Adding extra LED module to Marineland- advice

[Shelby2012]

I have 24" Marineland Reef Capable LEDs and after adding a few corals to the tank I decided that the placement of the corals is pretty limited so I would like to add more PARs to the existing lights. I was looking at some strips but as I understand they do not add PARs to the system. They are just for our viewing pleasure. Could you recommend anything for up to $100. Preferably something that will not take too much space. It would be great if it has more blue spectrum. I know I could build my own so maybe some easy kit?
thanks!
