The one at the front is Tiger and at the rear is Red, strangely enough the new leaves of both have grown with pretty similar colouration under this light whereas they were easy to identify before.Is that C. spiralis Red or Tiger?
I intended to say above that I'm definitely getting better growth down at the substrate level probably due to a better spread of light as opposed to the point source but I also think the addition of UVA is benefiting all the plants, all new leaves are slightly different than before.
