No, the radium bottom measurment was at 18.5" the 10000K was at 27" I expect that the radium will be around 100 PAR at 27" this is why I am using 12" as the standard not a deeper one .. as you can't compare 27" in all tanks but 12" can be.. for PAR levels the 10000K is higher all around.. the difference is in what the owner wants.. do you like a overall "Blue" look or do you want a white look with blue highlights.. ect...

I am starting to develope my own theory on color of the corals and it seams to me it is more reliant on ALK than light (as long as the min lighting requirments are met) I have seen this in my own tank.. color increase dramaticly with no change in light but a large change in Alk, and I think Brad is starting to wonder the same things... I have always stated that I don't beleive that light is the major factor, just take a look at all the different types of lights on tanks that have wonderfull color.. there is no end to the combanation and seams to be no rhym or reason when it comes to looking at lights alone.. Hmm maby this is material for another thread / poll
