I just ordered 2 dimmable Taos on the recommendations of many people on this forum many of whom have decades of experience and are running rather large systems. I am very confident that I will be happy with them, but I will post more once I actually get them running. I am replacing and aqua medic fixture with 2 ML and 2 T5 actinics.
BTW, I have seen many people post link to them for sale on amazon. That is where I started and they were $189. I searched taotronics dimmable. I noticed the seller was Complete Filtration Services Inc. so I googled them and found there yahoo store which had the same lights for $165 with $0.99 shipping.
I can't believe I am lighting my tank with led
