The TMC AquaRay MultiControl 8 LED lighting controller unit has eight sockets with dimming control and timers and runs all lamps plugged into it from a single mains socket. 

The AquaRay MultiControl 8 features a "simple" interface which lets you create sunrise, daylight and moonlight lighting phases for your aquarium.

The AquaRay MultiControl is suitable for eight AquaBeam or GroBeam 500s, four AquaBeam or GroBeam 1000s, or four AquaBeam 1500 XGs, or any combination.

The lighting controller has two independently timed channels, with six outputs timed separately from the other two.

Internal battery - settings remain after power failure.

Just one plug to power up to 8 Aquabeams.

There's also a built-in "storm function" which TMC believe could encourage breeding in certain species.
