Ill try to get some pics then I get started. (btw 100 Blue LEDs 12 bucks pluss shipping) Now I just need a power supply. I can proly get one of them for around 15 bucks I hope. Wire, dirt cheep. Reistors (already have some). Now if I can just get my butt out from infront of this computer... :yes:

Wow thats a great price if they are SUPER BLUE. If you just look at the bulb does it look clear or like blue glass or plastic. IMO the super blue 5mm leds that will look clear if you look at the bulb with it off are the only ones worth useing. The right spectrum wavelength at 470 and intensity to shine to bottom of tank. Good luck.

Well the moon lights are done now, They look awsom! If any one is interested ill do a run down. They cost me about 20 bucks all in all, and fit inside my corlife light fixture. I may not know much about fish tanks lol, but I know a thing or too about wires

I have a coralife 48 inch fixture and would like to know more about adding moon lighting. Can you give us a diagram and pics to go along with your process?
Thanks,
Nick

I got them from th-e bay, just do a serch for leds and im shure youll find them. They are from china, cheep stuff over there. As for diagrams and pics.. I dont have a camera that can take good pics so Ill link some sites with helpfull info. If any one has any questions after that ill be glad to help.
http://www.theledlight.com/ledcircuits.html <-- this spot should fill you in on how to wire them up.
this one too -> http://www.theledlight.com/technical.html
Try this for your resistors -> http://metku.net/index.html?sect=vie...calc/index_eng
you want to line them up in a "Parallel" configuration.. the first link should explane that
for a power supply you can get one at radio shack for like 15 bucks, its a 120AC-12DC converter. The one they sell there is White and is like for chageing cell phones and what not.. but it matters not as long as its puting out 12 volts DC. (less would be ok but just get a 12er) Dont be scard of the wires on it cut um off if you like.. I just soldered my wires right into the pos and neg holes on the plug it came with. Each led will need 3 volts or so (it dose not have to be exactly 3 volts just not more then 3.8 or so, it can be less like 2 will still work)
SO, 12volts comeing into 2 wires (one black, one red makes it easy) Solder your resistors (I used 510 ohms that came with my LEDs) to the positive leg of each one (however many you want, I used 6 total) and then Conect them all in "PARELLEL" (see fist link) When your done it will look something like the last pic on the page of the first link up there.
I also used some sillicone gell to seal up the solder joints keep every thing ship shap. You could juse use Electrical tape and be ok though. Once I had the lights strung I just tucked them in woith my corlife light next to the bulb. No probls with over heating or anything however its only 65 watt. With something hotter you would want to mount them differantly. You could drill holes in the plastic and poke each led out of one whatever you want to do... mounting is the easy part any how... well its all perty easy.

Led light works a lot better bulbs, it even looks good. Just consider it as Audi to Fiat.
