The Sera X-Change daylight tube creates natural and true-to-life daylight colors. It represents tropical light with a color rendering index of about 90, similar to natural sunlight, making it suitable as LED lighting for all freshwater aquariums. The bright LED illuminates the aquarium perfectly without altering the natural colors.

The combination with the digital dimmer from Sera allows for adjusting the brightness or light intensity of the Sera X-Change daylight tube. It is also possible to simulate sunrise and sunset at individually programmable times.
