How would you make Ocean revive lights better?

[b4tn]

Now that I have modified my lights so that they can be run from a controller and am comfortable taking them apart. I’m thinking about improving the spectrum. Below is the layout. If you where to move around the LED’s how would you change it and why? What about removing certain colors all together and replacing them with new different color diodes?

I'm not fully versed on them, so bare with me on questions.

What type led diode do they use? 3w like black boxes?

I'll link it.

Doing a little research, they use 3w diode emitters like black boxes.

Using SB reef lights spectrum chart as a reference for spectrum:

And their layout as a guide on k and nm:

And my break down of diodes in spectrum ranges for basic black boxes.


Diode run down per box:

Spectrum / Number needed
20000k 4
14000k 14
3500k 2
660nm 2
520nm 2
490nm 4
450nm 20
420nm 5
395nm 2

You could add some UV with 395nm and 490nm for the carotenoid.

Your layout has 10000 and 12000k's which are close in spectrum, removing the 10000k and replacing with 20000k will open that distance in spectrum.

Why use sb's info as a reference? They are proven boxes with outstanding results.

@dantimdad might be able to chime in on this one.

If it were me I would probably go a totally different direction than most.

Flippers suggestions are solid and proved to grow and color.

IMO, I would replace 4 of the 470s with 410s.

Replace the reds with 4500K the greens with mint. Two of the 10Ks with cyan and the rest of the whites with royal blue.

It may seem very blue but, It really will be toned down to the eye by the mints.

Just my .02

That’s interesting. Have there been any studies showing growth or color using that spectrum?

This was actually my first thought. I never noticed though that the SB lights have 58 bulbs vs the OR 48. I guess I always assumed they where 165w black boxes.

Working on it...

Do you by chance have a thread? I would love to tag along.

Ocean's design is quite different dimensionally than the standard basic generic ebay black boxes.

Over all they perform similar. Aside of timing.....etc. spectrum wise they can vary wildly.

I have been doing everything in my build thread but will start a new one for the light test.

 

[Diamond1]

Tagging along. I would like to see this too.
I'm considering a major overhaul of my t247 fixture to better fit my tanks form factor. Might as well see what can be done with bettering the light spectrum too.

Since we are on the topic of ocean revive's, here's a great write up on diode replacement:

Great info in that link flippers thanks!

What do you all think? Its basically a slightly smaller SBreef light clone. lol LED's are so inexpensive I may just buy all new LED's since these lights are going on 4 years old.

Proposed new layout

Original layout

 

[crusso1993]

I am going to call out to one of my friends for his input. Ok, well, he's not really my friend. I did have a friend once though. Unfortunately, he caused me a little upset and, much to his and his family's chagrin, I had to dispatch with him. Anyway, @dantimdad is light years ahead of most with LED design and layout.

I told you to stop saying we were friends.


Anyhow, I think you are including way too many high temp whites in the mix.

If it were me, and I had to include whites, I would do so sparingly and in a 4500K so it did include some red in it.

Channel 1 seems OK the way you have it. On Channel two I would go with:

6x 420nm
4xmint
2x470nm
2xcyan
4x4500k
6xRB

Now, what this will do is increase the "Visual" brightness and fill in some of the chlorophyll gaps left by channel 1 which will provide most of the energy you need. Also, it would increase the blues to offset the "whites" in the channel so it didn't quickly overpower the blue/violet

I would hazard a guess that you won't turn channel two much up at all in comparison to channel one.

LOL you two.

I really appreciate the input. Just for my sanity check cyan is 505nm, RB is 450nm, What is mint?

Does anyone have a reliable source for the Non PCB LED's? I am not sure I trust the sources I see on ebay.

 

[dantimdad]

You can use the ebay leds. 90% of the black boxes use the same ones and I have been using them for years with no issues. I do get some from Steve's but not unmounted.

495 is cyan. mint is centered around 505 (IIRC I don't have my paper in front of me) but is considered a broad spectrum led not just a narrow peak band.
