Gavita. The most powerful
lighting on the market
The front runner in lighting development
Gavita is the oldest specialised horticultural lighting company,
building on 30 years of accumulated knowledge and innovation.
In 1994 Gavita introduced their first professional GAN fixtures to
the Dutch market. Since then Gavita innovations have become
industry standards. Gavita Nederland introduced for example
the 600W HPS lamp in 1995, the famous internal reflector lamp
in 1998, Miro aluminium reflectors in 2002, the first (adjustable)
professional electronic ballasts in 2003 and recently in 2010 their
solid state Light Emitting Plasma fixture.
For greenhouses and indoor facilities we design lighting plans
using high-tech computer models. Our testing facility uses the
state-of-the-art Ulbricht integrating sphere for accurate light
measurements. Gavita tests and implements new technology,
such as plasma light and high frequency electronic ballasts.
Our innovative reflector designs offer the highest efficiency
in the market.
Gavita has developed into one of the leading authorities in the
area of assimilation lighting. Based in the Netherlands, Gavita
2
Nederland serves customers world-wide and our installations
range from 1 - 40.000 units per customer. As a development
partner of Philips, General Electric and Osram, Gavita designs
and produces state of the art electronic ballasts, high efficiency
reflectors and complete fixtures. The key values of Gavita are
customer service and product excellence. Always in the forefront
of technology Gavita is synonymous for innovation, quality and
customer satisfaction. Gavita comprises several companies
and joint ventures in Norway, The Netherlands, Canada and
the Ukraine.
With over 40.000 acres of greenhouses The Netherlands is the
greenhouse capital of the world. More than 60% of all flowers
world-wide are auctioned in The Netherlands at Flora Holland,
the third largest building in the world, 7 times the floor space of
the Pentagon. Also fruits and vegetables are big export products,
mostly grown in greenhouses using assimilation lighting: In 2009
The Netherlands exported more tomatoes than top producing
countries Mexico and Spain.

Gavita Holland bv
In 2009 Gavita Nederland entered the hobby/hydroponics market
as Gavita Holland bv, offering a selection of adapted professional
fixtures and a series of new products specifically aimed at the
hobby indoor grower. Gavita Holland maintains the same high
professional standards for this market, in product quality as well
as customer service. The products you find in this catalogue are
either based on our professional proven horticultural products
(the Pro line) or developed specifically for this market. Finally
you can use professional products that were not available before
to the hobby market.
Not only do we bring professional products to the market, we
also bring our accumulated knowledge with it. We organise
lighting seminars, product demonstration, e-learning and
support local initiatives and organisations that work towards a
sustainable approach to gardening.
Gavita Holland serves the market through a professional
world-wide network of committed distributors.
Lumens are for humans
Gavita Pro lighting fixtures have a higher output than any other
HID lighting product in this market. That’s 15 to 20% more light
for your money, every day you use it, 365 days a year.
It’s all about Photons
Photosynthetic Photon Flux
Many lamp manufacturers still specify the output of their lamps (illuminance) in
lumens, though this just specifies how we humans perceive the intensity of that
light. Our eyes are most sensitive to green light of 555nm, but plants are sensitive
to a much broader spectrum. So what is the right way to specify horticultural
lamps and how can you calculate with that?
Scientists discovered long ago that there is a relationship between the number of photons and
photosynthesis: It takes about 8 - 10 photons to bind one CO2 molecule. They also discovered
that there is only little difference in the effectiveness of blue or red light. So they defined a direct
relationship between the number of photons in the PAR spectrum and the photosynthetic potential
of that light.
PAR spectrum
For many years now professional researchers have used photon counts in the PAR spectrum
as a standard and the greenhouse industry followed very quickly. European horticultural lamp
manufacturers specify the output of their lamps in PAR photons per second. This is called
Photosynthetic Photon Flux (PPF) and is expressed in micromoles per second (μmol/s). This is the
accepted professional industry standard now.
Plants primarily use the light ranging from
400-700nm bandwidth (violet to far red).
The light within this spectrum is called
Photosynthetic Active Radiation (PAR). So
the spectrum of the light that plants are
sensitive to is much broader than what we
see. Using lumens, which are measured
according to what the eye is sensitive to, is
therefore not a correct representation of
the grow light properties of a lamp.
Calculating with micromoles
If you know the output of a lamp you can calculate how many photons will reach your crop based on
the lit surface and your reflector efficiency. The more photons the more potential photosynthesis.
For example, if your luminaire outputs 2000 μmol/s and you spread that light over a 2m2 surface
the average irradiation on that surface will be 1000 μmol/m2/s. This is what we call Photosynthetic
Photon Flux Density (PPFD). In practice it is a bit more complicated as you have to calculate
reflector losses and you have losses from wall reflection, but it gives you a much better indication
than using lux and lumens.
For more information about Photosynthetic Photon Flux please visit our website
www.gavita-holland.com where you will find more examples and in-depth explanation.

