Reef tank lightening developed a lot in the recent years, so a wide collection of lighting options are today available to the marine aquarist. Over the years HQI and T5-piping system are proven systems and so usually the first choice for the beginners. The costs of a T5 lighting system are not so high, however the current power consumption of a marine aquarium is higher.
Modern LED lighting of manufacturers like ATI, EcoTech Marine, Maxspect or Giesemann are commercially very interesting and offer a lot of setting options. We would be glad to advice you!
