    Thermal Management is Key

    All things equal a fixture using Cree X Series LEDs with a junction temperature of 25 Degrees C is 15% brighter than the same running at 85 Degrees C.

    3 Watt Bridgelux Knockoffs can be at a greater disadvantage due to their design.

    Also...Heat and Excessive Heat does not play well with electronic longevity.

    I have 2 Orphek Atlantik V2.1b. Really like the color, but nothing like what I saw those tanks with MH Radium bulbs. Just wonder if any one here have the Atlantiks and have better results.

    I run the atlantik compact and couldn't be happier.
    Sure these may be no comparison to mh but then we are talking apples to oranges

    What country are we speaking of?
    LED technology has come a long way.
    I don't think i can say a brand is fake. There are a lot of differences in fixtures.

    ive heared that if the kelvin of light gows higher than 14000k the corals do not survive more than 1 year for example 25000k

    Yes lps coral will live a long time.
    14k is a good target but remember led fixtures are deceiving to the eye.
    A par meter will tell you A lot. Do you have access to one ?
