70W Samsung LM561C S6 LED Grow Light Module (1170x20mm) – High Efficiency 3000K Aluminum PCB for Horticulture
Unlock the full potential of your indoor garden with our premium 70W LED Grow Light Engine. Engineered for professional cultivators and DIY enthusiasts, this module combines the industry-leading efficiency of Samsung LM561C S6 chips with a robust Aluminum Base PCB design.
Whether you are building a custom quantum board or upgrading a commercial greenhouse, this 1170mm long strip offers the perfect balance of light intensity, spectrum quality, and thermal management to maximize your yield per watt.
Key Selling Points
1. Extreme Efficiency with Samsung S6 Chips
Powered by Samsung LM561C S6 diodes, this module meets the "gold standard" of the plant lighting market. The S6 bin ensures higher Photon Flux Efficiency (PPE), generating 15-20% more usable light for your plants compared to traditional LEDs at the same 70W power consumption.
2. Spectrum Optimized for Flowering
The 3000K warm white spectrum is rich in the 600-700nm red wavelength. This is the most active region for photosynthesis, specifically aiding in stem thickening, flower bud differentiation, and fruit swelling. The CRI>80 also allows you to clearly observe leaf color to diagnose nutrient deficiencies or pests early.
3. Industrial-Grade Thermal Management
Heat is the enemy of LEDs. We utilize a 2.0 W/m.k high thermal conductivity aluminum substrate paired with 1oz thick copper foil. This ensures rapid heat transfer from the chips to the heatsink. Even during long operating hours, the low junction temperature guarantees stable light output and extends the lifespan to over 50,000 hours.
4. Flexible OEM Customization
We support deep customization. Beyond standard electrical parameters, we can print your brand Logo directly on the PCB. For lighting assemblers and brands, this is the best way to build brand recognition and increase product value.
Applications
DIY Quantum Boards: Perfectly suited for custom quantum board projects.
Vertical Farming: Ideal light source for multi-layer growing racks.
Greenhouse Supplemental Lighting: Acts as a supplement to natural light, especially on cloudy days or in winter.
Home Grow Tents: Suitable for vegetation or flowering supplementation in 2x2ft or 2x4ft spaces.
Frequently Asked Questions (FAQ)
Q1: Which growth stage is this 70W LED module suitable for?
A: The 3000K spectrum is excellent for full-cycle growth but performs exceptionally well during the Flowering Stage. The rich red spectrum effectively promotes bud formation and fruit development. If used during the seedling stage, we recommend raising the light height or pairing it with blue light to prevent leggy growth.
Q2: Can I plug this module directly into a wall outlet?
A: No. This is a DC module and requires a constant current LED driver. Based on the specs (48V/1460mA), we recommend using a Mean Well XLG-75-H-AB or a similar 48V constant current driver.
Q3: What does "2.0 W/m.k" thermal conductivity mean?
A: It indicates excellent thermal performance of the aluminum PCB. Standard boards often have only 1.0-1.5 W/m.k. Higher conductivity means heat dissipates faster, keeping chip temperatures lower, ensuring more stable light output and a longer lifespan.
Q4: Can I customize the Logo on the PCB? Is there an MOQ?
A: Yes, we offer OEM services and can silk-screen your logo on the PCB. Small batch customization is usually supported; please contact our sales team for the latest MOQ and quote.
Q5: Do the Double Pin Molex connectors support daisy-chaining?
A: Yes, the connectors are designed as 2-in/2-out (2+, 2-), supporting simple parallel or series connections (ensure total voltage/current is within driver limits), allowing you to link multiple modules to cover larger growing areas.
