Brown spots on my spider farmer light

I've read a lot about brown spots on the spider farmer lights, it's more than likely the adhesive they use but I am worried it's a fire hazard.
I reached out to spider farmer but no response yet. I've got seeds about to pop I'm kind of was looking for reassurance that the light is safe.
I've heard a few stories about fires started with people's spider farmer lights and I'm not sure if there's any truth to that, some people don't take care of there stuff or maybe there was a visual defect to cause these fires, some people just love to hate on spider farmer.
I can post pictures if needed, there is no bubbling just some brown marks around some diodes.
I would appreciate any advice.

If its the spots im thinking about, those brown marks are caused by a nutrient, I forget which one. This is why some companies coat their boards with silicone.
