Adding Actinic or is there a bulb out there?

[lil.guppy]

I have a 150 watt HPS 16,000 Lumen Bulb fixture over my zoanthids and my zoas and other coral have no color what so ever. I knew this was going to happen considering its just a grow light.
My question is...is there a bulb that I can put in this fixture that will bring the color of the coral out or do I have to get a actinic suppliment fixture to add to what I have? If so does anyone know of any?
The tank is about 4 feet across and the water is only 4-5'' deep

I know some brands are bluer than others but I can't point you to a specsific bulb for your unit. I switched to Phoenix 14000K MH bulbs and they are really blue and bring out the colors. Not sure if you could go to a 20k bulb if that would help. Otherwise, I guess you would need to find a way to add actinics.

It would have to be a single socket bulb (the thick round ones) and its an HPS light fixture not a metal halide. The maker of this unit said I might be able to find a 150watt bulb MH that would work in it but he doesnt know how long it would last considering I dont have the components in the unit that you would find in a traditional MH unit. This unit is meant for growing plants
