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 John Bones

Revainrating 5 out of 5

Exactly what you need to mount Chanzon's LED chips.

Purchased these to go along with the Chanzon 10 pcs High Power Led Chip 4W RGBW 8 pins (300mA-350mA for Each Color 4 Watt) Multicolor Super Bright Intensity SMD COB Light Emitter Components Diode 4 W Bulb Lamp Beads DIY Lighting . Mounted the chips with a dab of thermal compound (I used Arctic Silver Céramique), and everything works as expected. They shipped in a single sheet still attached, so you can use part of the sheet as an array and keep them attached, or just bend them back and forth a couple times to snap one off and use singly. My only complaint, if you can call it that, is that these come in sets of 25 while the LEDs come in sets of 10, so unless you buy 5 x 10 LEDs and 2 x 25 Heat sinks you end up with extras. Would be nice if Chanzon matched up the quantities a little better, but for the price, you still can't beat it (and like me, you will probably end up coming back for more anyway, so hang on to those extras!)

Pros
  • These seem to be a quality base to mount to a metal surface for grow lights
Cons
  • The heat sink may cause interference with other electronic devices in the vicinity
