LED Heatsink ZZHXSM 30PCS High Power 1W/3W/5W
The ZZHXSM heatsink is designed for high-power monochrome LED chips with multiple wattage options (1W, 3W, 5W). It features an anodized surface for durability and a 20mm star base for easy integration with common COB and LED modules. Thermal grease should be evenly applied at the contact surface to maximize heat transfer. This solution emphasizes simplicity, allowing straightforward welding and quick assembly in DIY cooling projects.
CHANZON 25pcs 1W/3W/5W LED Heat Sink (Black) 20mm Star
CHANZON’s black heat sink variants offer 20mm star bases and 2-pin compatibility for single-color LED chips. With a stated thermal conductivity of 1.6 and a straightforward welding process, these heatsinks support efficient heat dispersion for 1W, 3W, and 5W LED chips. They are suited for COB-based lighting or DIY COB modules where compact, reliable cooling is essential.
CHANZON 25pcs 1W/3W/5W LED Heat Sink (White) 20mm Star
The white variant mirrors the black CHANZON design with identical 20mm star bases and two-pin options. Its compatibility with 1W/3W/5W LEDs makes it a flexible choice for modular lighting projects, including stage lighting, accent lighting, and DIY COB assemblies. Proper attachment and thermal interface material usage are key for optimal heat transfer.
Easycargo Round Heatsink for LED
Easycargo offers a round aluminum heatsink designed for LED diodes and power electronics. Its dimensions, including an inside diameter of 6mm and an outside diameter of 20mm, align with common small-form-factor LEDs. This solution emphasizes compact cooling, making it suitable for tight spaces such as under-cabinet lighting or small COB modules where space is at a premium.
TX Aluminium Heatsink Cooling Fan+44mm Lens
TX’s heatsink with a cooling fan and a 44mm lens is designed for higher power LED applications, including projector-style lighting and floodlights. Copper core radiators enhance heat dissipation, while the 12V DC fan supports steady airflow for sustained brightness. Suitable for 20W–100W LED modules, this solution is geared toward DIY projects requiring robust cooling and focused lighting performance.
Buying Guide: Key Considerations for Choosing LED Heat Sinks
- Compatibility: Check base size and pin configuration. A 20mm star base is common for many COB and high-power LEDs, and two-pin designs cover standard single-color chips.
- Thermal Conductivity: Look for aluminum bases with good heat transfer properties and consider applying thermal grease at the contact surface to minimize thermal resistance.
- Power Handling: Choose a heatsink that matches the LED wattage you plan to run. Higher wattage LEDs benefit from larger, more efficient dissipation paths, or active cooling options like fans.
- Installation: Consider ease of assembly, welding, or soldering needs. Adhesive-backed options can simplify mounting, but ensure secure heat transfer nonetheless.
- Form Factor: Round versus square/rectangular shapes affect how you fit the heatsink into your enclosure and airflow path. Tight spaces may favor compact, round designs.
- Thermal Interface Material: Use an even layer of thermal grease or a thermal pad between the LED and heatsink for optimal conduction and longevity.
- Future Upgrades: If you anticipate higher brightness or different LED modules, select a modular heatsink with scalable cooling options or a compatible star base.
Additional Perspectives
For tight installations, white or black anodized heatsinks can blend with fixtures while delivering reliable cooling performance. If you expect sustained high output, fan-assisted solutions like the TX aluminium heatsink with a lens provide active cooling and focused illumination. When durability and DIY flexibility are priorities, standard 20mm star heatsinks from brands like CHANZON and ZZHXSM offer widely supported options for 1W, 3W, and 5W LED chips. Always verify the exact LED chip type and current requirements before finalizing a heatsink choice.
