Dirt/dust will kill these lights prematurely due to excess heat. Unfortunately, the only way to properly clean them is to disassemble them. It's a pain over some of the other options but if you do it, they'll last. The two A360WEs on my tank were purchased used to begin with and have been on my tank two and a half years now. Once they're gone, I don't believe you'll get the functionality back but you can try to open and clean it.
I pulled apart the A160 at the recommendation of Kessil, and it was basically spotless inside(just an extremely light coating of dust, which I cleaned while I had it apart). I always maintain my equipment, and especially so with the 160 after my 150 failed. There's a can of compressed air in my stand just for the purpose of regular blowing the dust out as recommended by Kessil.
It is what it is, but it's also frustrating. I've read enough forum threads and reviews to know that I'm not alone in this issue with the A160. With a one year warranty I guess it's not surprising that issues start popping up after 2 years, but it makes it feel like LED isn't quite as economical as they would have you think since the fixtures (especially Kessil) aren't user repairable in any way; once they're dead, you chuck them and buy a whole new one.
I understand the frustration. I am a bit surprised it was very clean inside which makes me wonder if the fan wasn't operating properly. Cleaning them out with compressed air cant keep the heatsink clean which is why they have to be pulled completely apart (poor design choice on their part in that regard). One other thing I'll mention is the need to keep the fan stationary while you clean them; letting them spin freely under compressed air or a compressor will damage the fan (this is true for all similar fans such as desktops and laptops as well). Just something else to consider going forward.
Kessil has changed the heatsink and fan on the A360X but only time will tell if that ends up being a better solution or not (I hope so as I've already started converting over to them).
Their warranty is actually 2 years for Canada (if you demand).
They tried to give me the same excuse because I live in Canada too. The fan stopped on mine.
They tried to say it was because of Europe mostly runs on 220v ..when I pointed out the Canadian and American grids are intertwined and both run at 120, they relented. Full replacement, I only had to pay shipping.
I have had 2 360's for 4 years. Just blow them out with compressed air once or twice a year when they are cool. Also, from the previous page, my 160 works like a charm. Freshwater shimmer!
Just got a pair of A360X Tuna Blues with the new controller. Mounted them from the ceiling using a "y" cable from Amazon. No tank brackets as my set up is peninsula. Tank will be 245g freshwater Mbuna Cichlids.
I started programming the Kessils using the controller. Questions I cannot find answers to...
1) Are the manual effect (clouds, storms) etc. just that, manual only? Meaning you cannot add them to your program so that they occur randomly all day over time, like with the GHL Mitras? If so, boo.
2) Can you determine the Kelvin (color temp) of you programmed color and intensity setting, again like that of other LEDS, like the Mitras? If not, boo again.
3) They say that the light range (Tuna Blue) is 10K to 20K (or so). But there is a Violet Red and Green LED that can be varied in intensity as well. Seems that this may make the light more white, and lower than 10K? Again, it would be helpful to have the controller reflect back to you the Kelvin in the program.
4) What is the purpose of the Group setting? Seems unnecessary from what I have used thus far. I have both lights in synch varying in color and intensity over a 24 hour schedule, with the 8 time increments that are allowable. While 8 seems low, compared to the Mitras, it is sufficient for my needs on this tank.
