Max 10 to 15ma per socket according to this linkhttp://forum.aquariumcomputer.com/showthread.php?L-port-current
Then also consider that you should calculate a 10 times current draw for inrush current draw on initial start.
Definitely a no go.

You could look at some of the lighting control modules which have switching which is activated from the L port. But have not used or played with these so can't offer any solutions there really, except to have a look yourself.

Or if you are really serious and know your electronics you could build your own relay system which is activated from the L port. You would need to get more data from Profilux on this as you would need to know how the L port is activating a switching signal and then build the module using a programmable chip and maybe some software.

Of course the cost and time of doing this, it would probably be easier to buy another power bar!
