AI Prime Vs Arcadia Classica OTL

[Twisted Melon]

Hello peeps.

So I’ve been choosing lights for about a month now. Getting bored!

Decided not to go for the Kessils and decided against a custom built light in the end. So......

Any opinions on these 2 lights for my setup.

3 x AI Prime FW

Or

1 x Arcadia Classica OTL 1200mm.

My tank is - 137cm x 46cm x 46cm
(54”x18”x18”)

Thanks muchly!!

Oh, and is 1 Arcadia enough?

Thanks

Also, I can see that AI have 2 lunchtime goosenecks. 18” and 12”.

How do you know which you need?

Thanks again.
