nice that made a whole lot of difference with your actinics it became more crisp and less yellow.

yea thats the setup i may just go with and give it a shot. kz fiji purple and uri super actinic blue. read somewhere uri is uvl? or are they different manufacturer?

URI = UVL just depends who you talk to. One call it one way, others call it the other way.

Giesemann's are the worst for it. The Grim Reefer on RC had some photos posted which clearly illiustrated how Giesemann bulbs were the worst for not lighting up the ends of the bulb. I have not been happier since changing away from Giesemann bulbs. I find their bulbs don't hold their spectrum very long either. That's just my experience though.
