessity.”— Josh Garrett, president and co-founder
at MOBI (TechTarget)

Intelligent LED systems are the ideal
lighting partners for smart farming
facilities. As such, smart grow lights
are being touted as the most value-
added internet-connected lighting
application in existence. These LED
lighting systems go beyond the
usual benefits of enhanced produce
quality and yield in controlled
environments. For example, even
the best grow light recipes need to
be accurately tweaked according to
the stage of the plant’s growth. The
intelligence and maintenance
capabilities of the smart grow lights
combined with sensors can
efficiently handle such tasks
without any human intervention. It
will not only make indoor growth
facilities more competent to fulfil
rising demands, but also create
opportunities for unprecedented
cost savings. While today, only a
fraction of these capabilities have
been explored, the possibilities are
endless.

OPTIMIZE YOUR INVESTMENT WITH THE RIGHT OPTICS
Uniform light and spectral distribution are imperative to raise high-quality, healthier,
crops with better production. The right optics help focus light energy on the plants
resulting in greater photosynthetic photon flux density (PPFD) using less power.
Furthermore, optics help growers achieve higher crop yields, while shortening the
growing cycles as well as reducing luminaire bill of material costs.
LEDs also have lower radiated heat, which means luminaires can be placed closer to
plants, allowing for more dense farms and reduced water consumption. This also offers
another vital advantage: sustainability. LED luminaires have a much longer lifetime
compared to traditional light sources, resulting lower maintenance costs.
The key questions to ask when designing horticultural lighting are:
• Does the light generate enough and the correct ratio of photons?
• Are the valuable photons going where they are needed?
• How efficient is the luminaire at generating photons?
With the right optics, LED light can be focused on the plants, without waste.
Narrow beam angle:
Gives a higher PPFD (for plants that require deeper penetration of light inside the foliage)
Wider beam angle:
Potentially lower PPFD but can be compensated by lowering the luminaires
Potential cause of shadowing problems
Lower foliage penetration
Asymmetric beam angle:
New possibilities - vertical plane, off-plant installations

levels (in 3 kW increments up to 12 kW in small rack or 24 kW in large rack)
• Highly flexible input (180-528 Vac, single or 3-phase) and outputs (12-1000 Vdc)
allows high voltage distribution, saving copper wiring costs
• Intelligent current and voltage source control (local or via Internet) eliminates
the need for individual luminary drivers
• Digitally controlled loop compensation eliminates bothersome flickering
throughout entire operating range
• Cloud-based GUI allows simple user customization of lighting profile dashboards
BEAT THERMAL CHALLENGES IN HORTICULTURE LIGHTING WITH NMB
Effective heat management is critical in indoor farms and controlled growth
environments. While LED luminaires generate less heat compared to HPS lamps, cooling
fans help to reduce overall heat even further. For horticulture lighting systems in
particular, the benefits of active cooling include a decrease in radiant heat directed at the
plants, reduction in size of LED fixture, lesser cost, better light output, and longer LED
lifetime.
NMB Technologies offers the only series of cooling fans that have achieved IP69K rating,
offering the highest proven protection available against closed range, high temperature,
high pressure spray-downs. They are available with a new metal casing with high
reliability in high temperature, plastic magnet, and if desired, stainless NMB bearings with
ceramic balls.
