Odyssea Light fixture problems

I have a 750W Odyssea metal halide light fixture. 2X 250W metal halide bulbs, 250W actinic T5s.

I know it's pretty cheap fixture, but it's worked great for the past year. Tonight I replaced the 15 000K stock MH bulbs that came with it (it's been a year) with 10 000K 250W coralife bulbs. In the process, I broke one of the original bulbs.

The problem is that neither of the new bulbs will ignite. When I swap out the not broken original bulb, it ignites no problem, but nothing I do will make the new bulbs, which should be identical except for colour temp and manufacturer, ignite.

At this point, my tank has no lighting and I'm kind of freaking out. Is there something obvious that I'm missing? They're double ended bulbs for a double ended fixture, shouldn't they just ignite?

the bad part with oddysea is that you have to use thier bulbs so you may have to order from them and try to get them to rush ship it for you. some of the other bulbs from other mfg wont work from what i have read... when i ordered my lights recently i ordered extra bulbs tohave on handfro this situation.

Really? I had read so many forum posts bout people upgrading this fixture with different brands of bulbs without any problems so I thought I was OK. I don't much want to keep using their brand of light bulb either, but wow, upgrading to a new fixture for however many thousands of dollars right now is definitely not in the budget.

maybe there is somthing wrong with your new bulbs? try a different brand its worth a shot.

I'm a super newb when it comes to all things electronic like this, can the ballasts determine whether or not the bulbs ignite even if the bubs are the same wattage?
