Workhorse Config Recommendations
 

Hey everyone.

I'd like to OD my two 4' URI NO actinics and was wondering what people think would be the best way to go.

The 2 lamps in series with Workhorse 5, all leads to one bulb?
The 2 lamps in series with Workhorse 7, all leads to one bulb?
The 2 lamps in parallel with Workhorse 5 or 7, 2 leads to each bulb?

Is it worth OD'ing actinics (or any bulbs) more than 2X?

With the URI's and my two 175w 10,000K Hamiltons the tank is on the purple side. Anyone try the Zoomed T8 actinics - any bluer?

TIA
Ron
