I see a lot of reports of failure here. I originally purchased one of these in 2015 to drive two LED strips for panel and flood lights in my RV-8. It worked flawlessly for several hundred flight hours (probably 10-20 hours actual lighting) and 5 elapsed years. I recently purchased a replacement after I physically damaged the original during a panel upgrade. The new one has added heat sinks on the transistors which should help. Here is my issue. The new replacement has slightly wider placement of the two POTs, requiring me to remake a panel overlay. I may return the product and make my own PWM which is a very simple circuit.

Right out of the box, one channel sputters and blinks in the lower 30% or so of its range. I swapped my red and white LED segments and confirmed that its the drivers and not the load causing this. Disappointed and wouldnt buy again.

Installed dual channel unit to control strip lighting. Worked great for 5 hours, then one channel lost its low end range. Doesnt come on until too bright to be useable at night.

one side quit in 10hr total failure in 300hrs

This unit was defective right out of the box. I hooked it up, and it will control 2 channels of LED strip lights. When I mounted it in the panel, the unit grounds out and both channels go out. Unusable.
