Thought it would be a good time for a follow up on my lights (36" freshwater bright). I purchased mine in October of 2012 and so far I have had no burned out LED's or any issues that way, so very happy with the longevity of the product. I still see an issue with both lights not being 100% the same color/output (post#151 & 153) on my 210g. It is weird but on one side of the tank I get a strange fast green algae build up on the plastic plants and even on the gravel. There is almost a line of demarcation so to speak on the gravel where it will grow and then stop where the other fixture begins. This is strange stuff! I have had no one notice the color difference and probably could not see it in a picture, so they are really close enough that it is not an eyesore but enough that like I said you get the weird algae on just the one side. This tells me that at some point a different LED was used in production. (Ive had the tank set up for years and it has never got any algae issues like this until the new lighting)
I also have a unit on my 56g column (24" freshwater bright/post #158 picture) that is like the 'good' side of my 210g. It has not shown algae growth or any issues. Very happy with that one!
I replaced dual T5 HO fixtures on the 210g, and know I am saving a ton of money in energy and overall am very happy with the longevity of the product but do question the consistency and quality control. Overall I still think these are a great budget light that are worth the low price they ask.
