Steve,

I still don't find PC's are as intense as a point source light. They may be bright(which I know they are) but they don't do the same for me as a MH.

PC actinics. If they are 03's like is claimed then they are a violet actinic. As are the phillips and the URI VHO's. They peak at 470nm. not 450. That puts them in the violet range not blue. I want blue. Hence the MH blue bulbs. I don't know how accurate this is but blue is more readily useable by corals than violet or other wavelengths with all the reading I have done. Actinics are violet. Close but no cigar.

As it stands now I am even concidering trying the 150W 50KK that Adam reminded me existed. The ballast is easy to get to run these puppies and they have the highest blue peak of any MH I have seen.

In the end I'll still go MH above PC. I want to ditch ALL the fluorescent lamps in my hood. Save maybe one phillips 03 for 1/2 hour before and after all the MH turns on.

MH just has something that fluorescent doesn't have. Point source intensity.

For the most part all of this curiosity is for asthetics and my own eyes. But a small part is due to the spectrum make up of my 65KK. If I can fill in the one area it is lacking in who knows what may happen. :D
