This is a DIY modification for the enthusiastic hobbyist!! Moderate skills are required. It is important that you install this yourself, as this means you can maintain it yourself too. We all know that battery coil spring contacts can be fussy, especially when bashed about.
*Modification is suitable for Nora 4 and Edna 2 lamps. Edna 2 lamps sold prior to Dec 2021 would require a software update. We will offer software upgrade in the future if this leftfield battery option proves popular!
