Review on ⚡️ KEB 220-1 TP Electronic Ballast with EMI Suppression - Keystone Ballasts by Francisco Garcia

This ballast has non-standard wiring. In addition to the power wires, 4 red and 4 blue wires come out of the ballast. There is no universally accepted yellow. You need to remount the tombstones. Usually 2 red, 2 blue and 2 yellow wires come out of the ballast. This is not a simple wiring change. You need to connect blue/red to yellow, remove the black jumper from the tombstone and connect it to the other red/blue wires. I bought 4 of these ballasts, but the installation is too difficult for me. I will not buy this ballast next time.
