Issues with MARS 3ft LED

[BRIGGZY]

Hello all!
I recently bought a tank and all was well, however yesterday half of the light on the left hand side was not as bright, almost off (blue light all work as normal both sides) I then noticed the far left fan was off. I’m assuming the lights does not go full strength if a fan has stopped? Or maybe there is a power issue?
Any advice would be appreciated

I'm not sure how to help but I am going to follow along because I have the smaller version of these lights.
I don't like the fans that come with Mars Aqua so I change them out with a more reputable brand.
I am not sure if they make it for the larger light, but SB reef lights makes LED light boards that fit in the Mars Aqua. In my opinion they have a better color spectrum.

It looks like it's missing a heat sink or they jut come without one??

They don't have one. They rely on the fans to keep the board cool. The SB reef lights board is thicker and is supposed to help with cooling, but I am not sure it makes any difference.

It sounds like one of the LED drivers went bad - I would test their VDC output with a multimeter.

You probably do not want to hear this, but these are built & made to toss and replace. I am sure that you can probably fix it, but the cost might be more than a new one... and who knows how long it will last once you do since other stuff will have gotten hot also.

So I have resigned to the fact that the left side is probly stuffed, spoke to an electrician today and he said the leds on the left might be damaged with the fan not running, and buy the time I go to the effort of replacing, I could just buy a new one. Will use till it dies. Might buy some hang on back lights, has anyone used them? start with one, then add more once the current light dies

Also, do you have to hang the lights??
