Affordable and Reliable
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.

Worked Flawlessly for My Application
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.

Exact Replacement Part โ Fixed My Kitchen Light and Saved Me Money
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 didnโt have to hire someone to fix the lightโwe just replaced the part ourselves.If you need this replacement piece, I would definitely recommend it.

They work.
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.

A Game-Changer for DIYers
Installation was a breeze, and the user-friendly design of the eBallast made it a perfect fit for my DIY project. The clear instructions provided made the process smooth and efficient. I appreciated the compatibility with both 1 and 2 Lamp F32T8 fixtures, giving me flexibility in choosing the lighting configuration that best suited my needs.One of the standout features of this eBallast is its Instant Start capability. The lights come to life instantly, eliminating any frustrating delays in illumination. This is particularly advantageous in spaces where quick and reliable lighting is essential, such as workshops or garages.In conclusion, the Robertson 3P20116 eBallast is a fantastic choice for DIYers looking to upgrade their lighting setup. It's a cost-effective solution that doesn't compromise on quality. The ease of installation, compatibility with different fixtures, instant start capability, and energy efficiency make it a stand-out performer in its category. I highly recommend the Robertson 3P20116 eBallast for anyone seeking an affordable and reliable lighting upgrade.

Easy peasy
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.
