Ok just wanted to make sure, I’ll see what’s up again tonight, if it doesn’t come on I’m thinking it may be defective. Thank you for your help

I’m kinda going of memory so keep that in mind, but If you have advanced settings on, you can program lights 24 hours however you choose.
If you turn advanced OFF, you can then set the moonlight function to manual or auto. Setting it to auto will turn the moonlights on based on the current moon cycle.
For example,
A few days ago my moon lights were coming on around 10:30-11 pm and shutting off a little later. Last night they didn’t come on till 12-1 am roughly and stay on until my 9:30 am light schedule starts.

I have dual 11’s over a 75g and I can’t see how the moonlight is too bright. Why light/s are you using? Maybe others have more panels/clusters than me?

Is your moonlight in manual mode in the settings ?

I tried to message you, but the site will not allow me. Can you send me or show me your full Meritian Schule with light percentages?

In the app go to community tab, my schedule is shared as Coral Collector VR

If it doesn’t show up then message me here and I’ll try to help

I Finally received the last hardware needed to hang my new meridians, and I am most definitely pleased!

These things are nice and powerful. I replaced photon v2s with the meridians and am running them currently at 25% less all blues and almost half of the white for the same par at the top of my rocks and considerably more par at the edges and bottom of the tank.
Also the par measurements were taken with the old xho strip lights off but still on the tank and honestly causing some shading. I can finally remove those also!

I’ll look into it, but it likely won’t happen soon since working with app developers is very expensive even for seemingly small things.

We chose cool blue for moonlight because it has minimal impact on photosynthesis at night. If you select other colors based on personal preference, they may not replicate true moonlight and could potentially stimulate photosynthesis, which is generally not recommended

Hi Reefbreeders, I’ve been very interested with the lunar and solar cycle and I think what a lot of the companies are missing is the thought that coral need a light out period which is exactly what your referring to. Concerning the “cool blue” lights, what nm are they, Then to take my question one step further what nanometer range would be best (regardless of if the color is included in your light) to mimic a lunar cycle while as attempting to disturb coral as little as possible during this night out period may cause? Thanks so much!

What hardware are you using to mount those to the tslot? I need to figure out my 63 to get it mounted.

The T track in the meridian body is very shallow and won’t allow for standard 8020 bolts to fit. I ordered the tall bolts direct from reefbreeders and then used my M6 T nuts to thread onto those and slide into the 8020 extrusion.

Tip… I didn’t plan on the lights sliding all over the place and ended up using the flat economy M6 t nuts to tighten the reefbreeders bolts tight into location. This allows the light to slide into the extrusion without sliding both side to side and front to back.

The moon is just reflecting the sun, so it's full spectrum. The light blues are 460 nm

The moon is just reflecting the sun, so it's full spectrum. The light blues are 460 nm

Moonlight has a color temperature of approximately 4100K, which corresponds to a cool, bluish-white light.

This color temperature is cooler than direct sunlight (which is around 5500K–6500K) because moonlight is reflected sunlight, and the Earth's atmosphere plus the surface of the Moon scatter shorter (bluer) wavelengths more strongly at night.

In photography and lighting terms:

• 4100K is often described as neutral white to slightly cool.
• Visually, moonlight may appear more blue than it actually is due to contrast with warmer artificial lights and the low-light environment of night.
• Perceptually (how we see it at night): ~470–500 nm (bluish tint)

Thank you, this is the info I was looking for since I want to do moonlights but want to choose one that is as close to the natural lunar color since I don’t want to introduce spectrums that would more greatly encourage photosynthesis during the night out period

Switched from Radion G4 Pros to the Meridians!! Couldn't be happier

You’re welcome! Based on the data we can see that the 460nm diodes used for moonlight is very close to actual moonlight. And I do recall a earlier post that this was selected to allow viewing while still mimicking night time to the corals

Our cool blue is approximately 465 nm

405–420nm light at extremely low settings is closer to natural underwater moonlight spectra in deep reef environments. It’s less photosynthetically active than 465 and might be better if the goal is the least coral disturbance while still providing a nighttime glow.

For moonlight, we use 465 nanometers for our Cool Blue channel because it’s the best wavelength for simulating moonlight in terms of photosynthetic response. That said, it’s a very bright color compared to something like near-UV in the 390 to 410 nanometer range.

The 390 to 410 nanometer range is also great for moonlight since it’s much dimmer, especially when used sparingly. On the Meridians, we only use two 405 nanometer LEDs, and when they run at low wattage, they generate virtually no measurable PAR, making them a solid moonlight option.

We’ve been wanting to add a feature in the app that lets you assign any channel as a moonlight, but I was quoted ten thousand dollars for that update, so it’s on hold while we focus on higher priority improvements.

There are a lot of features I’d love to bring to the app, but custom app development is incredibly expensive, so I have to be strategic about what gets added and when.

So after running the meridians for 2 full days now after having photons, I have to piggyback onto the others saying moonlight is too bright.

I love the lights, but I have two tanks running 0.1% lunar cycle in the same room. Photons on my 65g and meridians over my 180g. The photons running lunar are perfect. The meridians with lunar cause my fish to be active and the coral is partially opened up. Just my two cents.

We are actively working on lowering moonlight on the meridians.

interesting! 4100K is warmer, but appears Bluer due to the Purkinje effect

Can anyone provide some insight on what settings will work the best for taking photos of my reef with the Meridians? I have an orange phone lens, but I can't seem to get it right, whether I am in the "full daylight" mode or my "Heavy Blue Evening" mode of my light cycle. I have no problem switching into manual for a few minutes to take some pictures. I am looking at you @VintageReefer, but others, please chime in.

Thanks in advance,

Frank

For photos I typically stack an orange and yellow lens (mine connect together),

Orange only

Orange + yellow - better filters out exaggerated blues

I’m using my shared community schedule and it’s noon for me now
