I am using the chinese knock off's of the orphek or3's
They look like this and can be found on aliexpress.
They are pretty close to the OR3's, but i am using it to get more sparkle out of my corals then actual par. So mine are not tuned all the way up, and i have the one with UV mixed.
So far i like them a lot.
As for how long they last, i'll let people know when they start dying or have problems.
Oh the controller has memory when power goes off, and does not reset the settings on the dimmer which is a even bigger plus.
