I bought some blue LED's from ebay and it said plug and play so I expected them to be hooked up to a PLUG. well they are in need of some electrical work.  what is the best way to wire these up so I can run them as my night time lights.

Lol I would have assumed that as well. Are they 12V?
Oh that will be so cool when you are done!

I have a set of those. I think they are still wired into my 125.(above the tec5 fixtures. ) Not the easiest things to set up. I ought to pull them out and sell them. I will look tonight and post a picture of how I set them up.

I will defantly sell some out. I have 40 and I assume I will need 20 for my tank.  or so....
Any pics or wiring diagrams would be GREAT! I will check to see if they are 12 volt.

You'll need to figure out how many mv you need and buy an apropriate 12v power supply from radio shack etc to run them.

The cheapest transformer for those LEDs is at the DI.  All DIs have bucket loads of old "wall wart" style transformers.  Look for on that is 12 V DC output and the most ma (milliamps) you can find (500 - 800 ma would be great).  You shouldn't pay more then $0.50 for the transformer.  Then wire all the LEDs in parallel with the transformer (i.e. they all see 12 v).

Those will be 20mA each and need to be wired in parallel.  By the specs they will be very directional so you will need to spread them out and aim them properly.  I would look for a different solution if I were you.  There are a lot of LEDs out there that have a much wider beam.  I would at least try one before I hooked up the whole array.  Do you know what color temperature they are?  If they are too high in the spectrum, you won't get the glow you are looking for from your corals.  You want 460nm or less if possible.  I have a bunch a that are 455-465nm.  The DI is definately your best choice if you don't already have a wall wort lying around.  All of those LEDs together would take just 800mA or .8 amps.  That should be very easy to come up with.  Be sure you hook up the correct lead to positive on all of them.  It should be the red to + and the black to -.  Good luck!
