Hi Wayner,
Yes, we did several test with the 20K's on standard and hqi ballasts. Definately want to stick with the hqi ballasts on those bulbs.
It was a surprise that the 250watt 20K did look different then the 400watt 20K. The 250 20K was much more blue. It still looks nice, but the 400watt 20K really had a better look color wise to me, but that's subjective to the eye. I think the 400watt is just able to push out the white spectrum a little more and still have the nice blue cast.
I was also surprised to see how nice the 12K looks on a 400watt standard ballast. It runs pretty dim on lower wattage ballasts, but the 400watt 12K standard looks pretty close to a 20K 400 hqi setup. The 20K certainly is better, but for a budget, the 12K looked really close.

Hi Nilson,
<<Understood that the 20K runs better under HQI ballast, what about blueline.
When we compared PFO standard to PFO hqi was night and day difference. Haven't had a chance to compare on Eballast yet.
<<By the way, do you have any 220 volts 400W HQI ballast.
PFO can make there standard or hqi ballast into 220volt. Drawback is the weight though, probably around 20 plus pounds, so would be expensive to ship to HK.

hi Chris,
Sorry, haven't tried it on icecap yet, i'll put that on the to do list. The new Icecap 250 claims it will run any bulb, except 65K, they have a special one for that. So it should drive the bulb, Icecap can special tune for hqi bulbs as well though, so imagine a special tuned ballast for hqi would work really well.
