LED lighting system to buy:help!

[marcoitareef]

Hello!
I'm italian (and I hope I will not make any write error), and I'm 23.

 

First of all, I have to say that I never had saltwater tanks. I have 6 years "freshwater tanks" experience, with ADA setups, aquascaping, high tech tanks.

 

Now I want to start my first reef tank.

I'm reading guides about reef tanks setups, making of.

Honestly I don't know very much about corals needs, I have no experience in that.

I can say that I already decided to insert some Zoanthus, some Ricordea, Euphyllia, which I learnt are not very difficult. Maybe even something more difficult (maybe even SPS, I like acropora e.g.).

At the same time, I don't want to be "too much restricted" with lighting because increasing my experience I know that I will try more difficult corals (as it was with freshwater tank plants).

 

So, I'm writing too much.

Let's get straight to the problem:

I have to use a 80x40x50 (centimeters, or better I think around 31" x 16" x 20") "only glass" tank, it's 40 gallons (maybe too big to call it nanoreef?)

 

I was thinking to use LED. I have HQI on freshwater, but I want to use LED this time.

Someone talked me about Maxspect Razor 160W. But 160W are too muchexpensive for electrical consumption. I have 150W HQI but with leds I would like to reduce it.

So there's Maxspect Razor 120W.

 

Do you think that using Razor 120W, I would be too much "limited", restricted (don't know how to say, hope you understand) on coral selection? Of course 160W would be better, but 120W Razor is good enough to have even something more difficult (maybe not "highest" difficulty but almost something not too much easy) or 120W are too few?
maybe the razor 120W it's too smal (28" lenght) to have a good coverage?

Maybe TWO Maxspect Razor Nano 60W together, would be better?

 

Or what do you suggest me to have good light? (remember that I'm italian, we are not a great country, unfortunately things like this often costs more (for example iphone starts from 729 euros (it's 1000$), but in other european countries it costs less, and in US it's 729$ which are 540 euros. So you know what I mean...) and often aquarium products, that you have in your country, aren't here in mine...

Thank you, sorry for the lenght of the post.

Hope you answer!

Being 31" long, the 20" R420R (which actually has the LED pucks spreading out ~12") might have issues on the far ends of your tank. If you're not planning on keeping any corals on the ends, it will be ok, but the edges will be noticeably dim and that may be irritating. If you get the 27" R420R, you do not need to run it at full bore. Most people end up maxing out around 60% or so.

 

I would also consider purchasing the wide reflectors. They reduce the 'disco effect' and will spread the light out even more, which is better for corals.

I'm sorry that I waisted your time (even my time, writing all this stuff for a thing that I could think myself ). I will buy the 160W version, because as user @JDH told me, if I'm not doing full SPS, I will not max out the lighting system.

And customization is exactly why I want to use led.

(I was writing this and I didn't notice the answer)

 

I was very stupid even asking

 

I will go with the 160W version!

 

Thank you @jedimasterben
