I just had my 4th Cree LED burn-out on my LED setup. The first few were because of corrosion from water. I have a rather tight canopy over my tank, and there is a lot of moisture. After this event, I replaced the bad LEDs and covered all of the contacts on the PCB star with silicone. This seems to have been better, since they lasted much longer this time. However, the LED closest to the water inlet has failed again due to corrosion.(I assume because it is near the most moving water, though I have my inlet pointing down with no splash). This problem may have also been accelerated because of the winter, since the water has a significantly higher temperature now than the air (condensation)
Does anyone have any recommendations for waterproofing? I also use a bit of LED strip lighting for moonlighting. I wasn't too concerned with the light output of this, so I simply sprayed it down with clear Thompson water sealant. I was thinking of doing the same thing, unless someone has a recommendation otherwise.
Edit: I just realized I should have posted this in DIY. I apologize
