The reflector is one of the key elements of a
successful fixture. You can have the best ballast
and the best lamp, but without a good reflector you
waste a lot of light, every day you use it. Keeping your
reflectors in optimal condition is a must for good
results.
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 damaging them 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. As an
alternative, inlay reflectors are available. The fixture
is suitable for HPS/MH lamps up to 750 Watt. The
lamp cord terminal is shielded by a metal housing.
Installation is very easy with the two eye bolts.

A reflector should bring as much light to your crop as possible, and do this in a uniform way. The Gavita
HortiStar 600 does just that: It has one of the most efficient reflectors in the market with an efficiency
of 96 %. It is our most popular 600/750 W horticultural reflector. Using a professional quality fixture and
reflector has suddenly become very affordable.

PLEASE READ THESE INSTRUCTIONS FIRST BEFORE INSTALLATION
Congratulations on your purchase of the Gavita
HortiStar 600 SE reflector. We have done
everything to insure a long life and safe operation,
but the installation and use of the reflector is the
responsibility of the user. Incorrect use or
installation can lead to failure and damage to your
equipment. Damage to the reflector and attached
ballasts as a result of incorrect installation and
use revokes your warranty, so we recommend you
read this manual carefully before installing your
reflector.
Product description
The Gavita HortiStar 600 SE (SE for Single Ended lamp) is a state of the art adjustable horticultural reflector. It is
designed to hold the any E39 base HPS or Metal Halide lamp (including electronic high frequency HPS lamps)
between 400 and 750W. The high quality, hand-made HR96 reflector guarantees you the optimal light reflection
and uniformity.
The Miro Aluminum high efficiency reflector (HortiStar HR 96 600 SE) is replaceable without toolsand even
without unscrewing the lamp.
The high quality of the used materials and precision of manufacturing result in 96% reflector efficiency, which
means that 96% of all light exiting the fitted lamp will reach your crop.
The EU version is standard delivered without lamp cord, though lamp cords with Wieland or IEC plug are
available.
Scope of use
The Gavita HortiStar 600 SE is designed for plant cultivation and intended for climate room use. It is suitable for a
damp location but should not be used in wet environments or outdoor.
High Intensity Discharge lamps generate intense heat. Installation of HID lamps should be carried out according
to local installation and safety regulations.
Suitable lamps
The Gavita HortiStar 600 SE EU is equipped with a E40 lamp holder and is suitable for a 400-750W MH/HPS (high
frequency) lamp. Only use lamps that have been rated safe for open fixture use.
HID such as high pressure sodium and metal halide can not be used
without an appropriate ballast. Never try to connect a HID lamp
directly to mains.

Wiring the reflector
Be sure to comply to local installation regulations
When wiring HID lamps make sure that the lamp cord you use is tested and approved for high voltage (5 kV)
ignition pulses and high temperature. Always use stranded wired and use cable end sleeves to protect the
strands in the screw terminals.
Internal wiring diagram:
Do NOT connect any of the ballast outputs to the middle (ground) terminal. Connecting the ground wire to the
center terminal only provides protection when the ballast is also plugged into a grounded receptacle with a
grounded cord and plug. This is the recommended way of installation.
The white terminal wire (1) is connected to the center contact op the lamp holder, the black/blue terminal wire (2)
is connected to its thread.
If you have an electronic ballast there is normally no phase or neutral wire, so the way you connect the two live
wires to the outer terminals makes no difference. Our DigiStar models for example have two black wires in the
lamp cord. For fixed mounted magnetic ballasts it is advised to connect the phase wire to the center connection of
the lamp, so to the screw terminal with the white wire (1).
1. Locate the cover plate of the screw terminal and remove the 4 screws. One of
the screws has a tooth lock washer to make sure that the housing and the
plate are electrically connected. 
2. Feed the lamp cord through the opened cable gland. Do not tighten the cable
gland yet.
3. Make sure the screw terminals are open and insert the cable ends completely
into the screw terminals, tightening them with a screwdriver. Connect the
yellow/green ground wire to the middle terminal which is connected to the metal housing, the other two (live)
wires to the outer terminals. Electronic ballasts usually do not have a preferred way of connection the wires,
but the left (white) wire goes to the center contact of the lamp holder.
4. Before you replace the terminal cover you must tighten the cable gland first now. Failing to do this now may
rotate the cable inside the connection box, which can lead to loose contacts, malfunctions and sparks. Hold
the inner washer with a spanner or pliers to prevent it from turning when fastening the cable gland. Make
sure that the cable gland is as tight as possible, providing strain relief for the cable, while the wires are not
twisted.
5. Only then replace the terminal cover and make sure you place the tooth lock washer at the same spot.

