Ecoxotic LEDs burning out?

[TXSea]

Okay Okay, I am not hear to bash these LEDs. I am just curious to see how many others have had these start to burn out on them. Both of my Pro modules are starting to ooze a brown jellyish substance from the LEDs themselves. Ecoxotic has been supportive in having them replaced but maybe I should just go topless with my tank and mount a fixture above it for the sake of my LEDs? I have SilenX fans on the hood but I don't think it is helping much. Any takers on this? 350gt I know you own these. Give me you 2 cents please!

none of mine have anything oozing out.

I had one of mine burn out on me but it was my fault and ecoxotic took care of it.

could it be the glue surrounding the leds? Mine were getting hot in the hood, so I chopped it all up. I actually like the older models as they are actual LED bulbs, not those chips or w/e they are...

You mean you took the hood off? I noticed that they make a fixture piece that allows you to mount them to the back of your tank have the hang over instead of in the hood. I don't know if its glue or not but it is coming out of the center of the LEDs. I am seriously thinking of going hoodless with it and figuring out some way to keep my fish from jumping out of the tank.

ya I chopped up the inside reflector that the lights were attached to, not the hood itself.. that and the plastic lens cover I left alone.

High output LEDs really need large heat sinks, and good ventilation. Almost all LED failures (other than some manufacturing failures Philips had a couple of years ago) are from poor heat sinking/ventilation. Contrary to popular belief, they DO heat up. In a marine environment where humidity approaches 100%, it's hard to cool them.

They do get hot, but not too hot. I was running three with no fans inside a little aquapod hood. I had a heat issue as I moved them closer together, before that they were spaced a inch in between and they worked fine for months. They just needed a little spacing to breathe, and make sure the heat sinks have space Inbetween them and the hood, I added some rubber spacers to give me that space..

I agree..I think between two you have to keep at least of 2 to 3 inches space so that these LED will not heat more. And beside rubber spacers it is also possible to add small 2 inches wooden spacers. These will be a also resist to get LED hot.
