T5 Important NOTE

Modern T5 technology is a very good and cost-effective
alternative to LED lighting. Giesemann T5 fluorescent tubes
are available in a wide variety of lengths, light colours and wattages.

Contrary to some claims in the market, there is no European-ban on T-5 lamps for biological purposes, i.e. in particular for lighting aquariums and terrariums.

Such a European ban is also not planned for the future, so that the use of T-5 lamps for aquariums and terrariums is guaranteed for years.

In many areas, T-5 lamps offer many advantages over pure LED lighting and especially in combination with LED light sources (hybrid systems), coloured T-5 lamps convince with their benefits.

GIESEMANN Powerchrome T-5 lamps are manufactured exclusively in Germany and offer: Excellent colour rendering, light colours and colour combinations that can only be

achieved with T-5 technology, a long lifetime and colour stability of over 10,000 hours, low maintenance costs and high light output per Watt.

T-5 lighting is still the most cost-effective way to illuminate your aquarium – no matter if it´s a reef tank or a sophisticated freshwater tank.

At Giesemann we stock T-5 lamps in all popular light colours for freshwater and marine aquariums and offer you a selected range of different lighting systems for T-5 lamps, including hybrid systems.
