No white light

[Lasse]

so what is the trick? Just turn on RGB?

This is the matrix - as you can see - its a lot of blue and a 1 red, 3 orange and 1 green - the rest consist of different blue wavelengths

Every matrix consist of 20 LED. My lamp has 6 of these matrix. Total 120 LED. Cyan 18 pcs, Amber 18 pcs, UV-A 18 pcs, Moon 6 pcs, Blue 1 18 pcs, Blue 2 18 pcs , blue 3 12 pcs, red 6 pcs and green 6 pcs. Cyan is something between blue and green but there is total 90 LED belonging to the blue wavelengths, 18 amber, 6 green and 6 red. This mix create the white looking of my aquarium.

Amazing what a awesome tank!

Look superb!

Thank you both

Just watched the Jason fox video, very interesting. He runs his hydras with 5% red, green and whites and max all the blues, but his lights are about 2ft above the water

Very interesting!

No need for white lights. Go with whatever looks good to you.

Jason Fox uses "blue actinic" T5 and Reefbrite LED. I'm assuming he's referring to the Giesemann Actinic Blue bulb (ATI Blue+), but he didn't state that explicitly.


Somewhere in there he mentioned his LED tank only has red/green/white for a few hours at low %.

Thank you for this, if theres one set up I wanna hear about its this one! Im giving the more actinic T5s a shot when I get off work.

Do you think Jason meant Blue+ or straight up actinic T5s?

Very interesting. I put my hydra 52 hd on my 60 3 months ago i started out at 0% red and greens with a 10% cw. My corals looked nice glowed all over the place. Since then i have raised my specs on my red green and cw. Not sure if it really helps but the corals look nice. I have always wondered about my lighting schedule. Everyone seems to run their lights in different times.

You can have this without any white LEDs - just use the RGB trick. It means Red, Green and Blue. Look at the Pictures from my tank - no White LEDs there

When you put RBG all next to each other they look white. And is white really white or is its a percentage of RBGY in their own spectrums....

 

[PopaSmurph]

I run blue+ and purple+ t5 and those look pretty white for the day time untill my actinic and blue pops kick on. So i dont run any white bulbs but i get a white look from the spectrum i produce. So you dont need any white leds those are just wasted spots. the matrix has alot going for if your into leds.

Your brain is tricked. White light - per definition – contains a mix of all the wavelengths of the visible spectrum at equal intensity.

But in some way the eyes reception molecules translate monochrome red, blue and green wavelengths mixed together as white light and your brain report to you – this is white

When I first heard his presentation I took it to mean true actinic, but that's because I was only thinking of ATI bulbs. Later after thinking about it and re-watching the segment I believe he means Giesemann Actinic Blue (or ATI Blue Plus).

This two Pictures are taken 10 minutes ago. No White LEds. No photoshoping. it looks like this!

Why does it look so white then? What light are you using

 

[Reefertanks]

All blues from sb reef lights and kessil a360TB 12 hours a day with Uv no whites in over a year.

 

[Tommy's Reef]

No whites ever lol. Been that way for the last 3 years

 

[chefjpaul]

I just cut mine after adding t5's to my leds

I use Pacific Sun Metis Hyperion S 3*145 W.

I rarely run white with a black box and corals grow healthy and rapid.

 

[Donovan Joannes]

Cyan, turquoise and teal colored LED creates a nice (almost like) MH looking white light when combined with other color.

The thing that you guys are missing on this is that there are two different color scales.

So let's say your mixing paint using the standard color wheel we all learned about as kids. Red, blue and yellow creates black in the perfect mixture. Red and blue together make purple. Etc. This is called "subtractive color mixing"

Light sources work off of "additive color mixing" and it has the opposite effect of th subtractive color wheel. So RGB light sources combined creates white. It's not a trick though. The actual color that's created is white and it is the same white that a white LED would create.
