Lighting upgrade?

[Tayari]

I am currently using a current Nova extreme 8 X 54W fixture over my tank. I have been thinking about switching it out for a Maxspect razor 300w led unit. My question being, would you consider this an upgrade to my existing light? I don't want to spend that kind of money for an led system only to have less light. I am happy with the features offered with the maxspect as well as the type of leds used in it, but I haven't been able to see one in action.
