Helios 400W 20K bulb review/opinions

[Unarce]

Hi everyone!

I was not able to find much info on this bulb through a Google and RC search. I've heard that it's readily available in SoCal, and thought perhaps I could get a review, or better yet, some sample pics of it in action.

Right now, I'm using the 400W Radium/PFO HQI ballast combo, and would like to get in a little more blue without sacrificing much PAR. According to Sanjay's test/plot, this bulb puts out more blue than the Radium, when coupled with the PFO HQI ballast.

At this point, any info on the bulb would be great

Thanks!

A friend burned them with a Dual 400w Blue wave ballast, it looked pretty dim. I burn mine with a 400w E ballast,it's very bright but it isn't bluer than the radium or Xm 20000k at all. If you want it looks bluer I guess you should look for the ballasts give the least pars.

Thanks, Loc!

That's what I've been hearing. I may give the XM20K a shot.
