Need to test 250W bulbs

[Janina]

I just ordered 2x250W bulbs and put them in my fixture and neither fires. I did also replace both of my ballasts. NOw I don't know what part of the system isn't working. COudl be the ballasts although both are still humming. COuld be the capacitors or the bulbs and if it isn't one of those three, then I have no clue what the problem is. So I need to eliminate the bulbs to start with. BTW, I know it's not my wiring ability because I got the manufacturing to tell me which wire to connect to which

Anybody that runs 250W bulbs that lives close to COventry that could let me test out my bulbs?
