has anyone use this bulbs? "250 watt 20K Helios DE"

how do they compare to Phoenix 14k on an electronic ballast?

also has anyone used the Hamilton 14k?

I'd like to know as well.
I'm looking to test out the 20k helios but haven't seen much reviews or pics.
I've heard the 20k helios 250w SE are pretty nice and compares really close to the 250w SE radiums.
