Will my 400 Watt MH PFO ballast run...

...these bulbs: http://www.halloweeneffects.us/EL_BLK400_400Watt_UV_Blacklight_Replacement_Lamp_p/el-blk400.htm

We want to use them in a black out pep rally at my kid's high school...since the cheerleaders have no budget for pep rallies the money comes from my pocket! I would like to just buy the bulbs if I can and use the tank ballasts and pendants.

I would think that they would since they are the same style of light. You may want to contact the seller of them and see if a magnetic MH ballast will fire them first and see if they can give you info on it.

Oh heck yeah, I may buy that as an actinic light.

Add a little music and flashing lights and your corals will have their own little disco party!

I wonder what a tank with awesome corals would look like with that bulb!?!?!!!!! I never considered that.

It Looks Horrible. The water looks very cloudy. Black Light makes it look more like a solid purple block with out the 15K's on.
