    The color temp looks way too low. It would be very yellow and you'd have the same issues as any other lighting format with that color spectrum. They also seem kinda large physically.....

    My 2c worth.

    Cheers

    Sorry, missed the request for info....

    3W LEDs are the norm.
    Go for Cree XPG/XPE etc. I say Cree specifically as they are a known entity. Others are available but they are less documented.
    The main colors used are :

    Warm White(WW) neutral white (NW) Coolwhite (CW)
    Royal Blue (RB) Blue(B)

    Batches are the intensity of the led's.....basically different quality within the same type( think its to do with tolerances in the manufacture)
    So basically a Cree XPG etc can have different strengths depending on which batch it's sold under.

    The colours are made by blending these basic individual LEDS
    The drivers are what interfaces between the mains power and LEDS
    The common brand of driver is Meanwell.
    If you want to control sunrise or sunset with a controller then you choose between either an analogue 10v driver or one with PWM (pulse width modulation) that's what the 64-48 thingies are that every talks about - a Meanwell driver ( or Power supply) whose product number is 64-48d (analogue) or 48p( PWM) this is chosen by seeing what type your controller supports

    They are mounted onto heatsinks because they don't radiate heat like bulb but dO get hot so you dissipate the heat.

    Now go to Rapidled.com etc and have a look. Hopefully it'll be less gibberish now.

    Please correct me if I'm wrong on anything guys

    Do you need a cooling fan?

    I think it's it's only if the heatsink the LEDs are mounted on can't take the heat load. I would do it as a safety. 60mm and 80 mm are the recommended and are cheap from computer stores. The bigger the fan, the slower you can spin it so less noise ( again, that's my experience/ understanding)

    Colour temp is wrong - I just got some nice ones of the net...20000k.....corals are loving it compared to my old PL tubes.....

    Search for "3w high power led's aquarium" - you will find loads of places selling them!

    I agree with EFJ. The ones that seem to be working the best are DIY, or the REALLY expensive units like the Radeon etc. VERY cool but pricey.

    The only other thing I've seen are the PAR38 bulbs. Seen some Nano's with them but again not much info. RapidLED.com sell them, haven't found them locally, sorry to any sponsors if you have them- buy local if you can;)
