Lighting on an 11" cube + filter an plants Q

I'm currently in the process of setting up an slightly less than 11" nano to trial the tom barr emersed growth method of planting HC and I was wondering what is the best light source once it is set up?
I was considering a single 24watt power compact or possibly a pair of AZOO or arcadia nano lights.
Also while browsing I found a nano LED luminair intended for reefs but this would be spot on, I have emailed the shop and await a reply regarding sutability, the question here really is which method of lighting would people suggest/ say would provide the best source of light?
I would like to avoid co2 injection where possible but I may sway and use diy until funds allow for pressurised if co2 proves to be essential.

For the scape I intend to have a carpet of hc with a center peice of a moss covered unipac root and also some anubias or miniature crypts, something low maintainance anyway, possibly some stems of HM as a back ground.
That or Iwagumi style layout with just HC and moss I don't know ATM, which would people suggest and what plants would you use?
Also I already own a Eden 501 which I intend to use on the tank to provide filtration, I beleive the tank comes in at just over 4.5gallons would this be suitable and provide suitable flow?
Anyway.
Thank you for any responce,
Gareth.

I'm no expert, but I remember reading something about light intensity being more important than watts per gallon, esp for nano tanks. so the single 24 watt CF would be better than 2 13watt bulbs.

If you want to avoid Co2 injection, you could go the low tech rout, or just do a low light setup (but HC won't grow in those conditions). Since your doing HC.. you could also dose with Flourish Excel for your Co2, that's what i'm doing in my 2.5g, but I just planted my HC, so can't say how its doing. People have told me HC tends to respond well to Excel.

Interesting, I'd have assumed the better light spread that the 2x 13watt would be the better source of light which is slightly confusing.
I guess I should have posted the lighting half of this question within the lighting forum and seen what people made to it there.
Is the general concensus that the 24w pc would be better?

I'm still awaiting a reply regarding the LED system but it is daylight spectrum so It should be suitable, I need to do some research on providing power for it thought since im in the uk.

Another question, does anyone know why the redsea pro kit for paintball is only available in the us, is this because uk paintballs use a different thread or pressure or is it simply a geographical issue?

True words, but if mounted diagonally It wouldn't matter.

cheers everyone, I've realised 24 pc really wont be suitable, would 11 watts work or would it be too low light to grow HC well?

Is there anyway you could use a miniaqualight with your tank 18 watts?

Dunno, If they're available in the UK then yes.
The nearest thing I could find was the arcadia arc-pod but they're 11w and in a very odd light colour.
