This the same ballast they are calling HQI for 400 watt?

I believe so Jeff. PFO 400 hqi ballasts are really HPS 430 ballasts

Ok Sean thats what I thought.. Might buy one of these and run one next to my CV eballasts and see what I think...

[moonpod]

yeah, that's the "socalled" 400w hqi.

Moon, is the taiwanese a different HQI?

[Diesel3443]

Jeff, I dont know what the real diff is Moon will have to answer that. But according to Sanjay's testing the taiwanese didnt give as good of numbers with a lot of the bulbs I researched

Sean, thanks for the heads up... Looking at PA now to get the dual 400 SLS HQI... Same 5 yr warranty I would bet anything they are the same internals as the DIY posted above...

The Taiwanese "HQI" is putatively a real MH ballast unlike the sonagro 430w HPS. Again, there are ALWAYS individual bulb/ballast combo relationships and some bulbs will like the HPS and some will like the Taiwanese. The general belief however is that ultimately, the HPS will "punish" the bulb and life will be shortened appreciably with early color shifting +/- fading output and out and out bulb death. Not enough experience with the Taiwanese "HQI", but presumably it's more like the 400w "euroballast" seen on say a Giesemann 400w fixture. Bulbs should last "normal" lives on them, but who knows.
