Opinions on 20K SE metal halide bulbs

I did color com parson shots of all there 250 watt bulbs, I found the 20K one lacking in PAR and almost no difference in look from there 14, which had decent PAR output. I was using there bulbs as I had a deal with the owner but he reneged on our deal and disappeared, so while there bulbs are a cost effective bulb I find the company its self rather unscrupulous and I cannot recommend them to anyone anymore.

Thanks for the great information. From what I've just read, it would seem that the Radium 20K's would be a better option that going with the XM's or the Sun Aquatics due to the fact that my ballast is HQI.

Why not give the EVC 14k's a try? They are actually much closer to a 20K bulb yet yield more PAR.
