Ballast for 150W Iwasaki?

[Cresta]

Does anyone know where can I get a cheap ballast to run the new 150W 50000k Iwasakis? Cheapest I've seen are electronic ones for about $130 each. Are the Advance ones any cheaper?

I'm going to use two to offset my four 250W 6500K Iwasakis. My VHO actinics aren't strong enough to do much.

If I'm not mistaken this bulb can be run on a MV ballast. I have seen Regent brand street light style lamps for sale at home centers and farm/fleet for about $50. HTH, Bill.

Maybe I need to look again, but Home Depot only sells the 100w and 175w light kits (outdoor home security lights). I can't find the 150w. I read that I can't and shouldn't overdrive the lamps.
