Which LED length fits my aquarium?
You will find a tabular overview on the packaging of every LED. This will tell you which LED SOLAR fits your aquarium. There are two application scenarios for this.
1. You replace an existing T5/T8 tube to install the LED as a retrofit. In this case please refer to the relevant column. Most aquarium owners prefer the shorter model because of the small distances left and right of the tube socket in the aquarium cover. You can either select according to the length of the tube (in mm) or according to the wattage.
2. The second type of installation is as a top assembly or hanging installation. Here the maximum aquarium width is decisive. Please refer to the relevant column. For this type of installation, always choose the larger of the two options for optimal illumination.
