    Anyone tried these led's.

    Hi folks,

    New guy here. Has anyone tried these led units?

    http://www.ebay.com.au/itm/New-12W-2...1ee5e9b&_uhb=1

    I know that they wont be the most efficient lights and that they are a bit blue (I would block out most of the blue) but do you think that they could be useful or a waste of time?

    I'm considering using these because I want a low heat light and I don't have the technical skills to easily DIY leds. Also they suit my budget. I'm considering 4 to 6 of these for a waterfall scrubber.

    Thanks.

    I use these:

    http://www.ebay.com.au/itm/10W-20W-3...e&talgo=origal

    the 30 Watt size.

    What you are looking at probably will work. I looked at the listing and I don't understand what the wattage is. At one place it says 300W and another 12 Watt.

    I think what you have there is an array of 6 LED's with a total of 12 Watts.

    These units are fairly waterproof. Not totally, so don't put them underwater.

    I have some issues with these strips.

    1. They are not waterproof or water resistant like the others we have been discussing in this thread. This means you have to place them so they shine through glass or in an area that they DON'T GET WET. . Spray will eventually short out lights unless you have them sealed or away from the spray. I learned this the hard way.

    2. They are 1 Watt LED's. My experience is that 2 or 3 Watt LED's work better. The write up for this one says that the seller has had success using them for algae scrubbers.

    They may work fine.


    Algae Scrubbers are a fun part of reefkeeping.. You get to play with saltwater and electricity at the same time.

    I've just ordered 4 of these in 12w with all 660nm LED's for a double sided 20 cm x 20cm screen scrubber. I'd imagine that Ill have to position these a bit further away from the screen due to the tight packing of the LED's. How far should I space them from the screen? Any suggestions would be appreciated.

    Thanks.

    position them about 3 inches away from the screen to start.
