Reading now. I have been waiting for Sanjay to come out with this article, he has been hinting at it for a while.

Excellent Article - I think it shows that Radion has the right idea. My AI Sol Blue...isnt quite what I thought it was. Whoever can develop a fully controllable LED that mimics a Metal Halide in spectrum will clearly earn market share!!

Just saw this sweet!!!

Makes me feel good about my DIY build I'm about to do.

I don't see much difference between all of them......the Radium has an extra spike in the red range
but they are all similar. I think I just need to add some red to my Sol Blues. Maybe this will help keep
red acans red lol.

I found that quite illuminating! Thanks for the link.

I expected better, yet I'm not surprised either. It sure helps me consider the home made overkill setup though. Looks like a bit of extra Blue is still in order on almost all of them.

Actually red light has been shown to stunt coral growth, try putting the acans in the shade

After reading that link, it makes me want a DIY set up over anything else right now.

Ah crap that's kinda what I was goin to try and put together

So maybe it is just me, but I fail to see how any of Sanjay's article is groundbreaking or news to anyone who has even read anything about LED's.

Sanjay makes some assumptions about Red light benefiting fish and corals with red pigmentation (there is no source cited for this info, or any proof given in the article, so it is his opinion only).

Ok so I've shruged this comment off from a few people ,the red . If red was bad for coral then halide and t5's wouldn't keeps sps ? I'm not a believer maybe he added too much, that's what I think. Also did he give a brand of red led he used? I can't find this thread I would like to see it.

Red is for plant growth and appearance of red corals. There is not much red 30 ft down in the ocean.

Talking about the posts about Red's stunting coral growth?
I think a lot of that stems from rumors and info being propagated through the hobby.
Unless there is a article with experiments proving this, I don't really listen to it.

Now on the other hand, is Red a good color and worth adding? Same thing as above, its yet to be proven.

 

[Wicked Color]

There are studies, I will look for some links.

 

[deadrock]

Sps require more light and they are closer to the surface . Red would be more likely to harm softies and nems.

Attached is the full spectrum of the sun

A couple weeks ago I saw a graph showing what wavelengths were filtered at what depth, red was the first to be filtered, and didnt go much below 3 ft.
Looking for this stuff is like a steering wheel for a belt buckle.

You are correct about that. I was trying to find something about the spectrum at 10m.

Also. Red is the first list absorbed by water. And then it works down the spectrum. Violet penetrates the furthest.

Found it

I know a little about color correcting light filtration for film. Not much different for LEDs.

Green would be the most valuable thing I could see being added for color growth.
