Review on Chanzon 25Pcs 1W 3W 5W LED Heat Sink (2 Pin Black) Aluminum Base Plate Panel PCB Circuit Board Substrate 20Mm Star DIY Heat Sink Cooling For COB High Power LED Chips Lamp Beads 1/3/5 Watt by Keith Baker
Works Great! Easy to Use.
The 1W 6000k diodes probably don't require this level of heat management if operated in the open air, but they do warm these heat sinks up. These provide great heat dissipation, easy to read polarity markings. large solder tabs for power inputs and jumpers and a professional look. Worth the price. The downside is that there are too many in the package and now I need mare diodes!
- Perfectly fit for 3w & 5w
- One faulty heat sink could damage the entire LED circuit, resulting in additional costs and time to fix
