HQI bulbs
 

The one lighting supplier that was able to provide me a magnetic ballast still wanted something like $220 per unit for the 250W size. So for your $130 price or whatever it was I still want to get ahold of that place and either buy from them or get a part # that I can try to find locally. Can you send me the info when you get a chance please? Click on my profile thingy to get my email address. Thanks!
