Reef Breeders and Reef Radiance

If any vendors or manufacturers are looking for input, what I want is a dimmable fixture that is apex controllable and does not include its own controller. I see no point in paying for something I already have and have been waiting for someone to come up with one in the same class as the evergrow stuff.

That is a common request, and we are working on a solution for that. We should have something ready after the supernova is released.
 
i recieved my 3 reef radiance leds yesterday and man was i impressed im glad i went with theses light Rick thank you again for such awesome service

HI Glamisracers - thanks a lot for the feedback. I never get tired of hearing from happy customers. We work very hard at Reef Radiance - really hard - to source and provide the very best LEDs available at prices that allow you the extra cash to buy the other stuff you need for you aquarium. Every member of our team is a Hobbyist and we all get a kick out of letters like yours. If you have pictures - send em over and we will post them on our site. And for sure - put them up here so others can see how they look over your tank..

Keep Reefing!

Rick
 
Please stop saying UV, please just say violet or hyper violet (428nm peak), saying UV when referring to violet leds creates a ton of confusion in that area.

I agree UV is 325nm or 365nm, and yes there is an led at this wavelength. I have tried these on my coral, not for growth but for color and it does not add anything to the colors.

It's funny how so many of the led fixture manufacturers are adding the 400-420nm leds (sometimes lots of them), calling them UV and telling the buyers how much they help with the colors of the coral. It's not UV, it's violrt and the corals use it pretty much just like most other shades of blue leds, but I think the 440-480nm range is more important.

it's not so much the color of the coral that the violet LEDs enhance, it's the fluorescence in the coral, kinda like a black light does for the cool black light posters of years ago, the violet LEDs do a better job than just the blue LEDs do in adding that glow, to my knowledge though, that is the only real benefit of having the violet LEDs, but I am still very new at LEDs :)

That is what I was trying to say, I used a 365nm uv(Ultra violet) led black light and it did nothing to help the fluorescence of the color, it actually kinda washed them out. I was not impressed.

Read up on coral pigments. It isn't the reflected light that makes corals fluoresecence light ( and reflected light is how we see most colors). Coral pigments make and emit their own light and they don't use UV or even violet to do it. Almost all the pigments that emit light (there are something like 10-15 of them I think), do it by taking in 440nm-480nm blue, use some of the energy and then emit light with less energy (green, yellow, red, etc.). It has nothing to do with UV or even 400nm-420nm violet spectrum. If you want to learn, let me know and I'll find an article or 2 on the subject. I'd do it but I have to run off to work!

IIRC there's a big spike in Chlorophil a at 410nm and an even bigger one at 428nm, and one at 660nm-680nm, it kinda drops down at 445nm-455nm, but all the others seem to have large spikes around 445nm-495nm

I'd like to see the info for the "big spike in Chlorophyl at 410nm". I'm not saying you are wrong, I'm trying to learn and I have never seen info to support that statement. Zooxanthellae use Chlorophyl a & c, and the graphs of what spectrum they use (that I have seen) show some 400nm to 420nm use, but not what I would describe as a 'spike'. It's more of a gradual increase up to peak at about 450nm and then falls off sharply by about 475nm. Yes there is some use of red in Chlorophyl. But then Chlorophyl isn't what makes the fluorescent colors we see in coral. It's what runs the photosynthesis and feeds the zooxanthellae that feed the coral. If anything, to much zooxanthellae makes corals look brown.

And by the way, I'm willing to admit that I am pushing the limits of my knowledge in this subject. Like I said, I'm trying to learn too.
 
I can't remember where i got the info from, I think it was a thread on NR, I'll try to find it!
A lot of the "spikes" I was talking about were most likely gradual increases.
Everyone is trying to lear, all the time :)

The peak is all but gone by 450nm for chlorophyll a. Chlorophyll c is only 10% of the chlorophyll in corals,a is the other 90. Check this graph out:
