Product Overview and Features
This image displays the KOSCHEAL K6400 640W LED Grow Light from a top-down perspective, showcasing its bar design. Below the light, a full spectrum graph, RJ45 ports, a dimmer knob, and hanging ropes with carabiners are visible, representing the light's features and accessories.
High-Efficiency Lighting
The K6400 utilizes LM301H EVO LEDs, each rated at 2.9 µmol/J PPE, delivering an industry-leading efficiency of 235 lumens per watt. With a real output power of 640W, it supports a maximum yield of 2.6g per watt.
Superior Heat Dissipation
Designed without fans, the K6400 operates silently. A large, solid aluminum heat sink is integrated into the fixture, ensuring efficient heat dissipation and contributing to the long lifespan of the LED bars. This design also helps reduce electricity consumption compared to traditional HID lights.
Full Spectrum for All Growth Stages
The K6400 provides a professional, customized full spectrum of light, optimized for all plant growth stages, from germination to flowering and fruiting.
A detailed view of the KOSCHEAL K6400 LED bars, highlighting the different types of LEDs: Red Light (660-665nm) for higher yields, Warm White Light (2800-3000K) to promote flowering and fruiting, and White Light (4800-5000K) for plant germination and growth. The image also indicates PPE of 2.9 µmol/J, PPF of 1856 µmol/s, and a coverage area of 4x4 feet (120x120cm).
This graph illustrates the professional customized full spectrum provided by the KOSCHEAL K6400 LED Grow Light. The X-axis represents wavelength in nanometers (380-780nm), and the Y-axis represents relative intensity, showing peaks in blue, green, yellow, orange, and red light, optimized for plant growth.
Foldable Design
The K6400 features a 180° foldable design, making it easy to transport, store, and install without complex assembly.
Setup and Installation
Follow these steps to safely set up your KOSCHEAL K6400 LED Grow Light:
- Unpack Components: Carefully remove all items from the packaging and verify against the package contents list.
- Assemble Hanging Kits: Attach the hanging kits to the designated points on the grow light fixture. Ensure they are securely fastened.
- Mount the Light: Use the lifting ropes and hanging kits to suspend the grow light from a sturdy support structure in your grow tent or cultivation area. Ensure the light is level and at the desired height above your plants.
- Connect Power: Plug the provided power cord into the grow light's power input port. Then, plug the other end into a grounded electrical outlet.
- Optional: Daisy Chain Connection: If connecting multiple K6400 units, use the RJ12 signal daisy-chain cable to link the lights. Connect one end of the RJ12 cable to the 'OUT' port of the first light and the other end to the 'IN' port of the next light. Repeat for additional lights.
- Optional: External Controller Connection: For external control, connect an RJ12 cable from your smart controller (not included) to the 'IN' port of the first grow light in the daisy chain.
Operating Instructions
Power On/Off
Once connected to power, the light will turn on. To turn off, disconnect the power cord or use an external timer/controller.
Dimming Control
The K6400 features an integrated dimmer knob for manual intensity adjustment from 0% to 100%. Rotate the knob clockwise to increase brightness and counter-clockwise to decrease it.

It shows the RJ cord ports for daisy-chaining and connecting to an external controller (not included), along with the integrated dimmer knob for manual intensity adjustment. The light supports 0-10V dimming and can control up to 50 lights in a daisy chain.
External Controller and Daisy Chain
The grow light includes a smart controller port (RJ12) for connecting to universal controllers (not included). This allows for advanced timing and dimming functions. Up to 50 K6400 units can be controlled simultaneously through a daisy-chain connection using RJ12 cables.
PPFD Map and Coverage
The KOSCHEAL K6400 is designed to provide uniform PPFD levels across a 5x5 ft coverage area. Refer to the PPFD map below for recommended light intensity at different heights and growth stages.
A PPFD (Photosynthetic Photon Flux Density) map for the KOSCHEAL K6400 640W LED Grow Light, tested in a 4x4 ft grow tent. The map shows PPFD values at different heights (12 inches, 18 inches, 24 inches) and indicates optimal PPFD ranges for seedling (100-300), vegetation (400-600), and flower (800-1000) stages.
- Seedling Stage: Maintain PPFD between 100-300 µmol/m²/s.
- Vegetative Stage: Maintain PPFD between 400-600 µmol/m²/s.
- Flowering Stage: Maintain PPFD between 800-1000 µmol/m²/s.
Adjust the hanging height of the fixture or use the dimmer knob to achieve the desired PPFD levels for your plants' specific growth requirements.
Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your grow light.
- Cleaning: Periodically wipe the LED bars and heat sink with a soft, dry cloth to remove dust and debris. Ensure the light is unplugged and cool before cleaning. Do not use liquid cleaners.
