Profilux P4 The New Flagship Controller from GHL



It was recently announced at MACNA 2016 in San Diego that GHL, the makers of the Profilux controller line, dosing pumps and Mitras LED fixtures will be launching a new aquarium controller dubbed the P4.

The above photo was taken at MACNA and as you can see, GHL will be offering the P4 in two color choices.  The very attractive P4 controller also offers many upgrades that the current model lacks and Vinny Altamirano from GHL USA was kind enough to put together some details for us (see below).  The P4 controller is expected to launch later this Fall.  Pricing on the controller hasn’t been set yet but GHL should be releasing that information ahead of the anticipated November release date.
