Hi Guys. Any ideas on what is the problem with Satura Led Spot Pro v2 Standard fixture that is constantly fading out & in during operation? Is it the module problem or power supply? Do I need to replace parts for this issue? Any inputs and advise are highly appreciated. Thank you

Greetings, this can happen due to overheating, check the fans @the led engine and insure they are rotating properly and to speed.
curious if you sorted this issue out. I had same issue for 4 of them over time doing this. figured it out though.
@Event Lighting Dir How did you figure it out? I'm having this problem with one of our fixtures
It’s likely a power supply or driver issue. Check connections; if secure, replacing the power supply may fix it.
@True Foley There is a THERMISTOR attached directly to the LED chip located within the cooling fins.
The temperature of the chip changes the resistance of this thermistor resulting in a temperature reading for the fixture.
When this thermistor starts to fail, it fails in the direction of "overheating" which causes the fixture to fade off for safety. this thermistor is not easily replaced in my circumstances. its tiny and very close to other critical and delicate components of the LED chip.
I traced this sensor wire back to the PCB, and bridged the connector with a little resistor I found to work with basic trial and error technique. watching the temperature reading displayed on the fixtures display.
This essentially resulted in a totally fixed/static temperature reading that was equal to a "medium" fan speed.
My fixtures do NOT get hot as they are in a well air conditioned environment, despite operating at full for 8-10hrs every day.
worked for me, been almost two years since. definitely not a "standard" repair but the choice was basically already made due to the fact that a replacement LED Module is something like 3grand to replace.
