Anyone messed with the High Intensity 3W LED's?

[Arkangel77]

I was wondering if anyone here had tryed these in there tank and what was the outcome?

Something like this http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=280346782433&_trkparms=tab=Watching Type of LED????????

They look interesting!

Don't buy it from there. Check this, it is cheaper and more specs:

I have been thinking to try High power LEDs, but I am busy with school-work now.
Don't forget that connecting a number of them to a single supply will require balancing and current limiting circuit.

I wouldnt touch LEDs yet, LEDs are still not at the ease and price that T5HO offers. Plus these kits on ebay are incomplete and need a driver (power supply) before they can be used on aquarium.

Thanks for the link, I am going to have to do some digging. I wish there was a How To Link somewhere and there may be - I gota look. I am Verry intrested in doing a row of these on my tank and seing how they look. I have seen other posts about it and the results were impresive! I guesss its time to use that search function again - LOL:wall:

There are some good resources and build threads on http://www.aquaticplantcentral.com/forumapc and http://www.plantedtank.net/forums, might want to try there too.

Also search for threads by Corykeeper, he used to preach LED lighting quite a bit.

I read threw this one http://www.fishforums.net/index.php?showtopic=264895 , I need How to For Dummies - LOL. All the links in that thread are not working and that dont help me ether. I need to kinda see the part to try and understand it. I guess I am tired and that may be part of my problem LOL. I am concerned about the heat also. I have cooling fans but stoped using them once I swapped over to regular LED lights. These High Power LEDs intrest me because theye are SO bright!

Are you mistaken? Ebay has 5 for $13 meaning $2.60 each
Mouser has them for $7.13 if you buy 100 or more.
I don't see how that's cheaper.
Quality of LEDs isn't that different "good" or "bad" like other electronic if you find some that have the intensity and color you want, buy the cheapest one available.

Here's a expriment comparing the grow rate if plant under LED and PC light for those who want to read (7x1watt Luxeons vs 1x7watt PC (Azoo palm light))
http://www.aquaticplantcentral.com/...s/1009-diy-led-lighting-via-luxeon-stars.html
For those who don't wanna read, it's summarize to this: the growth is quite close with LED has a little better growth.

LEDs are really cool.. and will work well

just plan on spending a lot of cash to get them up and running

And yes LED is current a little on the expensive side if you buy them pre-fab.
If you have some time, soldering skill and a local surplus electronic store, a LED lighting system for a 55G will be around $150.
