Blue LED vs White LED Moonlight

[Fenix]

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?

Its supposed to simulate the moon. But why white over blue? Don't know

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...

does anyone with white leds use theirs 24/7?

why white
if you want to go with blue i have a couple that i could give you,
it could be easily rigged with any dc power supply.

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.
