Can a URI A4 vho ballast run two 80w t5 bulbs?

[irishfanrock34]

I was given an odyssea 72 inch ho t5 fixture with the timer. It has ati bulbs in it but one of the ballasts stopped working. He gave me a URI A4 vho ballast that he said was made by ice cap as a cheaper version of the 660. He told me to take the bad ballast out and throw this one in to run two of the 80w t5 bulbs. Can this be done ?

Should be fine.

Ok. Someone told me it would have to be ran outside the fixture because it may get too hot and someone else said it would severely shorten the life of the t5 bulbs.
