Review on Robertson Worldwide ISL432T8HEMV AH 3P20160 120-277V 50-60Hz High Power Factor 4 F32T8 Linear Lamp Fluorescent eBallast by Will Rahman

As long as three are connected. Saved a lot of money buying new mounts. The change was very easy and quick, nothing complicated. I'm glad I bought new tombstones to replace a couple of broken ones. They work great with instant power on. A disappointment, I went to Robertson Worldwide to find out who they were. The website states that this ballast was manufactured by the union in the United States. What I said was made in China. I made my purchasing decision based on this application from Robertson Worldwide. I will buy them again, don't worry about dishonesty.
