    ok
    here we go
    got the LED from here http://www.led-lights.co.za/lumi-shop/waterproof-flexible-strip-light/ the Elite white
    [​IMG]
    got 5meters of it one to short dum of me :violent1:
    well now i have to go back and get more and more :wave:
    ok so fore the mounting was a bid tricky bud got this idea :evil6:
    [​IMG]
    [​IMG]
    the driver
    [​IMG]
    the first test
    [​IMG]
    then wiring of the 3x 36cm tanks
    [​IMG]
    the power test
    [​IMG]
    and then i sow i o got 1 meter short so i goed only do 1 90cm tank
    [​IMG]
    and here is the before all have 20w cfl Philips the 36cm tanks had 1 20w cfl the 90cm 2x20w cfl
    so here is the 36cm before and after
    before
    [​IMG]
    after
    [​IMG]
    here is the hole rack before
    [​IMG]
    after
    [​IMG]
    and here we have the 2 90cm the top one is on 2x20w cfl the bottom LED
    [​IMG]
    eck tank has 2 strips
    hope u enjoy

    lekker build wolf. Just a fair warning on those LED strip lights, they loose their brightness after a while, not sure why though.

    How many watts do you think you have over each tank now? Any sign of pearling?

    I plugged them in last night.
    Don't think they wil pearl as i still see is as low teck tank and wil not ad CO2.
    The LED strips is 5w per meter and i have 45cm x2 on the 36cm tanks 4.5w over a tank

    Can you share the cost ?
    And what is the maximum water depth penetration for those?

    As for the longlivity of these LED. The killer "or so i was told" is heat. The diode gets to hot after long hours of use
    And this wear them out. To acheve such brightness reqire more elect to be used thus reducing their life.

    Aparantly the manufacturers "supercharge" these for short bursts of high bright light. Not Intended for long regular hours use as we do.


    Note... i was told this. Can not confirm it.

    look on the site the cost is there
    i spend r2000
    WATS the killer is the driver i can use one driver on all my tanks bud the are split on opposite eds of the room
    i deed a nether meter to do the res of the 90 cm
    and if i want i can dabble my lighting with no extra cost on power as 1 30w driver can lid 5m they say 6m bud as i was inform leaf 5w fore the wiring :laughing7:

    Very nice.

    Perhaps start a new scape on one of the tanks so that you can see how the plants grow from the 1st day.

    thees tanks are fore breeding
    i only grow mos fissedins and so on in them, nothing demanding
    will how ever make my 60cm LED bud then i will use the 14000k and the 7000k LED mix them 3 7000k and 3 14000k LED. is going to be a pine to solder the 3 LED mix

    Re: WOLF'S LED DIY

    This is the cause, but Wolf's are newer LEDs (I think they are type 5630)

    I guess the tank is about 25 cm wide? This would come to about 50 W/m2. Given the LED optics this is as good as 150 W/m2 so if you give CO2 you should see pearling. Give it a try and let us know. Also, put in a few sprigs of Rotala macrandra, I'm curious to see if it grows well under the LEDs of that wattage.

    These are my garage breeding tanks. I dont want co 2 in there.but when my other 90cm is up and ruining i will. Rethink the CO2 story.
    I do want to test these LED at hi teck in my 60cm tank was thinking 4rows 2x 7000k and 2rows 14000k.
    And tanks are 46*32*30h

    Re: Re: WOLF'S LED DIY

    the maon reason this would happen is if the leds where being driven to hard. Most leds have a sweet spot. And if you go past that to achieve more light out of them they just dont last. Think of it as driving your car and revving it into the read every time. It won't last long.

    I seem to have misread same info the elite LED what i have needs 10w per meter
    We suggest a design capacity of 5W/m for the eco strips and 10W/m for the elite strips
    So my 2* 90cm tanks that use 800mil *4 LED needs more power.as they are 3200mil long and has a 30w driver wander if that 200mil is going to be a problem.
    But the 46cm tanks that use 6*450 are in range.

    I have a problem
    Hair algea in my top left tank my galaxy rousboras breeding tank, i think the LED is to strong.

    Ok now i am ready fore step 2
    My 60cm
    Now the q is do i use 4 LED strips or 6 strips with 2 strips being the 14000k one's
    Thinking of 4 strips of 50cm long that's 2m LED strips and 20w LED light
    Or
    Do i do 6 strips of 50cm giving me 3m LED and 30w
    And how the hell do i mound them hanging?

    Quite possibly... Or its just bad luck. If my math is right then you are providing a lot more light than before (with the CFL) and you plants are probably in need of extra CO2 to properly use the nutrients. Maybe dim the light a bit? I see one can buy in-line LED dimmers by which you can manipulate the current.

    About the 2nd question, what is the dimensions of the 60 cm tank? Standard: 60 x 32 cm? If so you need about 13 W over the tank to bring it upto 200 W/m2 of T8/T5 lighting. Considering the narrow beam, I would try spread the LEDs out in several rows to try get even light distribution. If you are using the Elites, this would be 1.2 m of LED, so perhaps 3 x 40 cm or 2 x 60 cm. I would go with the 3 x 40 as if you have the LEDs right upto the edge of the glass you may lose some light to reflection against the glass.

    Are these 120 o beam angle? If so, then for every 1 cm above the water the beam will spread out 1.7 cm in every direction. This means that at 5.8 cm above the water the beam will have a 10 cm spread, so a 40 cm length of LED strip 5 cm above the water would have all of the light directed down on the water and none on the glass sides.

    Isn't geometry fun!:occasion18:

    Hope this helps.

    Wow this helps allot
    Ok the 1q I wil just drop the 9 oues to say 7 anf use same exel.
    Q2
    I will use 4 strips 8cm above the water i will make a stand and yes they are 120 dec lens. So 6 will be over kill ? Yrs the tank is 60x32x32
    The idea is to use 4 strips of 500 long 10c above tank.
    That is 20w LED as x3 so that is 60 w
    I now have 24x2 48w t5 on there
    On this paper LED seem more then.
    Thanks fore the reply

    Today i got same more LED fore my 60cm and my 2 x H2O tanks
    and got same perspex and aluminum strips to help with the heat
    use same real strong glue same gorilla quick tight
    got my self the 14000k LED this time so will be using them and the 7000k LED
    on the 60cm i use 50cm x5 2x is the 7000k and 2x 14000k the middle one is 3 LED 7000k and 3 is 14000k and so on.
    on the H2O tanks i use 43cm 7000k 2 rows. and 2 rows of 25 cm 14000k LED(split in 2)
    had my 60cm on fore a couple of minutes and my bamboo plant started pearling
    so here are the pics
    will redo all 3 tanks tomorrow.
    now the big q is on what plants do i test these lights on?
    Enjoy!:ky:
