E5 blue pop

[Delphinus]

I've been kind of wondering about these so thanks for the review. In particular these "blue pop" since they're claimed to be at 450nm which makes me think they're similar to the old 454 t5's we used to be able to get (I would run 454 plus actinics for my dusk and dawn).

I'm not sure I understand though why you decided to go with fewer in the end? Are they just too bright otherwise? In the first picture where it says "third from left" is it actually on? (Because it looks darker than the t5's)

Thanks!
