First, there is really nothing wrong with your vho lighting.

I used 400,s because of the high colour temp. When increasing the colour of the bulb, the wattage needs to be increased to compensate for par.

A nice option for your tank would be a pair of 250 watt Iwasaki,s. Plus a pair of vho actinics. The 65K Iwasaki in the 250 watt version is, IMO, one of the best halides. Good price, good longevity,{ I have run them for over 2 years }, and a nicer colour than the 400 watt version.

The tank would also have a nice colour with the pair of actinics. Under these lights, you could keep clams and the most light demanding sps.
