    ok so i got my hands on the pe LED
    here is my findings
    dam nice
    specs
    Elite white lumi is 300 lumen per meter

    the pe one is 6600 lumen for 5meter = to 1320 per meter
    and wen they are on dam they are bright
    they need more power per meter bud dam they are more brighter
    here is a pic

    Have you measured the how deep the light goes.
    Will I be able to use it on a 50cm deep tank and still grow plants.
    Need to replace my 54w juwel light and they aren't cheap. Def looking at rather going LED.

    @wolf , just watch out for galvanic corrosion between the aluminium and your fasteners. Could be a problem if they're often wet, as that adds the electrolyte and then the fun begins :) ( http://aluminumsurface.blogspot.com/2009/04/corrosion-between-anodized-aluminum-and.html )

    Using aluminium fasteners solves that problem. You can also get nicely shaped dome heads for an allen key to make it sexy :love4:

    (and glad to see you're using a cheap adapter to power the LED's!!! Too many people turn a cheap alternative into something expensive)

    @AdrianT we had a lekker boom lifted a plate of Titanium while cutting on a waterjet machine from the aluminium in the slurry giving off hydrogen, gas building up under the plate and the Titanium being the only plate that sparked while being abrasive waterjet cut at a company when I just started working.

    Boss did not belive us the first time when we told him the story until he researched it, luckily he is a metallurgist.

    That's a good example of some super fast galvanic corrosion! The climbers are having this problem with stainless bolts, and mild steel nuts... terrible idea!

    @wolf After going through your thread I wanted to build my own LED light too...

    I just got my LED strip from the Improved Living PE guys, I bought the SMD 5630 5m roll as per http://www.improvedlivingpe.com/#!/...K-Brightest-in-SA/p/39338197/category=5513173

    It's what you recommended and what their site says are the "brightest in SA"..

    But either I'm doing something wrong or these things are just rubbish...

    I connected the strip to a 12V DC 6A adapter and they come on but they are very dim, no where near enough to light a tank (of any size).

    Just to check that my eyes werent playing tricks on me, I held up a portion of the strip on the top of my 4ft tank but it made zero difference, it basically looked as if the lights were still off completely.

    I expected to get at some some light and then once I cut and connect in parallel I was hoping to get great lighting per your post.

    LOL nevermind, it's been a good weekend it seems, my brain is still in weekend mode.... just noticed now that the PSU is only 0.5A (I saw the 6VA and thought 6A)... damn it, now to go searching for a 12V 6A PSU!

    To test in the mean time you can connect the LED strips to your desktop pc power supply. Its the black for ground (-12v) and yellow for possitive (+12v). Some of them are rated at 8A.

    Yes, already using a computer PSU at the moment, its rated to 14A on the +12V yellows.... It is brighter now, but still not where I thought it would be.

    When I then use my multi-meter to test how many Amps are being drawn by the LED strip (the full 5m) its only drawing 1.9A, this I find very odd, since technically it should be between 6A and 10A (max). The 5630 chips are rated at 0.4W according to my research, and there are 60 per meter, thats 24W per meter or 120W for the full 5m.

    So, if we then say 120W / 12V = 10A

    A max of 10 Amp draw... I know that it's not likely to draw the full 10A, but I was certainly expecting it to draw somewhere in the middle - like 6A.

    The fact that it's only drawing 1.9A for the full 5m tells me that it's running at 20% its full power. --- or these are sold with incorrect data.

    Either way, I now sit with an LED strip that I'm not sure will even have any impact on my tank if I proceed with my build.

    :(

    Send it back and ask for a refund. Maybe they packaged it wrong or got the product mixed up in the package. What you have done sounds right and it should be brighter according to your specs and measurments. It would not be the first time that company has done something like that. Just glad im not the only one complaining about them.

    Well, I went ahead a built the project, I must say - what a waste of money.

    It adds almost no value to the tank in terms of lighting.

    I'll post a new DIY thread with pics and result soon and include the link here for those interested.

    I added 2 metres to a aluminium backing to my 3ft tank. If i added all 5 metres it will be too much so i have 3m spare. They sell good power supplies too. [​IMG]

    I do however think their 1w chips are the better way to go. And super brighter
