Robertson ISA332T8HEMV (3P20167) Electronic Fluorescent Ballast, 120-277Vac input, 2 or 3 T8 Fluorescent lamps between 17W-32W (F17T8 through F32T8) or 2 F40T8 Lamps, Instant Start, 120-277V (Qty 1)

Bought this to replace the old ballast that broke after 15 years of usage. The ballast is for 3 T8 linear lamps. The connection wires are very long. I cut the wires to the appropriate length to remove the old ballast and install the new one to the existing lamp hood. The process took probably about 10 minutes. The lights are working again.

It worked! Can't say much more. It is a generic electronic ballast for fluorescent/LED light fixtures that aren't sealed and still use individual tube bulbs. It replaced an electronic ballast that had failed and prevented good bulbs from lighting up. This ballast was designed to handle three bulbs, but I only needed to light two. The wiring diagram on the ballast clearly showed what to do with the extra wires. I would buy it again. But the product description on Amazon could have explained the ballast's three-bulb capability better so I would not have been so surprised when I opened the packaging.

The install was simple and it works perfectly.

Product worked well and was easy to install, but it was shipped in a plastic bag. Come on, Amazon! You can do better. Reducing packaging is one thing, damaged products are another!

I checked the numbers on my existing ballast so that I'd get the proper size. This was it and just perfect! I'm so happy I didn't have to replace the whole lighting fixture! I like my current fluorescent light fixture and didn't want to replace it. Plus, it's a pain for one person alone to replace things like large light fixtures and ceiling fans. If you like your current fixture, or can't afford to replace it, try replacing the ballast first. That's the part the tends to go wrong on those fixtures.

I have now replaced several of the ACUUPRO brand Ballast's with the Robertson Ballast. I have found that the longevity of the Robertson is much much better then the OEM Brand (ACUUPRO). Installation was very straightforward. I used "IDEAL" wire connectors (which come in all different capacities for connection) and these worked perfectly.

Perfect replacement for the original ballast. Works great so far.

Works like it should
