Mitras Lightbar 3: Beautiful Light and High Performance
I would like to thank you once again for the great Mitras Lightbar 3 lamps. They provide a very beautiful and uniform light. A check with a light meter has shown that the lamps perform significantly better with the same power consumption as the previous ones.
That’s why I’ve dropped the original plan to use combination lighting for the new tank and only want to work with the MLB 3 lamps.
