Thanks guys but I went with 2 pure actinic ati bulbs. I run 4 10000k 2 blue plus and 2 Fiji purples in the day and wanted to try something really actinic and see what it would produce. I do like the blue plus a lot but I wanted to try something a little more actinic per say. But I will update this thread in a few days when I recieve them and let you know what I think about them and yes I have a 12 39w bulb t5 light and just use ati bulbs
