Eheim added T5’s to their lineup, the marinepower and freshpower. The marinepower T5’s are available as an actinic blue and hybrid. The actinic blue takes care of the 400-480nm range, while the hybrid is a blend of daylight and deep blue spectrum. They compliment each other nicely, and should give reefkeepers another option in bulb choice.
The freshpower line includes a daylight spectrum and a plant specific tube. The daylight tubes are self explanatory, but the plant bulbs are designed to emphasize the red and blue spectrum. While they are badged freshpower, both the daylight and plant bulbs could clearly serve a purpose on the marine end as well. The bulbs are made right here in Germany.
