Is it true that NO (even over driven 2X) won't have enough intensity to provide enough Lummens at the bottom of the tank? Let me know if I understand the properly. If I overdrive the 4 NO lights 2X then it would be like having 8 NO's instead of 4 NO. But according to StirCrazy, 4 NO's are not even half as intense as 2 96W PCs. Assuming Stircrazy was not overdriving his lights, then even if I overdrive them (double the PAR, I think?), it will still not have a PAR Value as high as 2 96W PCs. Is this correct?

StirCrazy - are your T8's on a workhorse 7 Ballast?

Do others believe I should have no troubles keeping softies, LPS and Sea Anenomes (BTA or Seabae) with 2 96W 65000K PCs and 2 48" NO attinics? What do you think about using 4 48" 65000K NO (overdriven 2X) and 2 48" NO attinics? Would this be just as good? By the way my tank is about 20" high with about a 4 inch sandbed.

One more question: Does anybody know a good place to get end caps for PC lighting? Are they about the same price as the end caps for NO lighting?
