Gavita Pro 1000W 400V DE e-series

The ‘e’ in ‘e-series’ stands for external control. These fixtures can be controlled centrally by a Gavita Master controller. This replaces the often cumbersome installation with contactors and clocks, and adds safety features such as automatic dimming of your lights at high temperatures and even a safety shutdown.We improved the electronics and changed the way the ballast is built, by mounting the PCB and warm components directly on the heat sinks instead of in a ballast bracket. The much cooler electronics result in a greater reliability and a longer life. The new design of the housing even increases that effect.

Features & Benefits:

Complete fixture
The integration of ballast and reflector results in a compact fixture. No external lamp wires results in low EMI, which makes it easier to comply with FCC regulations. All our fixtures are FCC compliant.

Horticultural design
Our fixture is not a contraption of a remote ballast and reflector: it is a fixture designed as a complete fixture. The high quality white coating is durable and UV resistant. All the terminals are sealed with gaskets and contact and terminals are high quality.

Balanced fixture
The fixture is balanced, so it can be mounted by just two hanging points. This enables much easier installation by brackets from C-profiles for example.

400V lamp technology for high frequency electronic ballast
The high voltage lamp technology results in a better efficiency of the arc tube: more light for the same power (10-25% more than traditional single ended lamps)! These lamps are best suited for extreme high frequency electronic ballasts, creating a stable arc without acoustic resonance, assuring optimal output and a long lamp life. The smaller arc tube and outer balloon require the lamp to be nitrogen filled instead of vacuum, which prohibits it to be air cooled. Air cooling of the lamp results in lower lamp temperature, which results in sub-optimal light output, up to 15% less than specified. Therefore these lamps are not suitable for direct air cooled fixtures.

Replaceable reflector
Our bracket is designed to be able to change you reflector quickly. Miro aluminum can not easily be cleaned, and when you clean it, it will never be as good as a new reflector. We recommend to change reflectors every year in a “dirty” environment (dust, foggers, sprays) or every two years in a clean environment.

Controllable output
With the output dial, you can select an output power, adjusting your light to changing circumstances or growth phases. Do remember though that every new lamp needs to burn in at 100% for at least 100 hours to stabilize before you dim or boost it. Failing to do so can lead to start-up problems when lower output power is selected and decreased output.

Double ended lamp
Our Double ended HPS lamps are the most efficient HPS lamps available. Double ended lamps have the advantage that they are always in the focal point of the reflector, there is no frame wire in the lamp which results in less light interception, and the lamp is very small in diameter which prevents reflected light to be intercepted by the lamp in the reflector.

High frequency electronic ballast
There is no such thing as a universal ballast. You will get the optimal output when you match a lamp and ballast which are designed for each other. Our ballasts are designed to power our horticultural double ended lamps at exactly the right high frequency and power for optimal and stable output, and a long light maintenance. Our ballasts are only suitable for high frequency HPS lamps as specified in the product manual.

Soft start
Unlike magnetic ballasts our electronic ballasts never use more power than their specified power during the start-up sequence. Lamps reach their full power much quicker though than with a magnetic ballast.

No in-rush current
Our e-series fixtures are constantly connected to your mains supply, just like a television that is on stand-by. Because of that it never creates a high inrush power when switching on. You can fire-up all your lamps safely.

No moving parts, optimal thermal management
Our ballasts are completely sealed and passively cooled through the extrusion aluminum ballast housing. Our housings provide optimized thermal management, which keeps the electronics much cooler than in die-cast housings. Good thermal management is extremely important for the lifetime and reliability of the electronics.

Sealed housing with Gore-tex ventilation plug
Electronics are very sensitive to moist. Therefore our ballasts are completely sealed and equipped with a ventilation plug. When the ballast is switched on and heats up, the air inside the ballast expands and is vented out through the ventilation plug to protect the seals. When the ballast is switched off and the air inside the ballast cools down, the Gore-tex ventilation plug only lets in the air, and keeps out the dust and moisture, safeguarding your sensitive electronics.

