Review on 💡 Optimize Lighting Performance with Philips RELB2S40N Ballast Bulb Electronic by Mark Hobbs

2 tubes slowly lit. They need 3 seconds to fully turn on. The old ballast, ACCUPro ap-rs-240rs-120, switched on immediately. Wire nuts are not included. If your light has never been ballasted, you will most likely need to cut the yellow, red, and blue wires that power the lamps. The wires on the ballast are long enough. If it wasn't in the basement I would send it back. Installation is no more difficult than any other.
