ati,kz,geissmann and uvl bulbs are all great bulbs with atis blue plus and aquablues being my favorite not mention some serious par. I agree, dont to skimp out on quality bulbs and reflectors which will make a huge difference in performance. Not too many places out in the IE that readily have these brands available, i think Mystic Reef in Jurupa is the closest and i dont believe they carry atis' but you could try giving them a call. I order mine through Reefgeek which carries most brands, theyre pretty cheap, have great customer service and have fast shipping, i usually recieve mine in 2-3 days. HTH.
