Regarding the Poco system, a Virtual Circuit refers to an actual physical hard-wired circuit containing two or more Lumitec light families that will retain the ability for the light families on the same physical circuit to receive separate commands from the Poco module and behave differently. This is due to the “Smart Light” PLI technology built into the light that will receive all the commands sent from the Poco module but only react to the commands directed to that specific family. This means you can have multiple light families on the same circuit/channel as long as you do not exceed the max amp limit of 10 amps per channel. Thus, the lighting for the vessel can be spread over all four channels for a max load of 40 amps.
