USHIO 10k 250w SE bulb

well i bought 2 new bulbs from a guy, figured they were the same thing.  well one can work with my ballast and the other can't.  This bulb will only work with electric probe start ballast i think.  it does not have an ignitor built in the bulb i dont think.  from what i have read from about the ushio bulbs i could find it said they would work on any ballast but this one won't so its up for grabs for 50 bucks

 

yeah wont run on the M58 will run on the m137 let me see if i can get a link

 

ummm nevermind i didn't look at the wattage on the bulb....he didn't even send me a 250w its a 175 so he is gunna have to find the 250w one and send it to me so this bulb is not forsale now so can someone delete this post....thanks
