Cyan, Red, Green and UV LED

[dlogfx]

Just wanted to find out if anyone is using these colors in their DIY fixtures. I'm think of adding some color LED but don't know if it's even worth it to go through the trouble.

Color is def worth is but can't speak for bridgelux as I have Crees.

I have heard that all colors are beneficial and would make a good addition

I have them on my tank 6 Red 6 Green without optics and like the look on my 330 gal SPS

I consider them the spice...too much will not look good

So as I look to my own DIY LED fixture....how do you decide how much of anything other then white, and how do you pick the placement?

I would look at Royal Blue (450nm) as your primary LED. The Cree Cool White Grows coral because it has a very nice 450nm spike.

Depending on Bins a 2:1 Royal Blue Cool White Ratio is 17-20K 1:1 is 10-12K

Placement is just evenly mixing them on the heatsink If you choose to add Reds and Greens skip the optics.

So if I am reading this right...you just plan on 2 blue for every 1 white, then evenly space out colors if you decide to do colors?

Yes

The 2:1 is the grow.

Everything else is the spice. I know its simple and will get some feed back. But this is proven to grow coral.

Bill, what's your take on the new UV type LEDs?

I have 30 of 410nm SemiLED P2N-U on my 330 Gal SPS tank and really like the look.

The only downside is they are not as bright as the Cree XT-E and they are more expensive.

Personally I wouldn't consider a 410nm a UV. It is Violet. To get an actaul UV you need to drop down below 400nm... I know it is considered UV by just about everyone but me. lol

I have 6 Green(520-525nm), 6 Red(620-630nm), 6 Violet(3 410-420nm and 3 420-425nm) , 4 moon(which is just a dimmer Royal Blue), 26 Royal Blue(450-465nm), and 26 Cool Whites on over my 55. The whites are only at 50%. I plan on using 3 of these over my 180.

I am also going to add two more fixtures with secondary lights. I am going WAY overboard but I want to have a full spectrum. On the seconday fixtures I am going to have 6 each of Deep Red(650-670nm), Turquoise(500-600nm), UV(365-375nm), Cyan(490-525nm), Red/Orange(610-620nm), Blue(465-485nm), Blue(440-450nm), and Amber(585-595nm).

Wish me luck!! :tongue:

UV is just the shorter way of saying violet when it comes to LEDs. Really only a couple reds, red-oranges, blues, and greens are needed. Violets can be added in mass quantities with no problems, as they hit the chloryphyll a peak on the head.

So how many of the red/green/uv do you need? only line 1 or 2 each? (looking at a 55+ tank)

 

[Soehl]

As far as need goes I don't know... lol I put 6 of each on their own driver and then limit the time they are on daily. I want to simulate the peak hours where the sun would be highest in the sky so I leave mine on for just a couple hours daily. My current tank is a 3' 55 gallon and if I were to go with a minimum set-up I would probably run them together and have 2-3 of each on the same driver. Although it is kind of hard to mix LED on the same line since they require different amps per.

So I ended up adding 1 cyan and 2 UV LEDs to my build. I'm really liking the results as far color goes. Time will have to tell if it helps with growth.
These are the LEDs I have on the fixtures:
1 neutral white
2 cool white
3 royal blue
1 blue
1 cyan
2 UV

Here are some pictures I took really quick with my phone.

Its personal preference...Ginger vs Mary Ann...Who is better looking...

For a tank your size 3-4 Green and Red without optics will have no negative feed back when run with the High Noon LEDs. If you can put them on a dimmable driver so you can tweak the colour perfectly.

The UV/Violet is dimmer than the XT-E Royal Blue, to make a difference at least 8.
