Thanks Christy:

From what I have been told they are supposed to burn whiter using strictly a Mercury Vapour ballast. However even PFO suggests they will only burn slightly bluer. Don't know where they get the blue from as they are very yellow. I will upload a pic tonight or tomorrow.

You wouldn't happen to have a pic of the iwasaki's over your tank without actinics for comparison.
