Hi Vinny,
thank you for the feedback.
4x LX7004 would certainly look better for us as they are smaller and make a smaller footprint... however I want to make sure I understand correrctly that this would still be sufficient lighting for a CO2 supported planted tank? When I look at the product specs it says for LX7004 it is sufficient for max 160L... 4x LX7004 would then be for 640L tank?? LX7006 says it is for max 240L so 4x LX7006 would be sufficient for 960L tank?

Our tank will be 1100 Liters, so - just to confirm: would in your opinion 4x LX7004 still be sufficient for this volume?

I intend to have discus fish and 27C temperature so it will be rather limited as to the choice of plants and their environment, but I still want to give them as good support for growth as possible.

Thank you!!
