Moonlights - white or blue?

[ambaratur]

Is one color more recommended than another for moon lights?

If you have a choice would it be white or blue?

I like the white because it reminds me of the clear nights in the south Pacific. I'd look at it like we look at Kelvin for our tanks. Some would say the blue light would simulate a deeper water, It's preference in the long run. TinMan

It really is preference. I like blue, because' i have blue.

I have white and it seems more natural to me. The water movement on the surface casts moving shadows, making it look very beautiful at night.

I guess I was worried that if they were white it would just look like a very dim aquarium light - and not like a real moon light. But I guess the point is that if it is deeper water it would be blue but more shallow water would seem more white.

Thanks for the input folks.

i had blue before i upgraded my light fixture that now has white, i liked my old blue ones better.

I went with blue, just for preference

It is personal preference, I like blue. Have also used purple which was pretty cool looking.

Moonlight is just sunlight being reflected so I would assume that the blue light is more natural as it is the spectrum that would "travel" the farthest from the source, to the moon, thru the sky, and into the water.

ROYGBIV

Wouldn't the violet/purple light travel the farthest?

I am adding both to my new SPS tank. That way some nights it will be blue, others white, and once in a while both.


Anyone know how to make my AC3 do random moonlights that won't dim?

Gremraf, I thought about setting that up for my tank but it is was not going to be random. It was going to be setup on the lunar cycle.

Use the statements:
Mon 000/000 Then BLD ON: This turns on the blue LED's at moonrise and turns them off at moon set; this would be with just the blue moon lights on.

Mon 120/-120 Then WLD ON: This turns on the white LED's at two hours after moonrise and turns them off at two hours before moon set; this would be with both the blue and the white moon lights on.

Now if you did not want the blue and the white LED's on at the same time, you could add the statement:
If TMR WLED = ON Then BLED OFF: This statement will shut off the blue LED's when the white LED's are on.

Also, on my tank, I have the statement:
If TMR VHO = ON Then LED OFF: This keeps my LED's off while the VHO's are on. I am prety confident the energy used to execute this statement is than less what is needed to run the LED's when there is not benifit for there use...VHO's are already on.

BTW, if you use appliance modules and not light modules, they only go on or off, no dimming. This is what I use.

Also, if you do not want to use the lunar cycle and instead want them on when the tank lights are off, and the tank lights are controlled using the SUN...ON Commands, you can use the SUN...OFF Commands to turn on the LED's when the main tank lights go off.

SUN 000/000 BLED OFF
SUN -120/120 WLED OFF
If TMR WLED = ON Then BLED OFF

Thanks for the info, that will make it easy to set up.