Installing the reflector and lamp
The coverage of your reflector depends on the light levels you want to achieve and the output of your lamp. With a
600W 1000- 1100 μmol s-1 lamp you can cover an area of almost 1 square meter (~11 square feet) with 900-1000
μmol s-1 m-2 average. The reflector has a rectangular (wide) throw.
Keep your reflector away from combustible materials at all sides. Use reliable mounting materials and keep
your lamp cords away from the direct heat from the lamp and the reflectors. Make sure that the lamp cord does
not touch any hot parts of the reflector. Make sure the lamp is clean and inserted correctly. Use light hangers
or small chains to hang the reflectors at the correct height.
The recommended distance to a crop:
400W lamp – 40 cm
600W lamp – 60 cm
750W lamp – 75 cm
Only relamp with lamps that are suitable for an open reflector. When using MH lamps, use self shielding lamps.
Let the reflector and lamp cool down and disconnect the ballast from mains when replacing a lamp. Use
gloves to keep the lamp clean, as the lamp surface becomes very hot. Screw in the lamp firm, but not to tight to
prevent breaking the lamp. Always check the center contact for damage when replacing a lamp.
Lamp replacement
Always install the lamp before connecting your ballast to mains.
Always be sure to connect your lamp cord to the ballast before switching it on
When changing the lamp always disconnect the ballast from mains by removing the mains plug. Let the
lamp and reflector cool down for 20 minutes before changing as they can be very hot. When replacing a
defect lamp without disconnecting mains from an electronic ballast the new lamp may not start:
disconnecting the power will in many cases reset the electronic ballast safety circuitry.
Only use lamps in this fixture that have been rated safe for open fixture use.

Reflector replacement
The HortiStar HR96 reflector is a precision high efficiency reflector that
should be handled with care. If it is damaged or deformed you should
replace it. We recommend to change the reflector every year for optimal
results. Replacement reflectors are available from your Gavita reseller.
To replace the reflector you do not have to remove the lamp, but it is
recommended to do so for easy installation. Pull up the lever at the end
of the reflector bracket while holding the aluminum reflector at that end.
The reflector will unlatch and can be removed now by pulling it over the
lamp / unlatching it. When inserting the new reflector make sure the
notches are in the appropriate holes. Always let your lamp and reflector cool down first before changing the
reflector to prevent injuries.
Using the lever to unlatch the reflector, aligning the notches with the reflector holes
Maintenance
Keep the bracket clean from dust and dirt with a dry or damp cloth. When using a damp cloth please disconnect
the power first. We recommend you check your electrical connections regularly: check if the plugs are inserted
completely and don’t show any (contact) damage, check if the wiring is undamaged and that the wire ends
connected to the reflector are tightly secured in their terminals. For stranded wire always use cable end sleeves.
The Miro aluminum reflector should not be cleaned with any detergent or water, use a soft dry soft cloth to avoid
scratching the material. Do not touch the reflective material. Replace the Miro reflector each year together with
your lamp. Do not use sulfur vaporizers when lamps are operating and do not use sulfur vaporizers or water
misters close to your reflectors. Sulfur and calcium deposit will damage your reflector and decrease the
efficiency of your reflector.
You can not clean the reflector without damaging it. Wiping it carefully with a soft cloth is the best you can do.
Never use polishes, detergents, sprays or normal tap water when wiping your reflector. If you need a damp cloth,
use a completely clean soft cloth with demi water only, or pure alcohol.
We recommend to change your reflector once a year, together with the lamp.
