The Gavita Pro 600/750e DE is part of the Gavita Pro line e-series, their next generation professional grow light solutions. Gavita were the first to launch a double ended 1000W HPS lamp in this market, and 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.
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 installations and adds safety features such as automatic dimming of your lights at high temperatures and even a safety shutdown.
Features and 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 Gavita’s fixtures are FCC compliant.
Horticultural Design
Their fixture is not a contraption of a remote ballast and reflector: it is designed as a complete fixture. The high quality white coating is durable and UV resistant. All the terminals are sealed with gaskets and contact. Terminals are also of high quality.
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
The 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. Gavita 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 400 and 825W, 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
These 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. Gavita’s ballasts are designed to power their horticultural double ended lamps at exactly the right high frequency and power for optimal and stable output, and a long light maintenance. Their ballasts are only suitable for high frequency HPS lamps as specified in the product manual.
Soft Start
Unlike magnetic ballasts their 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
The 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
Gavita ballasts are completely sealed and passively cooled through the extrusion aluminum ballast housing. Their 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 moisture. Therefore their 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
The 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
Their e-series ballasts can be remote controlled by the 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 your 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.

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. They 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 foot 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, 750W and 825W boosted output. The Master Controller can centrally control the output hundreds of fixtures in a range between 375 and 825W output power. Using the Master controller safeguards your valuable crop by the added auto-dim and auto-shutdown features which 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 spread is about 90 x 135cm at 75cm 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.
