    if you want a fish only tank then by all means you can use these, but not if you want corals, send them an email and ask how much watt each led takes. They say that 1.5 meter is equal too 15Watt, thats the first warning point. I really doubt this is a good light to use for an aquarium.

    Cool I have a 1x1 meter "cube" that is 500mm high, and a 250w MH.
    Would the 20000K blue led unit make the corals colors pop or would it be a waste of cash?

    I replace one every six months. never change both at the same time. it shocks the corals. if you havent replaced them for a while.replace one now and then one in a monhts time and then one every six months. Or thats how I do it. the lights aint the best so its best to replace them often.

    well find out exactly what LED's they use in the strips and i can give you some advice, my thoughts though is that the metal halide will overpower these LED's very easily

    I have spoken to them and they say that they already have clients with sps tank using them, so harsh to say it wont work as none of us has used these or tested these. I am waiting for the new stock to arrive and im going to try these. People also used to say that you cannot have sps corals or nemmies without metal halides and i have both under t5 lamps. Testing will prove if itll work or not. LED's has also been used extensively on sps tanks so who knows. O yes and seank also has t5's on a 1,3m deep tank with various corals, so lets test and see first.

    No a 10k or 20k output is a 10k or 20k output period.

    When i said these wont work i only went with the specs. Sure they might have people with SPS tanks using these but maybe its just a moonlight?:whistling:

    Dont mean to offend, but LED's are the only thing in reefkeeping i am really good at so yeah.

    Sorry but Johan is correct.

    Probably used as moonlights. Unless they have a SUPER shallow tank (30cm) and covering every square cm of the surface with these.

    My reason:

    320lm per meter. That's shit to say the least.

    A SINGLE Cree XP-G LED gives you 493 lm. Thats 92 lm per watt. (Cree's are 3w)

    The strip you linked consumes 22W at full power per meter. That's 14 lm per watt.

    Kelvin is simply a measure of colour. Just because its 20000K or 14000K doesn't mean it will grow corals.

    Flux, nm, ect are all important factors to consider.

    As a Fish only tank, sure, SPS... lol

    I'm not busting your bubble, just saying that you'll be wasting your $$$
