Gavita Pro 6 750e DE

Gavita Pro 6/750e DE FLEX

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 were the first to launch a double ended 1000W HPS lamp in this market, and we were also the first to introduce a double ended 750W HPS lamp. This lamp bridges the gap between a 600W single ended, and a 1000W double ended fixture. more/less

In many rooms you just don’t have the height to run a 1000W fixture at 100%, and in other rooms you don’t need the intensity. Running a 1000W lamp at 750W all the time is a not a desirable situation as the lamp does not come to its full efficiency and the spectrum deteriorates. In those situations the 6/750 DE FLEX is the ideal solution, more efficient, cheaper and with a much better spectrum. We call it the 6//750 as the efficiency of the lamp, dimmed to 600W, is still really good: as good as any other 600W industry standard HPS lamp.
With the 750W lamp you can come almost a ft closer to your crop (a bit less in overlapping plans).

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 400, 500, 600, 750 W, and 825 W  boosted output. The Master Controller can centrally control the output hundreds of fixtures in a range between 375 and 825 W 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 high frequency ballast was specifically designed for the Gavita double ended HPS lamp, resulting in an accurate, optimal output, a stable burning lamp and a better light maintenance over time. The ballast is not suitable to run Metal Halide lamps. 
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 6//750 with the HR96 DE reflector is about 3x4.5 ft (90x135 cm) at 2.5 ft distance in overlapping plans, providing light levels of up to 1000 µmol s-1 m-2. 
The fixture’s light source is a Gavita Pro 750W double ended HPS lamp, generating 1450 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.

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 between 600 and 1150W, adjusting your light to changing circumstances or grow 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.

Gavita Pro 750W 400V info

Gavita Pro Plus 1000W EL DE 330px 237px min min

Typical applications for 750W lamps are vegetative rooms, combinations with plasma lighting, smaller rooms with lower intensity and rooms with a limited distance to the crop. 
Gavita was the first to introduce a 750W double ended lamp and fixture for horticulture, increasing the efficiency of single ended 750W fixtures by about 20-30%. They are now the standard in horticultural lighting for 750W systems. 
Gavita pioneered the use of double ended lamps in this industry. These professional lamps offer you the highest output and light maintenance in the market today. Backed by decades of horticultural experience, Gavita recommends these lamps for use in her professional fixtures in horticulture. 
Our DE lamps output 15-35% more PAR light than traditional single ended lamps and have a much better light maintenance, which means that you only have to change your lamps once a year. 
The double ended construction enables the arc tube to be in stable the center of your reflector, for optimal optical placement. No more sagging heavy lamps in your reflector that destroy the throw of your fixture.  The absence of a frame wire further increases the output and uniformity. 
The  narrow lamp reduces interference with reflected light from the reflector. It is nitrogen filled instead of vacuum, allowing the arc tube to be smaller while maintaining the correct arc tube temperature. You should not use our double ended lamps in direct air cooled fixtures, as they cool under the optimal temperature, reducing the output considerable. 
The smaller arc tube results in a higher light density than single ended lamps, improving the penetration of your crop.
Higher light output results in lower infra-red output, as energy in a lamp is converted to light and heat: The more light, the less heat is generated.
