Robertson ISU232T8120 (3P20116) Electronic Fluorescent Ballast, for 1 or 2 T8 Fluorescent Lamps Between 17W-32W (F17T8 Through F32T8) or 1 F40T8 Lamp, Instant Start, 120V (Qty 1)

I bought two of these and they replaced my accupro 2321P-120-1 T8 ballasts. easy install and working like a charm!!

I wasn’t sure I needed these until I installed them. I had I bulb not lighting in two of lights. Pretty easy install, simple wiring instructions and the lights worked as suppose to. Recommend these ballast as fit like a charm. Pretty much anybody would have the skill to install

Awesome! Very easy to install and the diagram on the unit helped me out. The ballast is a little smaller than the previous one but it all works and I am happy with Robertson products.

No issues with replacing the old one except I needed to supply my own wire nuts. The product works perfectly, installation was straightforward, and it was the best price I could find.

The light in my kitchen suddenly stopped working. When my husband opened the fixture to check what was wrong, he realized that this specific piece had burned out. We ordered this replacement part on Amazon. Since we have Prime, it arrived in about 5 days. It took a little longer because of where it was shipping from, but when it arrived it was exactly the part we needed. My husband was able to install it without any problems, and the kitchen light started working immediately. Before replacing this part, the light would not turn on at all, but after installing it everything worked perfectly again. It has now been more than 3 months and it is still working without any issues. This saved us a lot of money because we didn’t have to hire someone to fix the light—we just replaced the part ourselves. If you need this replacement piece, I would definitely recommend it.

Lights come on. The buzz is gone. It's far lighter and narrower than the ballast it replaces, but the right length for the original mounting screws.

Item worked perfectly

I had an electrician install this new ballast. It was so light weight compared to my old one. I watched the electrician put it in but at almost age 86, I didn’t want to try. It seemed fairly easy to install. My ballast was put in my flora cart which is a great plant stand no longer being produced, which is too bad because it is a lovely stand. Mine holds 2 trays on each shelf and each shelf holds 2 48 inch bulbs which are T8 48 inch fluorescent tubes. When he put in the first bulb, it lit up immediately. My old ballast seemed to need both lamps in before it would light correctly.

Works perfect.

My light had completely died when it was on. Figured out was the ballast. Swapping was easy for someone with no electric background and now the light works once again. Plus the price was much cheaper than buying local.

installed and lights up bright and quick

Great deal

Fonctionne parfaitement, bonne qualité.
