Thanks, i'm planning testing the dimmable and my optics once i add more corals such as sps. It will be Interesting to monitor the growth compare to mh. Yup, it should last more than 3 yrs.
rygh said:I bought a set of cheap drivers from dealextreme - took forever, and really poor quality.
I am not sure I will use them.
Definitely like the usual vendors mentioned above.
Plus www.cutter.com.au - the only place to get bin sorted XP-G and XP-E. Only took an extra week.

With decent cooling, and running at such low power, I would expect a lot more than 3 years.
BTW: What you can do since the power supplies are dimmable/adjustable is increase them
by about 3% per year. They degrade fairly linearly. Especially easy if you have PAR/LUX measuring tool.
