Must use with the 3W LED Cips

My original grow light was constructed without these mounting plates and the LEDs failed after about 100 - 150 hours. Without the plates the chips will start to draw excessive current and eventually burn up. I mounted 4 plates to a sheet of aluminum using ArcticAluminum thermal epoxy then installed the LEDs. It was a simple matter to wire the plates together with buss wire. I stuck some captan insulating tape under the wires just in case. With the LEDs on the plate the temp is around 28C just warm to the touch.

Pros

Perfect match for my LED light

Cons

The 1W, 3W, and 5W LED heat sinks may not be suitable for some use cases, requiring the purchase of additional products
