My spectrum

[senne76]

Hello,

I'm building a led ficture and calculated my spectrum.
I'm using luxeon es leds from stevesleds.
This is an idea (my second idea):

The yellow ones are neutral whites and I think that you know what the rest are.
The spectrum :

But they told me this is to white so I made this design:

with this spectrum:

What do you think , is one of these good?
Oh yeah , they can be dimmed by colour

I'm not up on StevesLEDs and don't know what your shooting for so I'm just guessing. Try this and see what the spectrum spread looks like...

5 Royal Blue
4 Violet
2 Warm White
2 Cool White

I think the WW will meet the requirements toward the upper end of the spectrum (red) and the cool whites will help with the lower end (blue/cyan). I'm assuming you're setting up for corals so heavy RB and V is good. Remember the green, yellow, and orange part of the spectrum don't help much other than color rendition.

This is the resulting spectrum from your set-up:

Here are the led colours:
Purple: Uv : http://shop.stevesleds.com/3-Watt-True-Violet-LED-TrueViolet.htm
Light blue : Cool blue : http://shop.stevesleds.com/Philips-Luxeon-ES-True-Cool-BLUE-3-Watt-LEDs-Luxeon-ES-cool-blue.htm
Dark blue : Royal blue : http://shop.stevesleds.com/Philips-Luxeon-ES-ROYAL-BLUE-3-Watt-LEDs-Philips-royal-blue.htm
Yellow : neutral white : http://shop.stevesleds.com/Philips-...3-Watt-LEDs-5000K-Luxeon-ES-Neutral-White.htm
Red: Deep red: http://shop.stevesleds.com/Philips-Luxeon-ES-Deep-Red-3-Watt-LEDs-Luxeon-ES-Deep-Red.htm
Cyan: cyan : http://shop.stevesleds.com/Philips-Luxeon-ES-Cyan-3-Watt-LEDs-Luxeon-ES-Cyan.htm

Ok. Now I have a baseline... little different than Crees. I'd stick w/ your last set-up. Too bad there's not some way to boost the violet peak without sacrificing blue, cyan, or red. Could you just add two more violets or are you limited to 13?

 

[YoungREEFA]

well, just go 4 royal blue, 1 440nm blue, 1 red and 2 neutrel white, 2 ww and 3 violet

 

[senne76]

I can't find 440nm blue but the royal blue are 440-450nm ?

 

[senne76]

What do you think of this weird design? I added an green led and a royal blue led:

 

[reefgeezer]

I'd change the cyan and the green out for two violets.

 

[YoungREEFA]

yeah no need for green in limited space, go violets, and the royal blue will be just fine

2:3 ratio of NW:RB or 1:2
with 15 i'd do
6 RB
3 NW
1 DR
2 TV
1 cyan
2 CB

Isn't that too blue ? I like more like a 10000k look with all the leds at 100% , and in the evening I dim the whites to get blue light. The blue leds are really powerful in comparison to the whites
The 13up module of nanobox also uses a 1:1 ratio?
This picture I got from stevesleds and it shows 10000k light and I like the colour:
