sera X-Change Cool Daylight 520 LED tube.

The new sera LED X-Change System allows easy conversion from fluorescent lamps to modern low-voltage LED aquarium lighting. Energy cost savings, excellent light quality and long life are not the only arguments for an environmentally friendly light source; the sera LED X-Change System even allows you to change lighting scenarios in an uncomplicated way. Combined with the sera LED Digital Dimmer, the light can be slowly dimmed up and down in brightness.

SERA LED X-Change Tubes can be installed in the existing fixtures of a previously used fluorescent tube using a separately available adapter for T5 or T8. The T5 or T8 fixtures are disconnected for this purpose and only serve to hold the tube in place. Power is supplied by a low-voltage cable and a 20 V ballast (ballast not included). Several sera LED X-Change tubes can be connected together using the sera LED Triple Cable and a ballast (watch the total current!). Of course, it is also possible to install waterproof sera LED X-Change Tubes individually.

-Blue daylight tube for all freshwater and marine aquariums.
-10000 to 12000 K depending on the dimming state.
