I ordered two lights for my 100 × 40 × 50cm Aquarium. The shipping was faster than expected. Super packed, super quality, I find there is absolutely nothing to complain about. Especially the touch sensor is great, a light touch is enough, you can select the three lighting options. Two lights are for my little aquarium too much, because I think Axolotl and these are very light sensitive. Through many plants my light is slightly dampened. A lamp 1m aquarium rich in my opinion completely. As an alternative to the far too costly seawater Lighting absolutely perfect.
