i am looking at upgrading my lights and i want to know what the pros and cons are of magnetic and electronic ballasts are. also what ballasts have people had more pleasant experiences with. i was thinking pfo hqi ballast with 20k helios bulbs or ushio or radium bulbs. or perhaps ice cap ballast with those bulbs. these will be 400 watt bulbs

the pros for a electronic ballast is that it will fire up any kind of bulb.
I personally use HQI and really like the PFO ballast. The bulbs you chose will work good with an HQI ballast if you use other bulbs like i use the XM 20K with HQI, the HQI ballast will overdrive this particular bulb and it will not last as long as it would on a Magnetic or electronic but the color is so much better the HQI takes alot of the blue out and makes it more white, which i like
I would go with the pfo hqi and radiums in lumIII's
You can see the dif between 250/w 15k and 400w 20k in the pics in middle of page
I now have changed out the galaxy e ballast to HQI
