No, sorry I removed the 2x T5NO.

This is roughly based on hoppy's work here:
Lighting an Aquarium with PAR instead of Watts
and some napkin math based comparisons of the chart below, I suspect I am over 100 PAR with my CFL setup

*edit to add*
When looking at this chart note that these bulbs were mounted vertically - not horizontally as I did. This has been shown to be more efficient (vertically)

Take a look here:

I need to hookup with a local aquatic club with a PAR meter and really get some numbers.
