After talking a little bit to Mr. Harvard and doing two full days of research on the in question leds the remaining concern is still there:
The reliability of the driver-
the leds themselves while not CREE status will usually be good enough in less demanding tanks ie ones not 30" deep trying to grow high quality sps at the bottom....
Second thing is they are cheap enough that you only really need them to last 2~3 years....
the PAR ratings seem to be good enough to keep almost anything happy but you wont get like 500 PAR or anything but most SPS do well at around 250 PAR so there is no point of having 500 PAR....
For the price no one beats them ( a similiar CREE setup would be double if not more)....
So just bare in mind you might be buying leds again in 2~3 years but also keep in mind LED technology right now is like computers in 2~3 years the technology will have advanced so much more that there is no point in buying top of the line unless you absolutely need the higher par ratings which most ppl (not trying to have a massive high-end sps pro-system)
The only thing I cant comment on is the long-term reliability on the drivers....
but even if you add the cost of a new driver set (ie 2x brandname drivers) later on down the road you will still be saving money...at least of the 12~24x setups I was looking at.
Hope this helps.
