How long do t5 bulbs last.

I know when you overdrive t5 bulbs they last about 9 months. How long would they last with an A4+ ballast? The canopy will also have two fans built in. Also should I have a fan blowing on each row of endcaps?

The URI A4 ballast (if that is the one you have), is the same as the icecap 660 and will overdrive the bulbs the same so you will get the same life out of them.

To get the max light out of the bulbs, have a fan blowing on the ends with the label to keep them cooler.
