It might help if you would tell us what leds you have now?
And are you looking for color pop in the lighting itself, or color pop in the corals?
If it's the corals, do you mean daylight 'normal' reflected color or bluelight fluorescence color?
If you have a good led fixture, even most Chinese' boxes, you should get all the color pop you could want. I think people add t5 to their leds for better coverage and to reduce shadows under ledges and coral plates.
