I figure there are a lot of Kessil users here on R2R. Am curious, with regard to the A360WE, what folks experiences have been with longevity. I have a bunch of them on my system and have not been particularly happy with them from a reliability perspective. Kessil is very good about the warranty (and I had two fail under warranty), but I've now had my first fail outside of the warranty and am trying to decide how to proceed. 2-3 years from a $400 (now $350) light just seem quite poor to me, but perhaps I am just unlucky. I clean them out regularly. Anyhow, would be interested to hear how long folks have been running these lights and whether you have had failures. With the X just around the corner, I've no interest in a new old 360 for $250. Or even whether to continue with them - even though I do like the look they throw in my tank.
