Here is a couple of pics of an Iwasaki and Radium bulb. I am concerned the Iwasaki is not burning as white as it should if it was run off a Mercury Vapour ballast. Anybody care to comment if this is the correct color of the Iwasaki, or would a MV ballast burn whiter.
left - Radium 400 watt on a 430 watt Son Agro ballast
Right - Iwasaki 250 watt DL/BH E39/41R on a Advance 71A57A0 MH
Light over the refugium is a 175 watt Coralife 6500K MH
Second pic is Iwasaki only
Not the greatest pics, but the colors are pretty accurate. Looks like I better hook up the actinics if I plan on switching back to the Iwasaki's!
