Michael7979 Posted June 1, 2009 Share Posted June 1, 2009 I am looking to replace my MH bulb that is over my grow-out/frag tank. It is a SE bulb and it will be fired by a PFO ballast, (non-HQI). I have never had 250w bulbs before except what is over the tank now, a cheaper bulb. So what kinda bulbs would you use? Want to stay in the 15-20k spectrum. So fire away.

Kshack Posted June 1, 2009 Share Posted June 1, 2009 Is it a PFO pulse start? I have a Radium and a Reflux 20K on my PFO Pulse start and I like both (250). Quote Link to comment Share on other sites More sharing options...
Michael7979 Posted June 1, 2009 Author Share Posted June 1, 2009 Don't really know. What markings would it have? I will have to look. Quote Link to comment Share on other sites More sharing options...
Michael7979 Posted June 1, 2009 Author Share Posted June 1, 2009 I don't see anything on it that says pulse start or anything else. Quote Link to comment Share on other sites More sharing options...
impur Posted June 1, 2009 Share Posted June 1, 2009 I like the 14k Hamilton bulbs. Perfect blend of color IMO. Quote Link to comment Share on other sites More sharing options...
