20W-1ft led tube board
r2t
Overview
The 20W Linear LED Module PCBA is a high-efficacy, heavy-duty light engine engineered for high-performance commercial and linear architectural luminaires. Measuring 300mm × 20mm × 2mm, this rigid aluminum board incorporates 60 pieces of premium Samsung 561C LEDs arranged in a 10-series / 6-parallel (10S6P) circuit layout. Operating on a 26–36V DC constant current (300mA) supply, it features a heavy 2oz copper foil and 2.0 W/m·K thermal dielectric layer for optimal heat dissipation and ultra-low thermal resistance. Equipped with 4 single-pin push-in connectors, it ensures solderless, rapid wire interconnection for OEM/ODM fixture manufacturers.

Full CCT Spectrum Available: Available in warm to cool color temperatures (2700K, 3000K, 3500K, 4000K, 5000K, 6500K) with CRI 80+ for versatile commercial lighting applications.
applications & Fixture Compatibility
Commercial Architectural Lighting: Linear pendant lights, recessed office troffers, and perimeter cove lighting.
Industrial & Retail Illumination: Supermarket trunking systems, shelf lighting, and LED batten fittings.
Custom OEM/ODM Luminaire Design: Ideal drop-in replacement engine for luminaire manufacturers designing low-profile linear fixtures.
Q&A:
Q1: What LED driver specifications are required for this 30W linear PCBA board?
A: This module requires a constant current LED driver delivering 300mA with an output voltage window covering DC 26V to 36V (approx. 30W output per board).
Q2: How do the 4 single-pin connectors work on this 300×20mm module?
A: The board includes 4 surface-mounted single-pin push-in terminals (typically 2 for positive/negative input and 2 for pass-through daisy-chaining). They accept solid or tinned stranded wires without manual soldering, significantly reducing labor time during luminaire assembly.
Q3: Can this 300x20mm PCB layout be customized for different dimensions or LED brands?
A: Yes. As a custom LED PCB & PCBA manufacturer, we can adjust the aluminum board dimensions, change connector locations, modify circuit series/parallel ratios, or substitute LEDs with other brands (e.g., Cree, Lumileds, Bridgelux, Sanan) based on your OEM requirements.
