You will find that most modern light fittings now a days have what we call drivers (LED drivers are devices which regulate and supply the power used to 'drive' runs of LED strip lighting. Similar to traditional transformers, they transform mains voltage alternating current (240v AC) to a lower voltage.) You will need to connect this driver to the cable which goes to the first lamp and then the rest is pretty self explanatory. https://www.amazon.co.uk/AIBOO-Linkable-Lighting-Dimmable-Hardwired/dp/B07798JV55/ref=sr_1_290_sspa?dchild=1&keywords=Under+Cabinet+LED+Strip+Lights&qid=1615901528&sr=8-290-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUExN09WVzA4NzYyM0s5JmVuY3J5cHRlZElkPUEwODQ5NTkyMVFQNlVDVDFNWkJUWCZlbmNyeXB0ZWRBZElkPUEwMTk1Nzg4MU5IQk1CM0c5NDVDWCZ3aWRnZXROYW1lPXNwX2J0ZiZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU=
