Where I live, we have a large property. The EC has simply got on with upgrading lighting in a piecemeal fashion over years, for both lighting quality and better electrical efficiency. We added a few lights in dark spots along paths and replaced existing fluoro tubes with LED DIY retrofit kits when they needed replacing. Where a fitting needed repair, we got an electrician to fit an LED fitting. We mentioned the improvements at various AGMs but it was never the subject of a new by-law or meeting resolution. The EC simply regarded it as part of its duty to repair and maintain and ensure safety.
