Key Features of Our LED Module

Designed for efficiency and longevity, this specific board configuration demonstrates our manufacturing capabilities:

• Top-Tier Components: Populated with 288 pieces of Samsung LM301H (available in various CCTs from 2700K to 6500K) and 8 pieces of Cree XPE 660nm for deep red spectrum enhancement.

• Superior Thermal Management: Built on a 2.0mm Aluminum base with 2.0 W/m.k thermal conductivity. This ensures heat is transferred away from the diodes quickly, maintaining lumen output and extending lifespan.

• Optimized Circuitry: Configured as 16 parallel strings with 18 LEDs in series, operating at a constant current of 2600mA (Voltage range: 46.8~58V).

• Plug-and-Play Connectivity: Pre-installed with 4x Molex single pin connectors, simplifying the assembly process for fixture manufacturers.

• Precise Dimensions: 173.6 x 285.8 x 2mm, Net Weight: 290g.

Our Customization Services (OEM/ODM)

While the specifications above represent a high-standard configuration, R2T Industry excels in customization. We can modify:

• Board Shape & Size: To fit your unique fixture housing.

• LED Layout: Adjusting the mix of white and red diodes.

• Surface Finish: Offering HASL, ENIG, or OSP depending on your soldering requirements.

• Full PCBA Assembly: We can source drivers, connectors, and perform the full assembly, delivering a ready-to-install module.

Frequently Asked Questions (FAQ)

Q1: What is the advantage of using Samsung LM301H diodes on this PCB?
A: The Samsung LM301H is currently one of the most efficient white LEDs on the market. It offers a higher photon efficacy (umol/J) compared to older generations, meaning your grow light produces more usable light for plants while consuming less electricity.

Q2: Can you customize the Color Temperature (CCT)?
A: Yes. As a custom PCB manufacturer, we can populate the board with the specific CCT bins you require, ranging from warm white (2700K/3000K) for flowering stages to cool white (5000K/6500K) for vegetative growth.

Q3: What is the significance of "2.0 W/m.k" thermal conductivity?
A: Thermal conductivity measures how fast heat moves through the material. A rating of 2.0 W/m.k is considered high performance for standard aluminum PCBs. It prevents "hot spots" on the board, ensuring the LEDs operate at lower temperatures, which significantly reduces light depreciation over time.

Q4: Do you provide just the bare board or the assembled PCBA?
A: R2T Industry provides both. We can manufacture the bare Aluminum PCB, or we can provide a full turnkey PCBA service where we source the LEDs and components, perform SMT placement, and test the final board before shipping.

Q5: What is the MOQ for custom LED PCB orders?
A: We support both prototyping and mass production. Please contact our sales team with your Gerber files or requirements for a specific quote based on volume.