The Gavita Pro 600 SE is part of the Gavita Pro-line series, offering you the latest technology in a series
of rugged, professional state of the art fixtures, reflectors and electronic ballasts. The Gavita Pro 600 SE
electronic ballast works on 230V, but drives a professional high voltage electronic horticultural lamp.
The Gavita Pro 600 is the first 230V electronic ballast that powers the professional Philips GreenPower
400V 600W EL (electronic) lamp. This lamp has the highest PAR light output, improved spectrum and the
best light maintenance (>95% PAR light over one year of use). The lamp and electronics are developed
specifically for each other by Philips. This guarantees the highest PAR output as the electronic high
frequency ballast is finely tuned to the lamp for optimal output and light maintenance.
Having your ballast close to your lamp reduces the amount of EMI (RF interference). Complete fixtures
have the advantage of integrated wiring so their EMI is down to the minimum. In large greenhouses
there can be as many as 10.000 on one location only.

In horticulture we see that reflectors lose on average more than 5% of their efficiency per year due to deposits, dust
and oxidation. That is valuable light that will not reach your crop. As tests have shown it is almost impossible to clean
reflective material without damage, it is important that you use reflectors that are made of the best materials and,
if needed, can be replaced.
The Gavita HortiStar 600 reflector fixture comes with a replaceable Miro aluminum reflector that can be replaced
with the lamp still in the lampholder. The fixture is suitable for HPS/MH lamps up to 750W. The lamp cord terminal is
shielded by a metal housing. Depending on your application and ballast you can order the HortiStar optionally with a
lamp cord of choice to match your ballast output, enabling plug-and-play installation.

One of the best 1000W HPS lamps in the market is the double ended Philips GreenPower
Plus 1000W 400V EL lamp. Specifically designed for high frequency electronic ballasts it has a
connection at each side of the lamp (hence double ended), removing the need for a frame support
wire inside of the lamp. The absence of a frame wire eliminates any shadows in the beam. Instead
of vacuum it is gas filled which allows for a smaller arc tube, improving the optical control. The
Gavita HortiStar 1000 DE reflector is specifically designed for this type of lamp.

Gavita Pro 300 LEP/Pro 300 LEP AC Plasma Fixture
Growing in indoor conditions without sunlight not only requires a good climate, but also a good
quality light. Though one can grow successful under HPS alone, or a combination of HPS and
MH, it is still not the full spectrum our sun delivers. The Gavita Pro 300 LEP produces light with a
spectrum similar to that of the sun.
Plants have evolved under sunlight over millions of years. University studies have shown that
seedlings and cuttings grown under full spectrum plasma light develop much better than under
HPS or CFL light and produce more lateral branches. The dry matter increases up to 30% and
the plant structure is more even and better distributed compared to HPS. It brings your plant into
the best conditions for generative development. Depending on your crop you can either use only
the plasma light or a combination of plasma light and HPS for plants that thrive on red light for
generative development.
10
The Gavita Pro 300 LEP is a solid state horticultural plasma light fixture. There are no moving parts
in the fully sealed housing, improving the reliability. The light source is a LUXIM STA 41.02 LiFi
module which has a rated average life of 30.000 hours. The glass wide spectrum filter allows for
low quantities UVB light to pass while shielding you and your crop from UVC. The Miro aluminum
reflector generates an even square light pattern. The absence of heat radiation in the light allows
you to hang the lamp close to your crop, or to add the light without adding extra heat radiation to
your crop.
The Gavita Pro 300 LEP is available as a solid state closed fixture, or in an air cooled (AC) version
which requires forced cooling. The AC version is installed in a 150mm pipe, enabling easy
installation of flexible ducting.

Gavita DigiStar Remote Ballasts
The Gavita DigiStar ballasts have
ve been developed to drive a wide range of HPS / MH lamps. They
are manufactured using the highest quality components needed for the high output frequency. The
result is a very cool digital ballast with optimal output specifications, absence of acoustic resonance
with suitable lamps and a very long life. Output can be boosted up +10%.
Digital ballasts have a lot of advantages over traditional magnetic ballasts: They are more efficient,
adjustable, generate much less heat and provide a stable output regardless of the input voltage.
Using a magnetic ballast you will lose light when your mains voltage is less than optimal.
To build a stable digital ballast you need high quality components. This is especially the case if you
want to reach the high frequencies required to prevent acoustic resonance in your arc tube, which
can lead to premature lamp failure.
DigiStar ballasts are built using the highest quality components. This results in a ballast that
outputs a very high frequency (preventing acoustic resonance) but also a very cool ballast.
12
The DigiStar is cooler and performs at a much higher frequency than comparable A-brand ballasts.
The DigiStars are adjustable over a wide output range, enabling you to dim or boost your lamp.
With 10% boost on the 400 and 600W models you are guaranteed to generate the highest output
available.
To ensure a long lamp life we have built in soft-dim. When you adjust your output it takes 60
seconds to gradually dim or boost per step. This process is so gradual that your eyes won’t even see
the difference.
Multiple output power enables you to use different lamps with a single ballast: The 400W model can
be used for 250W and 400W lamps, the 600W model for 400 and 600W lamps.
The internal microprocessor ensures the highest possible output in any circumstance.