Status LED
The Status LED provides information about the operating status of the ballast. It senses connection with the controller, indicates a starting lamp, end of life, over temperature, too high input voltage, too low input voltage and it even has a memory for alarms.

Miro aluminum reflector
Our HR96 reflector is made of a very high grade Miro aluminum which provides optimal reflectance of light to your crop. This is the reflector of choice for horticultural growers world-wide, to provide uniform light in an overlapping plan with great plant penetration from all sides. The reflector is a medium wide reflector, providing optimal horizontal penetration of the crop. Remember: the sun is never straight above plants, they do need light at an angle for optimal penetration.

Soft dim
When adjusting the output of your fixture the output power will very gradually change, protecting your lamp. It can take a minute per step, making this process so gradual that your eyes can hardly see it. Rest assured, they will dim.

Suitable for Gavita Master Controllers
Our e-series ballasts can be remote controlled by our Gavita Master Controllers. They replace your timers and contactors, and put you in full control of your ballasts. You can centrally adjust the output of your ballasts, even with sunrise and sunset settings. Moreover they protect your crop by two temperature safety features: When you climate control is not able to maintain the optimal temperature your master controller will automatically dim your lights. In case of a climate control failure they will switch off your lights, protecting your valuable crop and preventing overheating problems.

Plug & Play installation
Connect your fixtures to the master controller with the standard controller cables provided with the controller and the fixture. It’s all plug and play: you do not need a screwdriver. Gavita provides original accessories if you require replacements or different length controller cables.

FCC compliant
All our fixtures are FCC approved. No fake Chinese certificates: our FCC certificates are from a US lab and all our boxes include an official declaration of conformity with report number. Our retail fixtures are FCC class B compliant, our industrial fixtures minimal FCC class A. We check our production by sampling, and measure the EMI in our own test room for continuing compliance. FCC approval however does not mean that there is no EMI: it just confirms that they are within the legal limits.

More information

The fixture comprises of a ballast, reflector and lamp in one complete compact package. Made according to horticultural standards, the housing of the ballast is sealed and contains a gore-tex® plug to ventilate the housing, while keeping dust and humidity out.
Ballast output is either controlled by the Gavita Master controllers, or an external switch, allowing it to be adjusted to 600, 750, 825, 1000 W, and 1150W boosted output. The Master Controller can centrally control the output hundreds of fixtures in a range between 500 and 1150W output power. Using the Master controller safeguards your valuable crop by the added auto-dim and auto-shutdown features, and completely automates your light control.

The compact complete fixture contains a lamp, HR96 reflector and horticultural quality ballast in one comprehensive package. The higher output and added efficiency of the industry standard HR96 reflector make this the workhorse of the family.
The reflector is replaceable (we recommend to do this every year to two years) and there is a choice of replacement reflectors:

• The HR96 DE for overlapping configurations, assuring optimal uniformity and penetration. This is the industry standard reflector delivered with the fixture.
• The W 150 DE for wide configurations, where uniformity and lower light levels are required in large rooms. 150 degrees beam angle, for double ended lamps.
• The M 110 DE SR for applications in single rows and small rooms, where a single reflector needs to create uniformity and high light levels. 110 degrees beam angle, for double ended lamps.

The spread of the Pro 1000 equipped with the HR96 DE reflector is about 4×6 ft (110x180cm) at 3 ft distance in overlapping plans, providing light levels of up to 1000 µmol s-1 m-2. The reflector is replaceable (we recommend to do this every year to two years).
The fixture’s light source is a Gavita Pro Plus 1000W double ended HPS lamp, generating 2100 µmol s-1 of light. With a light maintenance of over 96% per 5000 hours you only need to replace it once a year.

Mounting is easy because the fixture is balanced and only requires two hanging points. For c-profile installations we have convenient brackets available.
