The Mars Hydro FC4000 320W is a high-performance full-spectrum LED light designed primarily for rectangular grow boxes and growing areas measuring approximately 120 × 60 cm. It combines Bridgelux 3030 LEDs with additional OSRAM Deep Red 660 nm LEDs, providing a broad spectrum suitable for both plant growth and flowering.
The light draws 320 W and achieves an efficiency of up to 2.85 µmol/J. Its strip-style design helps distribute light evenly across the entire growing area and minimizes the formation of a strong central hot spot. The FC4000 also features power adjustment, passive cooling, and the option to upgrade to Mars Hydro’s smart control system.
The Mars Hydro FC4000 uses Bridgelux 3030 LEDs for the primary spectrum and additional high-efficiency OSRAM Deep Red LEDs that emit deep red light in the range of approximately 660 nm.
The declared efficiency of the entire lamp is up to 2.85 µmol/J, while the OSRAM red LEDs used can achieve an efficiency of up to 6.24 µmol/J.
The combination of white light and deep red provides a spectrum designed to support plants throughout their entire growth cycle.
The Mars Hydro FC4000 utilizes a full spectrum covering the ranges of 2800–3000 K, 4800–5000 K, and 650–665 nm. This allows a single lamp to be used from the seedling and vegetative stages all the way through flowering and fruiting.
The FC4000 is designed for a growing area of approximately 120 × 60 cm. Its elongated design, measuring approximately 113 × 36.1 cm, fits well with the proportions of rectangular grow tents.
With a power output of 320 W, the lamp can serve as the primary light source during both the vegetative stage and the flowering stage, which requires higher light intensity.
Instead of concentrating a large number of LEDs in a small area, the Mars Hydro FC4000 uses several elongated LED strips. This allows the light sources to be distributed over a larger portion of the grow area.
This design helps achieve more even lighting and minimizes the difference between the center of the grow area and its edges. This is particularly useful in rectangular 120 × 60 cm grow boxes.
The built-in power control allows you to adjust the light intensity to the current stage of plant development. There is no need to use the full 320 W from the start of the cycle.
You can use a lower intensity for young plants and then gradually increase the power as their light requirements grow. This also helps reduce energy consumption when maximum power isn’t needed.
The lamp’s aluminum construction also serves as a heat sink. The large surface area of the fins and the space between them help effectively dissipate heat.
The FC4000 does not use fans for cooling, so it operates quietly and has no additional moving parts that require maintenance.
The light can be upgraded with smart control. When used with a compatible controller, you can access additional features such as scheduling operating times or remotely adjusting light intensity.
Depending on the configuration, the system is compatible with the following solutions:
Compatible controllers and additional sensors are available separately.
The Mars Hydro FC4000 also allows you to connect compatible lights using a control cable. This solution makes it easier to control a larger number of fixtures in complex setups.
When connecting devices from different series or model years, check the compatibility of the connectors and control system beforehand.
