    Can any of the LED gurus advise on whether these dowlighters are suitable for reef use and how many of these 3W will be required to equate to say 6 T5's. They are also avalaible in blue as well, I would assume one could inc. for viewing pleasure.

    I asume these are the 220v ones

    and these are the 12v ones that will require a transformer i presume. Could one use 12v ones? will they be equvalent to 220v i.t.o of light output but on less voltage.

    Specifications:

    Available in Pure White, Warm White and Blue LED’s
    Approximately 50 000hrs continuous use
    Low power consumption
    Current consumption: 280mA
    LED Lighting lumens: 280 approx ( = 30W Halogen )

    E14, E27, GU10 only available in 110V & 230V/AC

    I have these in my home.
    Replaced the 50W down lighters I had when we bought the place with these.
    9W of those 3x3W in pure white is the equivalent to 90w Metal Halide but you need to look at the colour spectrum. I wanted to go this route before my LED build but you need a mix of blue and pure white to give your tank a nice look, else they give off a yellow colour in the water making it look kak.

    Yip.
    They plug right in, no probs.
    PM me as I have a connection for these in 9W instead of 6W if you are interested.
    They kick ass and I saved almost R1000 on the electric bill after we put them in.

    Spots in my entertainment area where the tank is....

    @ Quintin pls let me know where to get these 9w ones. I am in Zululand and the chiller is running me out of this hobby. Not even fans over scrubbers seems to make a difference.

    Yip.
    Remember colour fades under water and the deeper you go the more colours start vanish.
    Red is the 1st to disappear, blue is the last....
    But give it a go.
    You may have better results.
    Have a look at this link LED My TANK! « « ReefLEDLights | LED Aquarium Lighting ReefLEDLights | LED Aquarium Lighting
    "The neutral whites cast a heavy yellow tint to the tank which then needs to be combated by a larger ratio of blues to whites.
    The following picture is showing how yellow it can get with cool whites. Adding neutral whites to this increases the yellow"

    maybe do some reading on the forum about LED lamps , and lights , there have been many discussions about this topic , and most of the time , no one is able to say if the LED are suitable for reef systems,
    obviously they can be used on FOWLR systems , but with corals , it becomes a little more tricky.

    i think the main reason why this is so , is because LED , is not a light as per say , and therefore the penetration of the light spectrum through the water differs from usual T5s and MH .

    sorry Quintin.....a bit off subject...the tradition down light 50w cost R20....6w Led cost more than R300 .....9w even more....IF i did the sum...how long to use and recoup the R280 over paid and start save the money. that why i didn't buy the 6w led down light replace my old 50w.
