kessil junk or bad luck

i dont have any kessil lights, but i was wondering if there getting warmer than they should? heat kills leds.

 

I have 4 of the a150 over my tank. I had problems with one being really blue after 6 months
so I emailed kessel & they called it "LED specteral shift" they sent me new one.
mine dont get to hot at all. but I'd imagine the 350s get twice as hot.
customer service is great. I really love the lights but crossing fingers that rest don't go bad after warranty is up.
Good luck

 

I'm by no means an electrician, but what do you have it plugged into? I've seen posts where reef controllers have been responsible for putting out too many volts. Is there anything else plugged into the same circuit pumps/powerheads/heaters that stray voltage could be causing some electrical interference? I would think after 3 times that it's something with your setup causing it, not necessarily the light itself.

 

Sorry that wasn't written very clearly... LED's in general are very susceptible to burning out if the proper voltage isn't delivered consistently....Yes, the light SHOULD have means to protect that type of thing from happening, but then again, the light SHOULD not just burn out for no reason either.

Having other items plugged into the same power source could be causing surges or fluctuations causing your kessil light to burn out...

It just seems very unlikely that after 4 attempts with the same model that you would just happen to receive malfunctioning units all 4 of the times. You would think the company would discontinue making the lights if they offer a 2yr warranty and they are consistently replacing them under warranty.

Anyways, hope you figure something out with it!

 

I've a Kessel 150w Ocean Blue over my biocube 29G since my HQI broke. So far so good but it's only been a month. My clam has responded well to the light as have the other corals in my tank but again it's only about a little over a month.

 

i have two A350w's on my 120 and i got them in june of 2012 and they are still runing strong...for me i use a can of compressed air (the kind you get at computer supply stores) and blow it into the vents once a month...you would be surprised the amount of dust that accumulates inside them. i think they require some maintenance. in my opinion they are excellent lights compared to the aquaticlife junk i dealt with when i first bought lights...but thats a whole different story. i should knock on wood though after saying that i have had nothing but good luck with kessil lighting and if these ones go down on me i will replace them with kessil's as well.
