Im using an profilux plus 2 for 4years now and im really happy about it

But im building an new aquarium right now and i want to think abou the possibilities of led lights

So i found the ledcontrol4 box...

Ive seen the passive and the active
What are the differences of those two

Now i want to know if its possible to use these leds

On the ledcontrol4

and is it possible to shut them down to 0% with the profilux or do you need time switches to do that

And how many bars can you connect.
Is it possible to only use l1 and l2 for only two led bars instead of four

Hope to hear soon
