Ballast and t5 ?

[knap_123]

I’m trying to replace a ballast, the white one. With the black one I bought at lowes for a 2 bulb 24watt diy fixture. I wired it up but could not get the bulbs to come on. Is it compatible with the white ballast?

It looks like your old ballast is a HO ballast - the most common type of T5 for aquarium. The new seem to be a HE (or standard) type of ballast - most used in real estate lighting where efficiency is most important.

From here

So that means it will not turn the bulbs on? Sorry, I’m not to smart in these areas. Lol I have the exact ho ballast on its way from brs. But if the other is not going to work I can return it to lowes before I loose the receipt.

It can still be that you have bad lamps but probably will in not work for your 24 W HO lamps. You have to look at the spec (red circle)
