Full spectrum lighting question

How does one determine which full spectrum is the best? There are so many variances in colours etc.


If wifi, programming is not considered or required and one doesn't have a specialty tank like breeder or deep how does anyone decide whats the best colour combo etc?

I gave some examples below and would appreciate some opinions

All between 14k and 20k

Light A
12leds
Led Power: 3 watt
LED Brand: Cree: cyan is phillips rebel
Led Colors:
(6) 455nm Royal Blue XP-E
(2) 6500K Cool White XP-G
(2) 405nm UV XP-E
(1) 660nm Deep Red XP-E
(1) 495nm Cyan Rebel
Optics: 60 degree standard

Light B

12, 3watt led

4 Deep Blue 455nm

2 Cool Blue 470nm

2 Neutral White 4500k

2 True Violet 420nm

1 Deep Red 660nm

1 Cyan 495nm

Optics

90 Degree standard

Light C

6 Royal Blue,
2 Neutral White,
2 Cool White,
2 uv
80 degree lenses


Thanks everyone

 

Full Spectrum is a pretty complex way of looking at lights.

The non full spectrum (blue and white) graph would have a spike at the nm for whatever blue and another at the nm for the whites. to get full spectrum you want to be able to cover the entire thing with no spike but obviously lower in some color waves. So in the graphs below A would be blue and whites and B would be more full spectrum.

This is a very brief explanation, i know. The actual spectrum is different with almost all manufacturers, no one really knows what the right answer is. Sorry i could not help more.

 

Thank you, all of the info accumulated is very helpful.

So far I have learned that there really is no full proof with LED, no real standard. With t5 and mh its pretty easy to pick a light.


Led can get really confusing and the 3 lights above all have good reviews from other nano aquarists so choosing the best is hard.

Do you choose the light with red&cyan leds (i've heard red all the time is not good on corals)
Or do you go with the light with no red

Is 14k best or 20k

Maybe I think too much but I am not in a financial situation to waste money plus my tanks livestock is at stake


Dilemma's

 

White diodes are, more or less, full spectrum.

 

read up on kessel brand led lights. it will let you better understand about full spectrum. I went with kessel a360 and love it.

 

I run mine at mostly bottom end 400-450nm...

So you use none of the red?
I'm not a huge fan of how it looks in a tank.

The lights i'm looking into aren't programmable, they are all par38's which a lot of ppl with small tanks recommend.
Kessil will run me well over $400 cda, its not an option

 

Nope just uv and a touch of blue and white. I just run a hydra 26hd which is £250 uk so about 400 ish u.s. Totally worth it, such a good light for a small tank.
