The new fast-track
to growth
Philips GreenPower LED toplighting

Philips GreenPower
LED toplighting module
Increase yield, optimize quality, and reduce costs
Philips is introducing a new LED solution for greenhouses called GreenPower LED toplighting
module. It can be used either as a direct replacement for traditional lighting systems or as an
energy-efficient supplement. Perhaps even more importantly, growers who were previously
unable to use lighting in their greenhouse can now take full advantage.
LED toplighting can even be used in greenhouses not suited to conventional lighting, thanks
to the significantly lower heat radiation.
• Proven recipes for different crops
• Proven for different growth characteristics
• Less heat radiation
• Ideal for low greenhouses
• Easy-to-install
• Energy savings

GreenPower LED toplighting offers all the proven benefits of LED technology and – as a complete solution
– much more besides. For example, Philips offers growers extensive support in the form of calculations and
lighting plans by technical experts, and cultivation advice from in-house plant specialists.
It also offers a choice of dedicated ‘light recipes’ – different combinations of spectrum, intensity, moment
of lighting, uniformity and positioning – that it has developed over many years of cooperation with
growers, universities, and research sites to optimize growth. These make it possible to steer specific plant
characteristics such as compactness, colorintensity branch development, flower stimulation, and more.

For every greenhouse
Philips GreenPower LED toplighting modules are the next step in the development and application of dedicated light
recipes to increase production and improve crop quality. With this introduction year round production is in reach for
every greenhouse grower. LED toplighting offer light levels typically ranging from 40-300 µmol/m2/s in a highly efficient
way. Philips GreenPower LED toplighting can be used either as a direct replacement for traditional lighting systems or
as an energy-efficient supplement. Perhaps even more importantly, growers who were previously unable to use lighting
in their greenhouse can now take full advantage: even growers with low greenhouse ceilings can now enjoy the proven
benefits of LED toplighting.
LED toplighting offer the following key benefits:
Less heat radiation
LED lighting produces significantly less heat than
conventional HPS lamps, so you can control your
greenhouse climate more accurately. The convection
heat that is still being produced can often help to save
on your gas bill. Less heat also means you can use light
more effectively, for example by increasing light levels,
extending lighting periods, or by using light on warmer
days without having to ventilate. Less heat also means
you can place the light source closer to your plants,
reducing light loss – so close in fact that you can now
use toplighting even in low-ceiling greenhouses.
Spectral versions
LED technology makes it possible to optimize the
light spectrum in order to stimulate photosynthesis
and growth in an effective way, and/or to steer plant
development and morphology. Five spectral versions
have currently been developed based upon years of
experience. The types with white light present in the
module are convenient if working light is needed.
Flexibility and focus
Philips GreenPower LED toplighting is in the form of
linear modules in order to ensure maximum flexibility
in designing light plans with various light levels and high

uniformity in combination with ease of installation and
low light interception.The modules’ compatibility with the
C-profile (reducing light interception) and the option of easily
creating head-to-tail continuous lines, or discontinuous lines
of modules with cables in between, make the system highly
flexible and suitable for many greenhouse situations. It is also
possible to make combinations with existing HPS installations
or to combine various spectral versions in one line.
LED technology enables a uniform and targeted light
distribution, thereby minimizing expensive light losses. And as
LED lighting does not require any heat-up time, you are free
to initiate different lighting strategies at any time. Also, unlike
other LED toplighting systems, GreenPower is air-cooled in a
passive way, so no investment in water supply and drainage is
required, as with water-based cooling.

Efficiency of LED toplighting system vs HPS systems

Longer lifetime
LED solutions last much longer than conventional light
sources – up to five times as long, so you will spend a lot
less time and money replacing them.

100%

Less energy
LED toplighting uses significantly less energy than HPS
systems, saving up to 20-46% at comparable grow light
levels (µmol/J).

Applications
Cut flower growers

Benefits of GreenPower LED toplighting in various segments
Most greenhouse growers can increase yield, optimize plant quality and reduce energy costs by

Highly efficient production, good-quality flowers
In the case of cut flowers, length, weight, vase life, flower color and uniformity
are important quality and production factors. All of these factors can be
influenced by the light recipe, often in combination with other climate
factors. Optimizing these in combination with effective use of light will boost
profitability for growers of crops like chrysanthemums, alstroemeria, gerbera
and roses.

replacing or supplementing their existing lighting with a GreenPower LED toplighting solution. And
because LED lamps produce very little heat in comparison to HPS lamps and so do not damage the
plants, even growers with low greenhouse ceilings can now enjoy the proven benefits of toplighting.

