Elevate your horticultural lighting setup with our premium LED Grow Light PCBA, engineered for professional cultivators and DIY enthusiasts. This high-density quantum board features a powerful combination of 252 Samsung LM301H diodes and 12 Osram GH CSSPM3.24 (Deep Red) emitters, delivering a scientifically optimized full spectrum for maximum photosynthetic activity.
Built on a robust 385x200mm aluminum substrate with a HASL finish, this board ensures superior thermal management and longevity. Whether you are building a custom grow tent setup or upgrading an existing fixture, this board provides the photon efficacy your plants crave during both vegetative and flowering stages.
Key Features & Specifications
Premium Diode Configuration
White Light Engine: Equipped with 252pcs Samsung LM301H (3500K). The LM301H is the industry standard for high efficacy and reliability, providing a warm white spectrum essential for robust vegetative growth and structural integrity.
Far-Red Enhancement: Integrated with 12pcs Osram GH CSSPM3.24. These deep red diodes are strategically placed to trigger the Emerson Effect, significantly boosting photosynthesis rates and accelerating flowering/blooming cycles.
️ Superior Build Quality
Dimensions: 385mm x 200mm x 1.6mm.
PCB Material: High-quality Aluminum MCPCB (Metal Core Printed Circuit Board) for excellent heat dissipation, ensuring the LEDs operate at optimal temperatures to prevent lumen depreciation.
Surface Finish: HASL (Lead-Free). This finish ensures strong solder joints and protects the copper traces from oxidation, extending the lifespan of the board in humid grow environments.
Copper Weight: 1oz. Sufficient copper thickness to handle high current loads without voltage drop issues across the long strips.
⚡ Electrical & Connectivity
Input Voltage: Compatible with 40-48V DC constant current drivers.
Max Current: Designed to handle up to 3000mA (Please ensure adequate cooling/active fans when running at high amperage).
Connectors: Features 2pcs Molex double-pin connectors for secure, daisy-chain capability or direct driver connection, ensuring a stable power supply without loose wiring.
Why Choose This Board? (The Science of Growth)
This board isn't just about brightness; it's about spectral precision. By combining the broad spectrum of the Samsung 3500K with the targeted peak of the Osram Deep Red, we create a light recipe that mimics the most effective parts of sunlight.
High PPF Output: The density of 264 total diodes on a compact footprint delivers intense light penetration, reaching lower canopy levels.
Energy Efficiency: The LM301H binning ensures you get more light (photosynthetically active radiation) per watt of electricity consumed compared to older LED technologies.
Versatility: Perfect for seedlings, veg, and bloom stages due to the balanced color temperature and red spike.

⚠️ Important Installation Notes
Heatsink Required: This is a bare PCBA. It must be mounted to an aluminum heatsink with thermal glue/tape to prevent overheating.
Driver Matching: Ensure your LED driver matches the voltage (40-48V) and does not exceed the 3000mA max current rating.
Handling: Avoid touching the LED lenses directly with bare fingers to prevent oil residue from affecting light output.
Q1: What kind of LED driver do I need for this board?
A: You need a constant current LED driver that supports an output voltage range covering 40-48V and a current output of up to 3000mA (or adjustable up to 3A). Popular compatible brands include Mean Well (HLG series), Inventronics, or SOSEN. Note: Always check the driver's voltage/amperage curve to ensure it matches the board's requirements.
Q2: Do I need a heatsink for this PCBA?
A: Yes, absolutely. While the aluminum PCB helps spread heat, it cannot dissipate it alone. You must mount this board onto a passive aluminum extrusion heatsink or an active cooling system to prevent the LEDs from overheating and failing. We recommend a heatsink that matches or exceeds the board's dimensions (385x200mm).
Q3: Can I dim this board?
A: Yes, but the dimming function depends on your LED driver, not the board itself. Most modern horticulture drivers (like Mean Well HLG) come with a 3-in-1 dimming wire or support 0-10V/PWM dimming. The board will respond perfectly to the driver's output adjustments.
Q4: What is the benefit of the Osram Red diodes?
A: The Osram GH CSSPM3.24 emits light at roughly 660nm (Deep Red). This specific wavelength is scientifically proven to trigger the "Emerson Effect," boosting photosynthesis efficiency significantly when combined with white light. It is essential for promoting stretching during veg and dense bud production during flower.
Q5: How do I connect multiple boards?
A: The board features Molex connectors. You can daisy-chain boards if your driver has enough voltage headroom. For example, if you have a driver with a max voltage of 96V, you could theoretically run two of these boards in series. Please consult an electrician or lighting expert to calculate your specific series/parallel configuration safely.
Q6: Is this board waterproof?
A: The PCBA itself is not waterproof. It is designed for indoor use in controlled environments. If you require waterproofing for a greenhouse environment, you would need to apply a conformal coating or house the board in an IP65-rated fixture.
