rong666 Posted April 11, 2006 Share Posted April 11, 2006 hi, Well, I am overdue to replace my bulbs and was thinking of switching to 20k. My current setup is 2x250watt single end 14k hamilton metal halide with no actinc supplement. I have been happy with these bulbs, but would like a little more blue. Any suggestions on a brand of bulb? I would like a nice balanced color but obviously (20k) also want a decent amount of blue. thanx in advance. -Ron Quote Link to comment Share on other sites More sharing options...
impur Posted April 11, 2006 Share Posted April 11, 2006 What kind of ballast are you using? Are you looking for more PAR or just a bluer look? Quote Link to comment Share on other sites More sharing options...
Michael7979 Posted April 12, 2006 Share Posted April 12, 2006 look into Radiums...I like mine but they are 400w Quote Link to comment Share on other sites More sharing options...
rong666 Posted April 12, 2006 Author Share Posted April 12, 2006 it is a ballast from aquariumlights.com . I believe it is magnetic and not electronic. As for par rating, I am not that concerned. As far as I know, the bluer you go the lower par you get right? I get great growth out of my 14k hammies. - I have heard good things about the radiums. thanx for the input. -Ron Quote Link to comment Share on other sites More sharing options...
Theron Posted April 12, 2006 Share Posted April 12, 2006 I have been pretty happy with my 400W 20k xm bulbs. Quote Link to comment Share on other sites More sharing options...
impur Posted April 12, 2006 Share Posted April 12, 2006 I love my 14k hammies too, perfect mix of color IMO. You could try the 15k XMs, and if you have the $ the radiums get great ratings. Quote Link to comment Share on other sites More sharing options...
