    Hi guys

    A LED manufacturer paid me a visit today (job related) and I was given a working set (on loan).

    The temptation is way too great to resist... how can I stop myself from testing it out on one of my planted tank?

    Here's a closer look at the LED module.



    It comes with waterproof (IP65) housing... 0.55W per module

    Here's the ballast. Each of this ballast will be able to support up to 50 LED modules. It's very sleek and waterproof too



    Sorry I can't reveal the brand name at the moment.

    Please note that I am not doing a review for the manufacturer, they introduced me this product for outdoor signage application

    Must test the LED on an existing tank So I chose my Betta mandor tank (paludarium) to conduct the experiment



    I was given 6 modules in total. So I use 3M VHB transparent tape to stick the modules on top of my existing light casing and hood. Don't worry, the 3M VHB is very reliable

    Ready to see some tank shots?

    Both pix taken using the same settings on the camera. No brightness adjustment.

    ORIGINAL
    Using 13W PL


    LED
    Using 6 x 0.55W LEDs


    Alright the LEDs are not as bright as the 13W PL. But with 13W, I can fit in 24 modules

    MOntfort tank is currently running on 200 leds with no ballast. Results are so far encouraging. Even though the tank light set has got 4 pl tubes fitted, they are only on once or twice a day. The LED is on 24/7 and we don't have problems with algae. Cyrpto parva, wenditti, nana coffelia and many other plants are doing well even riccia.

    I would be there tomorrow and tried to take a photo of the light set.

    here's the thread on the project. http://www.aquaticquotient.com/forum...ad.php?t=39996

    Jervis, wonder what is the colour rating for the LED lights? 6500K? Is it a full spectrum LED? I wouldn mind using this for my tank.... it looks much more 'prettier' than the normal lights... at least to my wife haha dun wan her to nag me for not having a 'not so pretty' tank

    In the other thread, the single leds are supposed to be 6500K

    daylight white, cool white and warm white leds are currently available. in early days, manufacturers strive for 6500k daylight white leds.

    white led is not a full spectrum light. it is basically a blue led with a yellow phosphor.

    You can try mixing them just like how we mix out T5 tubes. The cool white LEDs I'm currently using doesn't bring out the green very well... the plants just doesn't look green enough

    Yupe I believe so... or maybe mixing White with Amber, more white less amber.

    An update... all plants are doing well actually

    An update... been slightly more than a week I filled the tank and added a wide variety of plants (from other tanks) to test the LEDs. Sorry no scaping for this tank

    Lighting duration is 10 hours daily.



    After 1+ week... most plants are looking quite encouraging... in fact I do not see any sign of stress (or algae)... all these for a total of 3W!!!

    I got 5 of the LED modules from SLT. It seems that only one shop sells the product. It is on the top floor on the left side area of the escalator. It retails around $16 each

    Ballast needs only a small one will suffice. I got a 10-60W 12V ballast about 10-12 cm long only. It retails around $8.

    Unfortunately, the shop only sells cool white coloured ones. Attempts to get other colours seem to be hard as they don't seem to want to bring in small quantities.

    Will update again

    @ patricc,
    Do they happen to have blue LED modules?

    @ Jervis,
    What's the wattage on your modules?
    The new pictures seem brighter.
    Did you do a white balance?
