### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Worked to stop the surge from led light.
  

*by R***2 on Reviewed in the United States on April 1, 2022*

While building a Bluetooth speaker/ work light/ phone charger. I was having trouble with the work light. Every time I turned it on the surge would trip the over current protection on the BMS. By installing this in line with the LED light it got rid of the surge and everything worked line.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Works perfect
  

*by A***R on Reviewed in the United States on November 23, 2021*

Used this to replace a fried one on my 3 LED light... Soldered in easy and fixed my light good as new... Many people throwing these nice lights out after the original one burns up..

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Work great but not what I expected
  

*by C***N on Reviewed in the United States on August 6, 2022*

These do work to slow incoming rush of current to my project.  Problem is that they can get extraordinary hot.  My project is a high efficiency project using batteries and these are not designed for maximum efficiency.  Not a problem with the product but with my assumptions.  They do work.
