    That good to no. I have a 17watt RGB LED strip and only switch on the blue and red on 100% when the main light is on. When my light timer goes off i put the RGB stip on dim white so i can still enjoy the tank
    So now i dont need to get red LED's ;D

    No you don't, but it will help if you can improve the R/B ratio of 0.70 of the 6500K LEDs.
    0.70 is (almost) acceptable, but 0.9 is much better ;D.

    The way I understand it is that light predominantly affects the metabolism (growth?) of the plant and in some extreme cases plants won't grow at all if the light spectrum is inadequate in some way.

    The PUR (Photosynthetically Usable Radiation) graph below shows which wavelength of light are the most important and to what degree. This graph also shows clearly that the RED/BLUE ratio of the light source is a very important parameter:

    Summary of my LED Light Phase 1

    1.3m aluminium strait edge found at hardware store used as a heatsink (R120 for 1.5m)
    12 x 3 Watt 180lm LED from ebay (no name brand$20 for 12)
    LED driver from DX.com ($13)

    12 LED’s on this piece of aluminium does not need any extra cooling (but I used water cooling because I am planning a upgrade and it just sound cool 8) )
    12 LEDs seems to give off more light than a 54watt T5 (my observations, if some one in CT has a light meter to test the light PM me)
    You don’t need to use expensive thermal epoxy(R200), superglue(R1) on the edges with thermal paste($3) works
    Used normal epoxy (R16) on the LED and solder to waterproof and secure the LED
    My epoxy dried too fast so I completed the waterproofing on the LEDs with Butanim paste
    The LED light costs me about R400 (with the temperature it is running at now i should loose 30% of light output in about 20years :))

    For the guys building or planning there own DIY LED
    use some optics on the LEDs they not expensive about $5 for 10pcs ure light will be evem more efficent.
    use Ca combination of warm white and cool white LEDs so you have the right amount of blue and red spectrum, @Cor has a document that will help you with the selection, thnks Cor.

    So ~R500 gets you a very good and effective LED system. Ever considered putting some Rotala or something more challenging in the tank to see how it performs under the LEDs? I think you have ample light to grow plants other then Java moss, fern and Anubias.

    i tried other plants but they dont last long in my tank they all get uprooted by my parrot and pleco. thats how i ended up with moss, javas, anubia and bolbitus.

    Dude, this is a planted tank forum... give those parrots wings !

    Did you see my recent post on the T5 VS LEDs, keen to get your thoughts ?

    Is that Hygrophila "long-leaf" in the right corner? If so then you can grow plants which are a little more demanding than Anubias 8)

    Trevor, if you can build a similar array with twice the W/m2 you should be able to grow whatever plants you have in mind. Slagter is running 39W LEDs over a 1.2 x 0.45 cm tank (or about 72 PAR/m2) which is about double what Shaheedo has. I think a similar setup is a viable option for you. :sign13: The money you save by not investing in T5 can be put into buying a nice quantum meter so you can tell how many PPF you are pumping into your tank. :hello2:

    Try Rapid LED they have kits and show you exactly what you need, Tyrone and Greystroke will help you on the amount you will need.

    I'm personally going to be trying out 30 cree(@1500mA) and philips, 24 cree coolwhite and maybe 2 clusters of royal blue+deep red+cyan, on my 1200(L)x500(W)x450(H) in the hope of bringing out reds in plants with the cyan without giving the tank a strange green glow. The reason I'm going cluster the coloured leds is so I don't get a disco effect. I also get the bonus of the deep red(650-670nm wavelength) for plant growth.

    start to order your driver and LEDs it will take about 4weeks to come
    I bort my driver here
    http://lightake.com/detail.do/sku.Waterproof_67mA__9_12_x3W_Power_Constant_Current_Source_LED_Driver__AC_85V_265V__-36498

    If you going for cree LEDs dont use this driver because this has an output of 670mA(you will be waisting muni). cree LEDs cost more and can be driven at much higher currents with more light output,


    I bort my LEDs at this shop early 2011 http://stores.ebay.com/tubelight or shop around at any top rated ebay store LED prices came down alot and there specs went up :laugh: I used 3w 6000k LEDs 180lm

    I also orderd LEDS here http://stores.ebay.com/wellparts/3W-High-Power-LED-/_i.html?_fsub=2959402018&_sid=1001320378&_trksid=p4634.c0.m322


    the aluminium i used for the heatsink I got at a hardware store, ask for "strait edge" its under R100 a meter. you can cut it to 2 x40cm and split the LEDs.

    if you not happy with the results you can always add more LEDs later. I am happy witht he plant growth but not with the colour so i will be adding a bunch of red leds sometime

    Hi Herman just google Rapid LED its where most of the local reef guys buy their leds and they sell Cree leds which are the best atm if you choose a white LED it will show you the recommended driver to use with it.

    I want to add some leds on the side where my tubes end and then also a moonlight kit to use for 2 hours after lights are out.
