Review on ⚡ Enhanced Efficiency: Robertson 3P20116 EBallast ISU232T8120 for Optimal Lighting Performance by Jeff Rhodes

Replaced a 40 year old Robertson ballast with this one. This was a 2 bulb setup with the original ballast having 2 blue, 2 red and 2 (I think) given the age of the unit which started out yellow. In any case, he also had white and black. At first I couldn't figure out why it wasn't working until I watched a few videos on You Tube. They didn't specifically address my issue, but gave me an idea of how to troubleshoot connections. The light block works perfectly. By the way, the original ballast weighed between 3 and 4 pounds in my opinion. This block weighs about 1/4 lb. I took a chance buying this unit because I would save about half the price at Home Depot and gas is on the rise and I need to take that into account when making my purchase as well. great device and highly recommended
