Had me some time ago a used gem gained 190 Eckaquarium. Now the exchange of T5 lighting was needed. In stores here locally taste the good pieces of other brands well 25 - 30.- pcs. What I was much too expensive for a "neon". Here at Amazon I found the T5 tube of jewel. Good, uniform light output (without reflectors), at an acceptable price / performance ratio, good, 28 watts is at the present time, a relatively high consumption, but then you have to switch to LED. I am satisfied so far.
