Review on 💡 Optimize Lighting Performance with Philips RELB2S40N Ballast Bulb Electronic by Dan Barrett

Works as intended. This ballast is slightly smaller and lighter than the original, but fits perfectly in the existing bracket. I had to cut long wires to connect to the existing wires on the tube contacts. Remember that you will need 6 small to medium sized wire nuts (blue or orange) to make these connections.
