Helios 20k 150w HQI bulb experience?

[myzislow]

Does anybody have any experience with the Helios 20k in the 150w on an HQI ballast that they could share. I've tried searching but have found nothing regarding this bulb in the 150w version. I'm still trying to find the "it" bulb for me.

How does it compare to other bulbs you have tried; and more specifically to the xm and radium 20ks if you have experienced them all.

Thanks.

You mean Helios? They look nice but I didn't run them too long because I needed more PAR and had to change to a 10K lamp.

Yeah, helio(s) haha, my bad. You ran them in the 150 w version? How tall is your tank and what is your lighting set up? Thanks

It was a Helios fixture over a 125. It was only putting PAR of about 65 to the sandbed. Good reflectors would have probably gotten it up around 80. Tank was 23.5" tall.
