In the recent years the options of lighting the marine aquarium has very much changed. Today there are so many LED lighting or hybrid lighting (T5 pipes + LED). The advantages of LED lights are obvious: Less energy-consumption, longer durability of LEDs and less lost heat as well as a usually very extensive control and setting up options. With selective light sources the curls effect appears very good and „enlivens“ the water optically. Beginners should consider the LED-lighting of well-known manufacturers like Giesemann, EcoTech Marine Radion, Maxspect, ATI or Tropic Marine.
