    I got a question. Im having my fixtures with 12 NW and 12 RB on each of 3 heat sinks. I can mix and match CW and NW for spectrem at will, but what can i put on the RB drivers. I see other colors nee 700 versus the 1000 the RB are on.

    You can include RBs or Blues (max of 700mA) in the same like with other whites, but you have to adjust the current to 700mA. So as long as you run the white LEDs under the max current, which is 1.5A, it should be fine. (Im referring Cree XPs here)
    Did I answer your question?

    I though RB's ran at 1.0 amps not .7 and whites were 1.3 .... is there a chart somewhere lol?

    Oh no, my bad..
    RB and Blue are max of 1.0A
    Whites are 1.5A.

    Here is the link to the data sheet PDF from the Cree site.

    Id go with them. But what I used is 398nm and 420nm.. (not that I can tell the difference by looking directly at them) from different sources.

    Reasoning? Just precision so you know that wavelength you are peaking at?

    What I meant to say is, it says "390-420nm wavelength." Its kinda wide range, indicates that the spec being variable from batch to batch.
