![]() So Ive been looking into building one for my tank but wasn't sure on some things. I've noticed that the the Current USA Satellite Lighting systems use white LEDs and those look amazing. Why does everyone use blue LEDs?

![]() I just bought this great string of 120 LEDs, 4 feet long, for $25 at Lee's Electronics in Vancouver today. All you need is a 12 volt transformer to hook up to it. The LEDs are completely sealed so water and humidity are not a problem. It gives great full tank coverage for me and boy do the colors pop! A great low cost alternative to the Moonlights at $18-20 for two LEDs.

![]() as far as the blue leds are concerned i would think that its not so hard on the corals and stimulates the night time moon as the white Leds would be brighter..and the corals don't have a chance to sleep and regain strength to grow...IMO the white leds are just for our own enjoyment to watch the tank in a brighter light...

![]() I have the Current Outer Orbit and it has both white and blue LED's on separate plug ins. I only use the white if there's something I really want to see at night. I suppose if you really got into it, you could time a 24 hr period more accurately and could also simulate a full moon once a month.
To be honest, the blue ones are the ones I use every night. They do give a really nice effect.

![]() if your wanting to actually light a tank using LEDs seems the trend is to use a 50/50 split of cree XRE royal blue and white to create a 14k look.
http://www.ledsupply.com/ for those that are DIY minded they are quite powerful especially when coupled with a focusing lense they produce very very high PAR numbers. tighter the beam the higher the comparison to MHs. if you want to look at building your own nano-reef.com in the lighting section has a ton of articles and threads about builds and how to do it. so far alot of success for total tank lighting. also you get the shimmer effect of MHs some say even more so then a MH due to LEDs shimmering already. |

![]() They carry the same ones at Wal Mart too, can't remember the price off hand, but would assume cheaper than Petland sells them for.
