madmax7774 October 24, 2007 Share October 24, 2007 For what it's worth, I just replaced my XM 250W 10K bulbs. Johnny from BRK uses ushio bulbs on his personalk tank, and I liked the look of them in his tank. I got a set for mine, and WOW what a difference. Ushio bulbs *for me at least* are definately a step up from XM. John Link to comment Share on other sites More sharing options...
zoozilla October 24, 2007 Share October 24, 2007 (edited) I may give this a try. What supplements do you use (T5 or VHO)? Edited October 24, 2007 by zoozilla Link to comment Share on other sites More sharing options...
madmax7774 October 24, 2007 Author Share October 24, 2007 For supplements, I have 2 48" VHO actinics (110W each). The combination of them, plus the ushio bulbs is stunning. The color on my system seems to "pop" alot more for me. I am just thrilled with the look of the tank. Link to comment Share on other sites More sharing options...
jamesbuf October 24, 2007 Share October 24, 2007 Are the Ushios also 10K? Are they SE or DE bulbs? Link to comment Share on other sites More sharing options...
madmax7774 October 24, 2007 Author Share October 24, 2007 The ushios are the exact same bulb as the old XM ones were, just different brand. Single ended Mogul base 10,000K 250W ushio bulbs. Running on a Pair of ARO electronic ballasts. My reflectors have not changed either, everything stayed the same except the bulbs. Link to comment Share on other sites More sharing options...

Running on a Pair of ARO electronic ballasts. My reflectors have not changed either, everything stayed the same except the bulbs. I also wonder if they would be equally as brilliant on the magnetic ballast? I am about 1 month away from changing bulbs and this might be a good change for me. How did you acclimate the tank to the new bulb? Link to comment Share on other sites More sharing options...
madmax7774 October 25, 2007 Author Share October 25, 2007 on my aquacontroller, i broke the light on period down to 2H on 1H off and shortened the duration by 4H. I will gradually increase back to the old schedule over time. i have no idea about par, I don't bother with that. I have great growth, and thats good enough for me Link to comment Share on other sites More sharing options...
