I want to connect 3x Mitras Lightbar Daylight 160 to my tank. I currently have 2 already with 200w power supply, and 1 splitter.

I have 3 options if i am correct;

1) Upgrade my current power supply to support 300w; then i can connect 3 lamps (=3x 96w)

2) Use the GHL Mitras-Lightbar-ProfiLux-ActiveSplitter
This seems to be only needed if i want to connect more lamps to 1 splitter than the PSU can handle. E.g. if i want to add 4x lamps 160cm, which equals a required 400w power supply.

3) Use a PLM-RS232 + PL-1051 (interface cable) + PL-1048 (splitter) to create a second Serial port.
I am not sure if this will work together with the first serial port also in use for the Profilux.

Please advise.

Gilles