Growers of high-wire vegetables
like tomato and cucumber

Growers of leafy vegetables and herbs

Year-round production, flexibility in use, efficient production, good quality
High-wire vegetables like tomato and cucumber need light for year-round
production in the most efficient way. The surplus of heat produced by
traditional light sources like HPS is often a restricting factor for using (higher
levels of) grow light in a greenhouse. With GreenPower LED toplighting this
is now an option, giving you more flexibility to light at times of higher outside
temperatures.

Tasty vegetables and herbs grown efficiently
Leafy vegetables are often grown at relatively cold temperatures, but they
grow very well under light. The growing systems for leafy vegetables vary
and therefore the light recipes can be optimized in different ways, adapted to
cultivation method, climate and cultivars.Various light recipes are available to
ensure optimal results in each situation: 100% LED or in combination with highpressure sodium in cold countries; one spectral recipe for a whole cultivation
period; or combinations of spectra and light sources during different stages of
the production cycle.

Strawberry growers

Potted plant growers

Early or year-round production, better-quality fruit
The strawberry production period can be extended to as much as year-round
by providing the right amount of light and the right temperatures. GreenPower
LED toplighting has the benefit of delivering efficient light while not creating the
heat load that could lead to lower-quality fruit.

Beautifully shaped plants with good leaf and flower color
Along with ornamental value, growth speed is the most important factor for
potted plant growers. Considerable energy is devoted to optimizing growth
speed via climate and growth regulators. Light is another tool that can strongly
influence growth, and it can be very effective when applied in the right way.
The spectral versions of GreenPower LED toplighting offer the option to go
for more compact growth (and possibly use less growth regulator) but also to
choose the most efficient growth. LED’s lack of heat radiation enables better
control of the plant temperature, preventing stress and damage to leaves and
making it possible to apply higher light levels (e.g. for phalaenopsis, anthurium).

Propagators
Uniform and controllable production to realize the desired plant architecture
GreenPower LED toplighting enables a very uniform light and heat distribution,
resulting in uniform production. The various spectral versions help to grow the
plant architecture you want, e.g. for the rooting of young floriculture material in
an efficient way.

Specification
GreenPower LED toplighting module
The GreenPower LED toplighting module offers a combination of carefully selected bestin-class technologies developed to serve grower's needs.
Efficiency and efficacy
The integrated electronic LED driver has a superior
efficiency, thereby limiting total heat production and
thus increasing the amount of photon flux per watt of
input power. The thermal design to extract the heat
from the LEDs has also been optimized for guaranteed
long lifetime and minimal light output depreciation.
The LEDs themselves offer the highest performance
available at the market, and the optical design of the
module ensures that almost none of the light is lost.
All these factors combine offer a system efficacy of
typically 2.3 µmol/J.
Light output over lifetime
When switching to LED it is important to know
what the percentage light output is after the stated
lifetime. The rated lifetime as listed in the table
below indicates 25,000 hours. This means that after
25,000 hours the light output is still 90% of the initial
value. After this rated lifetime the module is still
functioning properly, and light output depreciation
will continue in a similar trend.
Integrated driver
Integrating the driver also saves a lot of installation
hassle; the module can be plugged to the 400 VAC
Philips GreenPower

mains grid and used right away. The shape of
the module has been chosen to match standard
40x40 mm C-profiles: with the accompanying
brackets, installing a module is a matter of seconds.
Installation time is further reduced by wiring the
mains wires through the module, allowing for
cable-free installation.
Thanks to the integrated connector in the end-cap
the modules can be simply interconnected
by installing them head-to-tail without having to
worry about the electrical interconnections.
Furthermore, the system is not only rated IP66,
but the sealing is also implemented in a robust
way, which not only allows easy cleaning with
pressurized water but also guarantees reliable
operation in humid environments.
Linear approach
The linear approach of the toplighting system also
ensures:
• minimal daylight interception
• optimal heat transfer from the module to the
surroundings
• high uniformity of light on the crop when using
continuous lines (head-to-tail).