The TripleStar 600 can be adjusted to 3 different positions: Wide, medium or deep. You can hang your reflector high
above your plants in the deep position for better climate control or close and wide in tight spaces. For every position the
uniformity of the light is better than 90%. In set-ups with more reflectors you can adjust them asymmetrically: Wide in
the middle for more overlap and better uniformity and deep at the sides to direct the light down, away from the wall.
The TripleStar is a very compact and versatile reflector creating a better and more even light distribution in any situation.
The three Miro Aluminum reflector plates are replaceable, so you never have to replace your complete reflector again.
We recommend to change reflector plates every year. The lamp cord terminal is shielded by a metal housing.

Frequently asked questions
Why should I use electronic ballasts?
Why does the Gavita Pro 1000 DE use a double ended lamp?
There are many reasons why you should use electronic ballasts. First of all they are more
efficient, produce less heat, are completely silent and have protection circuitry built in. So
they are very safe to use. But more important is how they work with varying supply voltages.
Your 230/240V from the wall socket can vary substantially. It can be higher but often it is
lower than the specified voltage. This can be caused by long supply lines, industry in the
neighborhood, or high demand on electricity, etc. A magnetic ballast will have a reduced
output when the input voltage is lower than specified. An electronic ballast always adjusts
itself to an optimal output, regardless of the voltage that is supplied (within some limits of
course). An electronic ballast will adjust the output to the lamp during its lifetime. It has a
soft start which puts less stress on a lamp when starting it up. Many electronic ballasts are
adjustable, so you can adjust your output based on the climate circumstances, such as hot
summers, or the age of your crop.
The Philips GreenPower Plus 400V 1000W EL lamp is a very special lamp. If you compare it
to other 1000W lamps you will already see that the arc tube is quite small in comparison.
Also you will see it is exactly in the middle of the lamp, and there is no wire frame in the
lamp (which actually intercepts some of the light). The glass is not normal glass, but high
quality quartz glass. Everything in the design of this lamp is for better optical properties.
By having no wire frame you don’t have anything blocking the light, the double ended
mounting assures perfect positioning within the focal point of the reflector and of course
the quartz glass is very clear and very high quality. Why do we use it? It is the brightest
lamp in the market with the best optical properties.
What are 400 Volt lamps?
We know, it’s confusing. In horticulture we
use 400 Volt electrical installation instead of
230/240 Volt you have at home. Specifically for
these higher voltage installations we develop
professional ballasts and lamps that run
more efficiently at a higher voltage. So the
professional “400 Volt” lamps can not be used
on a standard 230V ballast. The Gavita Pro
ballasts however have a 230 Volt input circuit
but power the efficient 400 Volt lamps. So
finally you can use the efficient horticultural
lamps in a 230/240 fixture.

Why do you specify your lamps in micromoles and not lumens?
Lumens are for humans. Plants use a different spectrum. Scientists found out that using micromoles
is the best way to indicate the photosynthetic potential of a lamp. Therefore every horticultural lamp
manufacturer specifies the output of their lamps in micromoles. Lamps that are produced for general
lighting are specified in Lumens, according to the sensitivity curve of the human eye.
Why should I replace my
reflector periodically?
Why are the Gavita HortiStar reflectors so small?
Gavita reflectors work on a different principle than the common wings and large
reflectors. You get two sources of light from our reflectors: the direct light from
a lamp (about 1/3 of the light) and the reflected light from the reflector (about
2/3 of the light). The further you go from a lamp the lower the light levels. So
right under the lamp normally the intensity is highest. The reflector should be
able to compensate the lower light levels at the edges of the throw of the lamp.
The Gavita HortiStar reflectors do that by reflecting the light to the other side
instead of reflecting it downward. This enables us to create a smaller reflector
which is still very efficient and has a very uniform light pattern. The reflective
material is made from high quality Miro Aluminum. The total reflector efficiency
is 96%, which means that if the lamp outputs 1000 μmol/s a total of 960 μmol/s
is delivered to your crop.
Reflectors get dirty and unfortunately cleaning
them does more harm than good to a Miro
aluminum reflector. Dust, dirt and deposits
depreciate the reflector efficiency by as much
as 5% per year. So why would you only change
a lamp when 2/3 of the light that comes from
your fixture is reflected light? Replacing your
reflector is the cheapest way to get more light
on your crop. If you want to clean it then do
it very carefully with only a soft cloth. Never
use detergents, some vinegar might work for
calcium spots, but rinse with distilled water
after that to prevent spots. NEVER polish a
reflector, you will scratch the surface. But in
any case: a cleaned reflector will never be as
efficient as a new one.
