Which Lightning for my new 20L Tank?

[eoto]

Hello,

i am searching after a Light for my new 20L Tank that i will set up soon.

Facts:

20.6L Mini M (36x22x26cm)
Will be an Iwagumi
The Light should look good as im using only Glasware on the Tank.

So i know there are a 2 out there that would fit my Aquarium but please feel free to show me more Lightings i could use on my Tank.

Aquatic Nature Solar Duo Boy 26W 6500K White or 7100 - 6500K Red/White

Aquatic Nature Spectra 18W 6500K White or 8000 - 7100K Red/White

Which one would you prefer? And why?

Cheers from Germany and sorry for the bad English,
Florian
