Challenge is to get right light, power and number of LEDs per metre which I did based on past experience. Ordered Splashproof by mistake as they were same price as IP21 and special connectors are required for each type. Worth ordering a spare connector to practice on with spare bit of strip light. They work very well, just ensure LED strip is pushed well in! Also worthwhile buzzing connection each time to ensure continuity and correct polarity. Stick on very well, double sided tape held connector flush with surface - not essential but a nice touch.
Last installed something similar many years ago, much improved, connectors better. Wife delighted with result.
