Lumenbrights or lumenmax

[jlaudiofreak]

I have a 30" wide tank buy 24" deep. What would give me a better spread across the 30" . Lumenbright large or lumenmax large. I already have 4 lrage Lumenrbights over the tank now, just want to see if I would get a better coverage switching to the lumenmax large
