Lumens vs. CRI?
I'm trying to decide between two T8 fluorescent lamps for a double
fixture over two dwarf cichlid tanks (20L) which will also contain
dwarf species of swords...
Initial Lumens: 1300
Mean Lumens: 1160*
Initial Lumens: 910
Design Lumens: 850
All specifications and other factors are basically the same except
the lumens and CRI. I like the lumens of Lamp 1, but the CRI of Lamp
2. Comments? Which would be a better choice? I feel the light in
either case is adequate for the tanks. Since the fish are Rams, I
like the higher CRI to enhance their colors. Would it make sense to
use one of each in the double fixture?
