just bought a 90g LED
kit from them and put it together adusted the drivers and wow these things are friggen awesome, they are bright and the color is fantastic.
it may seem hard for soem to do but its really easy to do, i was to lazy to solder so i bought the solderless kits and its simple plug and play.
i haven't put them on my tank yet as it is still not running, my LFS
is loafting on gettign my new top frame in and i've been taling my sweet time bulding my skimmer.
these LEDs are also coupled with a Reef Angel aqua controller which is so far easy to use with the preloaded setups, there are forums on how to code custom function
i recommend both for those serious about the DIY thing, same functions as other high end LEDs and controllers but with the cheapness of DIY, 400 for the controller and 500 for the LEDs, which use the same LEDs as the much more expensive Ecotech radeon
